Abstract:

Poor emergence and low seedling vigor are characteristics of many supersweet sweet corn (Zea mays L.) cultivars carrying the shrunken-2 (sh2) gene. Four sh2 sweet corn cultivar seeds [`How Sweet It Is' (HSII), `Crisp N' Sweet 711' (CNS-711), `Sweet Belle' (SB), and `Dazzle' (DZ)] were solid-matrix-primed (SMP), SMP with sodium hypochlorite (SMPcl), treated with a fungicide combination (F) (Imazalil + Captan + Apron + Thiram), or primed with the aforementioned fungicides (SMPf). The seed treatments were tested in the laboratory and the field. Seed imbibition and leachate electrical conductivity were lower in SMP seeds than in nonprimed seeds. In the field, emergence percentage and rate of CNS-711 and SB (high-vigor seeds) were not improved by the seed treatments compared to the nontreated seeds. Emergence percentage and rate of HSII and DZ (considered low-vigor seeds) were improved as a result of SMPcl, SMPf, or F treatments compared to nonprimed seeds. Compared to the F treatment, the SMPcl presowing treatment increased DZ seedling emergence rate and percentage. The combined SMP and seed disinfection via NaOCl seems to be a promising fungicide seed-treatment substitute that improves the stand establishment and seedling vigor of sh2 sweet corn cultivars. Chemical names used: 1-[2-(2,4-dichlorophenyl)-2-(2-propenyloxy)ethyl]-1 H imidazole (Imazalil); N-[(trichloromethyl)thio]-4-cyclohexene-1,2-dicarboximide(Captan); N- (2,6-dimethylphenyl)- N -(methoxyacetyl)alanine methyl ester (Apron); tetramethylthiuram disulfide (Thiram).

Abstract:

The objective of modern seed-coating technology is to uniformly apply a wide range of active components (ingredients) onto crop seeds at desired dosages so as to facilitate sowing and enhance crop performance. There are three major types of seed treating/coating equipment: dry powder applicator, rotary pan, and pelleting pan with the provisions to apply dry powders, liquids, or a combination of both. Additional terms for coatings produced from these types of equipment include dry coating, seed dressing, film coating, encrustments, and seed pelleting. The seed weight increases for these different coating methods ranges from <0.05% to >5000% (>100,000-fold range). Modern coating technology provides a delivery system for many other materials including biostimulants, nutrients, and plant protectants. This review summarizes seed coating technologies and their potential benefits to enhance seed performance, improve crop establishment, and provide early season pest management for sustainable agricultural systems.

Abstract:

The effect of treating aged onion seeds with 5-azacytidine (5-aza) on germination and vigour was evaluated. Seeds of two onion varieties, 'Bhima Raj' (BRJ) and 'Bhima Red' (BRD) were treated with 0, 10, 25 or 50 μg mL–1 5-azacytidine (a DNA demethylating agent). In comparison with the control treatment (0 μg mL–1 5-azacytidine), treatment with 5-azacytidine enhanced seed germination, seedling length, seedling dry weight and seed vigour indices. 5-azacytidine treatment also increased the activity of superoxide dismutase (SOD) and total antioxidant capacity (TAC). Seed treatment with 5-azacytidine has the potential to enhance the viability and vigour of aged onion seeds. This study provides phenotypic and biochemical data for further exploring the role of DNA methylation in understanding the process of seed ageing.

Abstract:

Seed priming with sorghum water extract (SWE) enhances crop tolerance to salinity stress; however, the application of SWE under salinity for camelina crop has not been documented so far. This study evaluated the potential role of seed priming with SWE in improving salt stress tolerance in camelina. Primed (with 5% SWE and distilled water-hydropriming) and nonprimed seeds were sown under control (no salt) and salt stress (10 dS m−1) conditions. Salinity reduced camelina’s emergence and growth, while seed priming with SWE improved growth under control and stress conditions. Under salt stress, seed priming with SWE enhanced emergence percentage (96.98%), increased root length (82%), shoot length (32%), root dry weight (75%), shoot dry weight (33%), α-amylase activity (66.43%), chlorophyll content (60–92%), antioxidant enzymes activity (38–171%) and shoot K+ ion (60%) compared with nontreated plants. Similarly, under stress conditions, hydrogen peroxide, malondialdehyde (MDA) content, and shoot Na+ ion were reduced by 60, 31, and 40% by seed priming with SWE, respectively, over the nonprimed seeds. Therefore, seed priming with SWE may be used to enhance the tolerance against salt stress in camelina.

Abstract:

Seeds of three columbine species, Aquilegia caerulea James, Aquilegia canadensis L., and Aquilegia hinckleyana Munz., were studied to determine if seed priming can be used to enhance or completely bypass stratification. The effect of priming varied among species. Germination percentage of nonstratified, primed seed of A. caerulea was as high as nonprimed stratified seed at the termination of the study. Nonstratified primed seeds of A. canadensis did not perform as well as stratified seed, but priming did enhance the germination percentage of stratified seed. Priming had no effect on seed germination–of A. hinckleyana.

Abstract:

Abstract The effects of magnetic field treatments of French marigold seeds on germination, early seedling growth and biochemical changes of seedlings were studied under controlled conditions. For this purpose, seeds were exposed to five different magnetic seed treatments for 3 min each. Most of seed treatments resulted in improved germination speed and spread, root and shoot length, seed soluble sugars and a-amylase activity. Magnetic seed treatment with 100 mT maximally improved germination, seedling vigour and starch metabolism as compared to control and other seed treatments. In emergence experiment, higher emergence percentage (4-fold), emergence index (5-fold) and vigorous seedling growth were obtained in seeds treated with 100 mT. Overall, the enhancement of marigold seeds by magnetic seed treatment with 100 mT could be related to enhanced starch metabolism. The results suggest that magnetic field treatments of French marigold seeds have the potential to enhance germination, early growth and biochemical parameters of seedlings.

Abstract:

Present study was conducted to analyze the anatomical structure of seed to study the dormancy behaviour in Chamaecrista absus. Seed germination behaviour was also studied after breaking the seed dormancy by artificial seed treatments. The anotamical studies revealed that seed has apical hilar region and seed coat has four layers consisting of outer cuticle, sub cuticle, palisade layer and inner tegma leading to physical dormancy. Outer cuticle and sub cuticle layers are very hard to break naturally and hence seeds possess hard seed coat dormancy. This physically hard seed coat should be made soft to enhance germination. Studies to break dormancy were conducted involving treatments like hot water, hormones and in combinations of both. The results revealed that seeds dipped in boiling water made inner layers permeable for water absorption in hilar region and thus germination enhanced. In specific seeds treated with boiling water for 5 minutes recorded higher germination (82 %) over untreated control (26 %). . Other artificial treatments with hormones gibberellic acid (33 % ) and ethrel (34 % ) did not enhanced the germination significantly over control. C. absus has hard coat dormancy and can be overcame by treating seeds with boiling water treatment.

Abstract:

Endophytes are important microorganisms that enhance the plant's stability through a symbiotic relationship, without any harmful effects and symptoms in the host plant. To study the effect of endophytes on overall performance of COH(M)8 hybrid maize seeds, the present study was conducted with different endophytic seed priming for 12 hrs duration with Beauveria bassiana @ 5% (T2), Metarhizium anisopliae @ 5% (T3) and Bacillus subtilis @ 8% (T4) along with hydro priming (T1) and untreated control (T0). The seed priming treatments with all the above three endophytes enhanced the seed quality parameters, among which M. anisopliae @ 5% (T3) registered maximum increase of germination (4.34%), shoot length (20.73%), root length (15.04%), dry matter production (15.22%) and vigour index (22.68%) over control. Similarly, the seeds primed with M. anisopliae @ 5% (T3) recorded the highest value of dehydrogenase activity (0.441 OD value), α- amylase activity (2.06 mg maltose min-1) and antioxidant activity viz., catalase (1.55 μmol H2O2 min-1 g-1 protein) and peroxidase (0.87 U mg-1protein min-1). Results of this study revealed that the endophytes can enhance overall the seed quality in maize.

Full text

Abstract:

Many common agronomic practices affect weed seed dormancy and germination by influencing the microenvironmental and edaphic conditions surrounding seeds in soil. Factors such as light penetration, soil water content, soil fertility, and temperature are modified by tillage, planting, harvesting, and other production practices, resulting in enhanced or depressed weed seed germination. Changes in these environmental factors may also indirectly lead to alterations in phytohormone concentrations during seed development, which can subsequently affect dormancy status of the mature seed. Integrated approaches that place priority on depleting weed seed banks through interfering with dormancy or germination requirements have strong potential to enhance weed management aspects of agricultural systems.

Abstract:

Gentiana lutea L. (yellow gentian, Gentianaceae) is an important medicinal plant under protection as endangered species in most European countries. The aim of this work was to evaluate variation in seed mass, seed water content, and seed germination among 56 wild accessions of G. lutea. The effect of gibberellic acid (GA3), putrescine, moist chilling, and level of ripeness of seeds on subsequent germination was also investigated. Seeds of G. lutea showed physiological dormancy (final germination percentages ranged from 0% to 11%, depending on the accession) and GA3 enhanced seed germination drastically in all the accessions. The highest germination (99%) of GA3-treated seeds was reached at 15 °C. Final germination percentage and germination rate (as expressed by mean germination time), as well as seed mass and seed water content, varied significantly among accessions. In general, 1 year moist chilling did not significantly enhance G. lutea seed germination. For most accessions, no significant differences were found between fully ripe seeds and less ripe seeds for seed water content, seed mass, and seed germination. Applications of GA3 were always most effective than those of putrescine for increasing seed germination.

Abstract:

Seed germination is a critical parameter for the successful development of sustainable agricultural practices. While seed germination is impaired by environmental constraints emerging from the climate change scenario, several types of simple procedures, known as priming, can be used to enhance it. Seed priming is defined as the process of regulating seed germination by managing a series of parameters during the initial stages of germination. Hydropriming is a highly accessible and economic technique that involves soaking of seeds in water followed by drying. Biopriming refers to the inoculation of seeds with beneficial microorganism. The present study aims to investigate whether hydropriming and biopriming could enhance seed germination. Thereby, the germination of Medicago truncatula seeds exposed to hydropriming and/or Bacillus spp. isolates was monitored for two-weeks. The seeds were sown in trays containing two types of in situ agricultural soils collected from Northern India (Karsara, Varanasi). This region is believed to be contaminated by solid waste from a nearby power plant. Phenotypic parameters had been monitored and compared to find the most appropriate combination of treatments. Additionally, qRT-PCR was used to evaluate the expression levels of specific genes used as molecular indicators of seed quality. The results show that, while hydropriming significantly enhanced seed germination percentage, biopriming resulted in improved seedling development, represented by increased biomass rather than seedling length. At a molecular level, this is reflected by the upregulation of genes involved in DNA damage repair and antioxidant defence. In conclusion, hydropriming and biopriming are efficient to improve seed germination and seedling establishment in soils collected from damaged sites of Northern India; this is reflected by morphological parameters and molecular hallmarks of seed quality.

Abstract:

Salmonella enterica serovars and Escherichia coli O157:H7 have been associated with contaminated seed sprout outbreaks. The majority of these outbreaks have been traced to sprout seeds contaminated with low levels of pathogens. E. coli O157: H7 strains can grow an average of 2.3 log CFU/g over 2 days during seed germination, and Salmonella can achieve an average growth of 3.7 log CFU/g. Therefore, it is important to find an effective method to reduce possible pathogenic bacterial populations on the seeds prior to sprouting. Our objective was to assess the effectiveness of various dry heat treatments on reducing E. coli O157:H7 and Salmonella populations on mung beans intended for sprout production and to determine the effect of these treatments on seed germination. Mung beans were inoculated with five-strain cocktails of E. coli O157:H7 and of Salmonella serovars harboring the green fluorescent protein gene and then air dried overnight. Heat treatments were performed by incubating the seeds at 55°C for various periods of time. Heat-treated seeds were then assessed for the efficacy of the heat treatment and the effects of heat treatment on germination rates. After inoculation and drying, 6 log CFU/g E. coli O157:H7 and 4 log CFU/g Salmonella were detected on the seeds. Following heat treatment, pathogenic bacterial populations on the seeds were below detectable levels (<1 log CFU/g), but the germination rate of the seed was not affected. Thus, the risk of contamination and the presence of pathogens in the finished sprouts were greatly reduced via the seed heat treatment process.

Abstract:

It has been reported that a suit of plant traits can regulate the ant-seed interaction and subsequently affect the seed dispersal. However, the role of plant volatiles in attracting the ants for seed dispersal remains little examined. We used a Y-tube olfactometer to test behavior response of a keystone seed-dispersing ant (Pristomyrmex pungens Mayr) to leaves and seeds of five co-occurring myrmecochorous Corydalis species (C. wilfordii Regel, C. racemosa (Thunberg) Persoon, C. sheareri S. Moore, C. balansae Prain and C. incisa (Thunberg) Persoon). Of the five species, only C. wilfordii and C. racemosa leaves emits heavily volatiles. We also performed seed cafeteria experiments to assess the effect of leaf volatiles from C. racemosa on seed retrieval by presenting simultaneously the seeds near the fresh leaf and the leaf immersed by diethyl ether both in the field and lab. The experiment using Y-tube showed that the ants were only significantly attracted by the fresh leaves of two species, C. wilfordii and C. racemosa. The cafeteria experiments showed that ants spent less time to detect the C. racemosa seeds which were near the fresh leaf, and transported these seeds more quickly. This indicated that the leaf volatiles can function as an attractant for the dispersing ants, and ant preference in turn enhance the seed retrieval. The findings reveal that leaf volatiles can play na important but underestimated role in shaping the ant-seed dispersing interactions.

Abstract:

A novel delivery method for the application of bio-based biostimulants as seed coatings was developed using different sources of liquid and powder forms of vermicompost and soy flour. Micronized vermicompost (MVC) and soy flour (SF) were mixed in different combinations as dry seed coating blends and applied using rotary pan seed coating equipment. The physical properties of coated seeds were measured, and as binder concentration increased, coating strength increased. The rates and percentages of germination of the newly developed coating formulations of SF+MVC did not decrease the germination parameters and were not significantly different than the control. However, the SF, SF with concentrated vermicompost extract, and SF + MVC from dairy manure increased the seedling vigor index by 24, 30, and 39 percent, respectively, compared to the control. Plant biometric parameters and nitrogen uptake per plant were also significantly higher for SF and SF+MVC coated seeds than the control, in a greenhouse environment. This is the first seed coating study to show an enhancement of plant growth with vermicompost, and vermicompost in combination with a plant-based protein that serves as a dry seed coating binder and biostimulant, respectively. Seed coatings developed in this study can serve as a model for development of the delivery systems of seeds for the application of bio-based biostimulants to enhance early plant growth.

Abstract:

Pyraclostrobin (F500), an agricultural fungicide derived from the fungal sec-ondary metabolite strobilurin, is known to enhance growth and yield of cere-als when applied on healthy plants. A field experiment was conducted to evaluate the effect of Pyraclostrobin (F500) on growth and yield of healthy plants of fenugreek (Trigonella foenum graecum L.) var. Pusa early under field conditions. Pyraclostrobin (F500) was applied as a foliar spray in the four different concentrations (0.005 g L-1, 0.01 g L-1, 0.025 g L-1 and 0.1 g L-1), on 15th, 30th and 45th days after emergence of seedlings. Unsprayed plants served as control. F500 treatment enhanced the biomass (Plant height, fresh weight and dry weight) and yield parameters (Number of pods per plant, seeds per plant and 100 seed weight). Although enhancements in growth and yield parameters were observed with all the concentrations of F500 used, it was maximum at 0.01 g L-1 concentration. Enhanced biomass showed positive correlation with increase in yield and seed quality (seed weight per plant). Thus, F500 can be successfully employed as a foliar spray under field conditions to enhance the yield of T. foenum graecum.

Abstract:

Seeds of Lupinus havardii Wats. (Big Bend bluebonnet), a potential cut flower crop, were subjected to a variety of scarification and temperature treatments. Without scarification, only 10-20% of the seeds germinated within one week. Germination percentages increased sigmoidally as scarification time in concentrated sulfuric acid increased. Nearly 100% germination was obtained within one week after seeds were placed in sulfuric acid for 120 min. Nicking the seed coat with a razor blade also resulted in near 100% germination. Soaking the seed in water for 24 h failed to enhance germination. Soaking the seed in ethanol, methanol, or acetone for 2 h likewise failed to enhance germination. Total germination of scarified seed was >90% between 21 and 33C within 28 h. The most rapid germination occurred within a range of 24-29C. Above or below this range germination was delayed. At 35C, seedling, mortality was observed and total germination was reduced to <50%. Our data indicate that seed of this species requires scarification for optimum germination but the seed can germinate over a relatively wide temperature range.

Abstract The present research was conducted under laboratory conditions. The purpose of research was to investigate the potential of priming with press mud, peat moss, sand, gunny bags, compost, farm yard manure and moringa leaf extract (MLE) on seedling growth and germination capacity of maize seed. Untreated or non-primed seeds were used as a control treatment. Priming treatments improved germination capacity, stand establishment and seedling vigor, compared with control. Priming with moringa leaf extract enhance germination and seedling vigor of maize seed, compared with the control and other seed primed treatments. In moringa leaf extract primed seeds, root and shoot growth was improved. Overall, moringa leaf extract primed maize seeds performed better than all other treatments and it could be related by seedling vigor enhancement and lowering the mean germination time, due to imbibition of higher quantity of water and earlier enzymatic activity. The results propose that moringa leaf extract priming treatment had the potential to enhance germination, stand establishment and early growth of maize seeds.

Abstract:

The effects of CaCl2, GA3, and H2O2 priming on Isatis indigotica Fort. seed germination characteristics, seedling growth parameters, and antioxidant enzyme activities under salt stress were investigated. NaCl had an adverse effect on the germination and seedling performance of I. indigotica. However, these three priming agents alleviated salt stress by increasing the germination percentage, improving seed vigor, accelerating germination velocity, and establishing strong seedlings. The optimal concentrations were 15 g/L for CaCl2, 0.2 g/L for GA3, and 40 mm for H2O2. Seed priming treatments enhanced the activities of antioxidant enzymes in seedlings, such as superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT), under a salt environment, which reduced the oxidative injury caused by salt. Seed priming is a promising technique that can enhance the ability of I. indigotica seed germination when salt is present.

Abstract Planting using seed ball, where seeds are enclosed in materials and planted directly to the field by throwing the seed balls or using aerial planting. This technique has been considered to speed up the rehabilitation of degraded land and forest. Formulation of materials to enclose the seed is important and could be specific for different seeds. Therefore, this research aims to determine the appropriate formulation of seed balls to enhance seeds germination and their subsequent growth. The research was conducted from February-June 2021 in a greenhouse. Three formulas have been tested, i.e. 1) Formula A: clay and compost (1:1); 2) Formula B: clay, compost, and insecticide (50:50:1); 3) Formula C: clay, sawdust, bone meal, and vermicompost (8:8:2:1). The seeds used were seeds of durian (Durio zibethinus), jackfruit (Artocarpus heterophyllus), velvet apple (Diospyros blancoi), merbau (Intsia bijuga), and white teak (Gmelina arborea). The experimental design used was a completely randomized design (CRD) with 3 treatments and 3 replications. The fastest germination rate of durian, jackfruit, and merbau seeds was recorded on Formula A, while velvet apple and white teak seeds were on Formula C. The best height growth of seedlings was found using coating Formula C, i.e. 17.98 cm within 3 months after planting.

Abstract:

An 8-year-old loblolly pine (Pinustaeda L.) seed orchard was subsoiled by making one (single-rip treatment) or three (multiple-rip treatment) parallel rips on opposite sides of the trees. A nonsubsoil (control) treatment was also included. Seeds were extracted and sized into small, medium, and large. Subsoiling treatments had no effect on number or percentage of small, medium, and large seeds. The multiple-rip treatment produced significantly more seeds per cone than the control treatment, but no more than the single-rip treatment. Seed size did not affect seed germination, but strong clonal effects in seed quality and vigor occurred. There was no effect of any of the subsoiling treatments on seed germination. Any subsoiling treatments used to enhance tree vigor or to alleviate soil compaction in a seed orchard should have minimal influence on seed quality.

Abstract:

The consistent seed germination, early seedling growth, and uniform plant stand are crucial stages in the growth of crops. Uneven seed germination and seedling growth are responsible for low crop output. Studies have shown that the potential of seed preparation before planting enhances the development of crop from germination to maturity. Seed preparation has become a trend and a part of farming as it improves vegetative and reproductive growth and ensures the quality and quantity of the yield. Therefore, quality of seed can be improved through various seed preparation technique. Seed preparation method includes: priming, treatment, inoculation, etc. and all of these have significant effect on agriculture. Priming is a controlled hydration of seed done to trigger a pre germination activities. There are various methods of priming such as hydropriming, osmopriming, halopriming, biopriming and hormonal priming. Seed are also inoculated with various microorganism to enhance the activities like biological nitrogen fixation. To prevent the seed borne diseases seeds are treated with various chemicals like fungicides, insecticides etc. This review paper discusses about the important of quality seed and different methods of seed preparation for planting and approaching yield sustainability.

Abstract:

Casuarina cunninghamiana Miq. is an introduced species to Florida that has potential as a windbreak plant to help manage canker in citrus groves; however, only Florida sources can be used for that purpose. Local sources of Casuarina are generally adequate seed producers, but germination percentages are frequently poor. Thus, the causes of low seed germination and methods to improve germination were investigated using C. cunninghamiana and a local hybrid (C. equisetifolia L. × C. glauca Sieb. ex Spreng.). Seeds of the hybrid were larger and heavier (88 mg/100 seeds) than those of C. cunninghamiana (mean wt. 67 mg/100 seeds). Shrunken, insect-damaged, and empty seeds, present in all unsorted seed lots, were responsible for poor seed germination of the four seed sources studied. Petroleum ether separation improved germination by dividing seeds into floaters and sinkers. The floater fraction consisted of 47.5% to 93% insect-damaged seeds compared with 9.0% to 43.5% among sinkers. More than 50% of the sinkers were filled seeds and less than 21% in floaters. No empty seeds were sinkers except for one source of C. cunninghamiana. In sorted hybrid seeds, petroleum ether separation eliminated a large proportion of ungerminable seeds (floaters) and seed germination among sinkers was faster with a higher germination percentage than floaters. Cumulative germination of hybrid seeds in a trial involving two temperatures was 23.0% for sunken seeds at 30 °C at the end of 8 weeks compared with 1% of unsorted seeds. Temperature had no significant effect on seed germination. The germination percentage of hybrid seeds with seedcoats removed was 91.0% in the first week of culture compared with only 1.2% in the first week and 12.6% seed germination at the end of 8 weeks' culture of intact seeds.

Abstract Improved seed is one of the crucial ingredients for promoting agricultural productivity, farmers’ livelihood, and global food security. The present study uses an endogenous treatment regression model (ETRM) to evaluate the impacts of improved seed maize technology (ISMT) adoption on technical efficiency and productivity using data from maize farmers in northern Ghana. The findings show that ISMT adoption impacts positively on technical efficiency. Adoption of ISMT enhanced technical efficiency by 16.1% and increased maize productivity by 33.8%. The study recommends dissemination of improved maize seeds to farmers and other interventions such as provision of fertilizer to enhance farmers’ technical efficiency and productivity.

Abstract:

Plantings are commonly used in roadside reclamation for ornamental purposes and for increasing slope stability and road safety. However, the role of these plantings in restoring ecological processes, such as seed dispersal, has received little attention. We carried out a study to assess the potential role of plantings on roadside embankments to attract frugivorous birds and to enhance seed dispersal mediated by birds from the surrounding landscape. We examined: (1) bird species richness and abundance; (2) patterns of avian spatial distribution within embankments and (3) seed dispersal mediated by birds. Bird richness and abundance did not differ between embankments with and without plantings. However, birds were not distributed randomly within embankments, with levels of species richness and abundance for facultative frugivorous between 4.8–8 times higher in areas closer to plantings. An analysis of bird droppings showed that birds only dispersed seeds of the planted species since no seeds of woody plants from matrices were detected. These results suggest that plantings acted as selective bird attractors, providing food and perches for frugivorous species. Nevertheless, the scarcity of seed-dispersing birds in the surrounding agricultural landscape prevented plantings from enhancing seed dispersal and connectivity to adjacent habitat.

Abstract:

Heavy metal (HM) toxicity is vital environmental constraint that limits crop productivity worldwide. Several physiological processes necessary for plant survival have been found to be affected by HM toxicity. In recent farming, advanced mechanisms are being developed to overcome from the stresses to enhance the yield. The seed priming is an affordable method for plants to survive under abiotic and biotic stresses. Priming is useful for commercial seed lots by seed technologists to increase the vigor of the seeds in terms of germination potential and enhance the tolerance against various stresses. It also removes the pollution threats by minimizing the uses of chemical fertilizers. The seeds having deprived of quality in terms of seed germination and seedling characters ultimately affect the growth, photosynthetic performance and yield of the plants under HM stress. On the other hand seed primed with various seed priming methods such as hydropriming, hormonal priming, chemical priming, biopriming, magnetopriming and nanopriming perform well under HM toxicity. Seed priming methods have been considered as a unique approach to get rid of HM stress by enhancing the seed germination, seedling vigor, rate of photosynthesis, biomass accumulation and thus increase the crop productivity. The present review provides an overview of different seed-priming methods and their role in alleviation of adverse effects of HM stress in plants.

The objective of this work was to determine if KCl could be a useful nutrient primer for safe seed germination in maize crop under salt stress conditions. Seed priming was done using 50 mmol L‑1 of muriate of potash, and germination and seedling growth were evaluated after salt stress with NaCl up to 50 mmol L‑1. Another set of seeds was tested under the same salt stress conditions without priming. Under salinity stress, germination percentage, germination rate index, germination coefficient, and seedling vigor indexes were higher in primed seeds. In unprimed seeds, mean germination time increased, while the germination rate index and the fresh and dry matter mass decreased more sharply with salinity stress. The Na/K ratio was higher in unprimed seeds.

Abstract:

Seed-priming is a physiological technique of seed hydration and drying to enhance the germination. Seed priming treatments can be used to achieve even and earlier sprouts. A popular seed-priming practice which helps the seeds germinate faster is hydro-priming. Other studies have shown that seed priming with α-arginine promotes growth in sunflower. Pepper seeds germinate slowly and the aim of this study was to assess the effects of seed priming with α-glutamine and α-arginine amino acids in pepper seeds grown in different fertilization scheme. During the evaluation it can be concluded that seed-priming treatment with α-arginine and double distilled water speeds up the sprouting. At some variants, it was proven that α-glutamine seed-priming was inefficient. It was also found that fertilization schemes influence the germination and root growth in the following year.

Abstract:

Rapid seed germination and vigorous seedling growth are desired when establishing turfgrass lawns from seed. Low-dose concentrations of nonionic, block copolymer surfactants can have a direct effect on plant physiological functions and growth. The objectives were to determine if a low-dose application of a nonionic alkyl ended block copolymer surfactant applied directly to the seed, within a film coating, would 1) influence speed, synchrony, and final germination percentage (FGP), and 2) enhance seedling emergence and the speed of turfgrass establishment under deficit irrigation. Tests were performed with tall fescue (Schedonorus arundinaceus) and perennial ryegrass (Lolium perenne). Surfactant was applied directly to the seed using a rotary seedcoater at 0.1% by weight of seed. In the first experiment, germination was compared between seeds with a surfactant film coating (SFC) and untreated seeds in growth chambers at three different constant temperatures (10, 20, and 30 °C). For both species, the SFC decreased the time for seed germination, and improved germination synchrony, with the greatest treatment response at 10 and 30 °C compared with untreated seed. Application of a SFC did not influence FGP. In the second experiment, untreated and treated seed were compared in a grow-room study, with pots watered weekly to 70% of field capacity (FC). Perennial ryegrass density, cover, and aboveground biomass from the SFC were ≈47%, 48%, and 46% greater than untreated seed, respectively. Tall fescue density, cover, and aboveground biomass from the SFC seeds were ≈22%, 23%, and 28% greater than untreated seed, respectively. Overall these studies demonstrate that SFC can promote seed germination and also enhance turfgrass establishment under deficit irrigation.

Abstract:

Many frugivorous animals disperse seeds in their faeces (Corlett 1998, van der Pijl 1982), which may enhance the ability of secondary seed dispersers and post-dispersal seed predators to locate seeds (Andresen 2001, Chapman 1989, Feer 1999, Janzen 1982). By destroying and moving seeds these animals can radically alter the primary seed shadows generated by frugivorous animals and, consequently, have the potential to influence plant recruitment (Alcántara et al. 2000, Crawley 1992). Nevertheless, the influence of faeces on seed removal in South-East Asian forests has not previously been investigated and our knowledge currently comes from studies in Neotropical forests (Andresen 2001, Chapman 1989, Feer 1999, Janzen 1982).

Abstract:

Fusarium spp. are key pathogens in maize seeds and seedlings. The aim of this study has been to evaluate the effects of applying fungicides to maize seeds to increase the survival of seedlings and to enhance the early vigor and grain yield of the plants. The protective effects of 2-way (fludioxonil, metalaxil-M) and four-way (fludioxonil, metalaxil-M, azoxystrobin, thiabendazole) fungicide seed treatments were compared with an F. verticillioides seed infected control in 11 field trials carried out in North Italy. A second study focused on the impact F. verticillioides and F. graminearum seed-borne infection on plant growth and on the possible advantages of applying the previously reported seed dressing. The seed dressing increased the plant density, vigor during the whole vegetative growth cycle for all the production situations, and grain yield. F. verticillioides led to a higher seedling mortality than F. graminearum, while both species reduced plant growth and delayed the flowering date. Seed-borne infection has an important impact on both the population and vigor of maize plants. The four-way fungicide enhanced both the defense of the seedlings and the vigor of F. verticillioides infected plants, which in turn resulted in a significant improvement in grain yield, compared to a conventional two-way fungicide.

Abstract:

Botanicals are part of the bioresources for sustainable growth of food crops, however, some botanicals have been neglected. This study investigates the potential effects of neglected botanicals on selected underutilized food crops (millet, sorghum and sesame) in Nigeria. Blotter technique and soil inoculation methods were used to evaluate the best botanicals that could be employed to enhance seed germination (SG) and seedling growth of underutilized food crops. With the exception of Newbouldia laevis, other botanicals enhanced seed germination of all tested crops. Ficus asperifolia and Parquetina nigrescens significantly (p<0.05) enhanced the radicle length (RL) while the plumule length (PL) remained unaffected. Specifically, observation shows that Newbouldia laevis completely inhibited sesame seed germination and seedling growth while Parquetina nigrescens enhanced millet height and sesame number of leaves. Generally, the effect of the botanicals on each crop was specific. Thus, these neglected botanicals stand the chance to enhance and sustain seedlings of underutilized food crops in Nigeria. Further study would be carried out to uncover the chemical components in the tested botanicals.

Abstract:

A study was carried out to evaluate the effect of solid matrix priming of seeds on emergence (%), growth and fruit yield characters of bitter gourd (Momordica charantia L.) cultivar ‘Solan Hara’. The Experiment comprised of two vigour groups of seeds viz., ‘V1’ (High vigour seeds) and ‘V2’ (72 hours accelerated aged seeds/low vigour seeds) and five seed priming treatments viz., ‘P1’ (Solid matrix priming with Cocopeat), ‘P2’ (Solid matrix priming with Perlite), ‘P3’ (Solid matrix priming with Vermiculite), ‘P4’ (Seed soaking in water), ‘P5’ (Control -Without treatment).Investigation proved that low vigour seeds were inferior in respect of high vigour seeds in terms of seed physiological quality, emergence, growth and yield characteristics. Seed priming with Perlite for 72 hours proved its potential over other priming treatments, seed soaking and control (non-primed seeds) in both high vigour and low vigour seeds for agronomic attributes under study. High vigour seeds primed with Perlite ‘V1P2’ was found to be the best treatment for most of the traits understudy recording highest total field emergence (76.60%), fruit yield per plot (16.12 Kg) and per hectare (250.35 q). Similarly, Low vigour seeds primed with Perlite also recorded enhanced and improved total field emergence (73.83%) fruit yield per plot (9.28 Kg) and per hectare (143.26 q) compared to other low vigour treated and non treated seeds. From the present investigation it was inferred that that the extent of improvement w.r.t. attributes studied was more in low vigour seeds (V2) and seed priming with solid matrix carrier ‘Perlite’ can be used as a beneficial pre-sowing treatment to enhance the seedling emergence, growth and yield characteristics in bitter gourd.

Abstract:

Fungal endophytes mainly belong to the phylum Ascomycota and colonize plants without producing symptoms. We report on the isolation of seed-borne fungal endophytes from Phragmites australis (common reed) that were ascribed to the genus Stagonospora. Nested polymerase chain reaction (PCR) assays revealed that a Stagonospora sp. regularly colonized reed as shown for a period of three years. In spring, it was only detected in roots, whereas in autumn, it could frequently be found in all organs, including seeds. Microcosm experiments revealed that seeds harbored viable propagules of the fungus that colonized the developing germling, indicating vertical transmission. Endophytic growth was confirmed by immunofluorescence microscopy, reisolation of the fungus after surface sterilization, and PCR. Aseptic microcosms were established for studying fungal contributions towards host vitality. Several Stagonospora isolates enhanced reed biomass. Seed-borne endophytic Stagonospora spp. thus can provide improved vigor to common reed, which could be most important when seed-derived germlings establish new reed stands.

Abstract:

Cultivation of onion and onion-like crops has become a challenge in the context of climate change and innovative solutions are needed to support breeders as well as farmers, starting from the crucial issues of seed quality. Seed priming is routinely used to enhance germination performance and seedling resilience. Although common for radish, tomato, carrot or head cabbage seeds, the technique has been less popular for onion-like crops. This review provides a state-of-the-art picture of the scientific and technological advances that have so far contributed to enhance seed germination and vigour in onion-like crops. A brief description of the different types of priming approaches is provided whereas attention is focused on the following: (i) the impact of seed priming in terms of improved germination, seedling development and resilience to environmental stresses; (ii) the concept of seed quality hallmarks translated from model plants to the genus Allium; (iii) the drawbacks that currently impair the fully exploitation of seed priming in this specific sector of the agrifood chain.

Full text

Abstract:

Seed priming is a presowing technique in which seeds are moderately hydrated to the point where pregermination metabolic processes begin without actual germination. Seeds are then redried to near their actual weight for normal handling. Seeds can be soaked in tap water (hydropriming), aerated low-water potential solutions of polyethylene glycol or salt solutions (KNO3, KH2PO4, KCl, NaCl, CaCl2 or MgSO4; osmopriming), plant growth regulators, polyamines (hormonal priming), plant growth-promoting bacteria (biopriming), macro or micronutrients (nutripriming) or some plant-based natural extracts. Here, we review: (1) seed priming as a simple and effective approach for improving stand establishment, economic yields and tolerance to biotic and abiotic stresses in various crops by inducing a series of biochemical, physiological, molecular and subcellular changes in plants; (2) the tendency for seed priming to reduce the longevity of high-vigour seeds and improve the longevity of low-vigour seeds; (3) the advantages of physical methods of seed priming to enhance plant production over conventional methods based on the application of different chemical substances; (4) the various physical methods (e.g. magneto-priming and ionising radiation, including gamma rays, ultraviolet (UV) rays (UVA, UVC) and X-rays) available that are the most promising presowing seed treatments to improve crop productivity under stressful conditions; and (5) effective seed priming techniques for micronutrient delivery at planting in field crops. Seed priming as a cost-effective approach is being used for different crops and in different countries to improve yield, as a complementary strategy to grain biofortification and in genetically improved crop varieties to enhance their performance under stress conditions, including submergence and low phosphorus. Some of the challenges to the broad commercial adaption of seed priming include longevity of seeds after conventional types of priming under ambient storage conditions and a lack of studies on hermetic packaging materials for extended storage.

Abstract Seeding is the most important and quite challenging stage in seed/TSS cultivation. Plant growth regulator (PGR) seed priming has the potential to enhance the quality of TSS seedlings. The research had been conducted in the greenhouse of Agriculture Faculty, UGM, from February to April 2020. The factorial treatments of shallot cultivars (Tuk-Tuk, Lokananta and Sanren) and seed treatments (soaking seed with GA3 100 ppm and NAA 50 ppm for 12 hours and untreated seeds as control) were assigned in the RCBD with four replications. Each experimental unit was consisted of 728 seeds per cultivar. Both treated and untreated seeds were sown in soil blocks. The data were analyzed using ANOVA and continued with Tukey HSD procedure at α=0.05. The results showed that PGR priming on seeds significantly increased the germination percentage, plant height, leaf number, leaf area, and hypothetical vigor index of the three cultivars at six weeks after sowing. However, there was no significant difference in the fresh weight and dry weight of seedlings. This research implied that soaking seeds in GA3 100 ppm and NAA 50 ppm for 12 hours could improve seed germination and TSS seedling growth. Additional fertilizers are perhaps needed in soil blocks to increase the effect of hormones on the seedlings.

Vermicompost or worm-worked wastes have been reported to enhance seedling germination and growth during plug production. The objective of this project was to examine the effects of vermicompost on germination of a herbaceous perennial having varying viability in coir-based container media. Seeds of Echinacea purpurea (Purple Coneflower) collected from field-grown plants in 1998 and 1999 were considered low- and medium-viability seeds, respectively. A third group of seeds was purchased from a major seed company and was considered to have high viability due to optimal storage conditions. “Ragdoll” germination tests resulted in the following viability ratings: low (1%), 1998; medium (67%), 1999; and high (79%), purchased seed. The three sources of seed were planted into coir-based media. Vermicompost was incorporated into the media at 10% by volume. The control media did not have vermicompost added. Twelve days after project initiation seeds sown into media containing vermicompost had 73% and 90% greater germination than control media for the 1999 and purchased seed. At the project conclusion, 24 days after initiation, seeds sown into media containing vermicompost had 23% and 42% greater germination than the controls for the 1999 and purchased seed. The 1998 seed had 5% germination after 24 days compared to 1% for the control. The addition of vermicompost could be used as a method to increase germination rate and percentage of seeds having lower viability.

Abstract:

The current study was aimed to evaluate the seed priming potential of AGE (aqueous garlic extracts) to enhance seed germination and early seedling growth of eggplant. Different concentrations (100, 200, and 300 µg mL−1) of AGE were evaluated along with methyl jasmonate (MeJA) and salicylic acid (SA), plant growth regulators with reported seed priming potential whereas, water was taken as a control treatment. Eggplant seeds were primed for 4-, 8-, and 12-h and seed germination traits such germination rate index, germination percentage, mean germination time, and early seedling growth traits such as fresh and dry weights, root, and shoot lengths were observed. Moreover, plant antioxidant enzymes activities and lipid peroxidation levels, soluble protein contents and reactive oxygen species were monitored to establish the stimulatory/inhibitory effects of the treatments. Our results indicate priming potential of AGE, SA, and MeJA to enhance seed germination and early seedling growth in eggplant and the effects were obvious in various morphological and physiological traits. Seed priming significantly altered the antioxidant enzymes activities such as superoxide dismutase (SOD), and peroxidase (POD) with alteration in the reactive oxygen species (ROS). Interestingly, priming duration also affected the bioactivity of these chemicals because seed priming with 300 µg mL−1 AGE for 4 h had a positive influence, however, prolonged exposure to the same concentration inhibited the seed germination process and induced oxidative stress on the seedlings with elevated levels of malondialdehyde (MDA) content. We propose AGE seed priming as a bio-stimulant to enhance seed germination and early seedling growth in eggplant, and the results hence lay the foundation for the preparation of garlic-based compounds to improve vegetables production under plastic tunnels and greenhouse production units.

Abstract:

Trichoderma spp. are endophytic plant symbionts that are widely used as seed treatments to control diseases and to enhance plant growth and yield. Although some recent work has been published on their abilities to alleviate abiotic stresses, specific knowledge of mechanisms, abilities to control multiple plant stress factors, their effects on seed and seedlings is lacking. We examined the effects of seed treatment with T. harzianum strain T22 on germination of seed exposed to biotic stress (seed and seedling disease caused by Pythium ultimum) and abiotic stresses (osmotic, salinity, chilling, or heat stress). We also evaluated the ability of the beneficial fungus to overcome physiological stress (poor seed quality induced by seed aging). If seed were not under any of the stresses noted above, T22 generally had little effect upon seedling performance. However, under stress, treated seed germinated consistently faster and more uniformly than untreated seeds whether the stress was osmotic, salt, or suboptimal temperatures. The consistent response to varying stresses suggests a common mechanism through which the plant–fungus association enhances tolerance to a wide range of abiotic stresses as well as biotic stress. A common factor that negatively affects plants under these stress conditions is accumulation of toxic reactive oxygen species (ROS), and we tested the hypothesis that T22 reduced damages resulting from accumulation of ROS in stressed plants. Treatment of seeds reduced accumulation of lipid peroxides in seedlings under osmotic stress or in aged seeds. In addition, we showed that the effect of exogenous application of an antioxidant, glutathione, or application of T22, resulted in a similar positive effect on seed germination under osmotic stress or in aged seed. This evidence supports the model that T. harzianum strain T22 increases seedling vigor and ameliorates stress by inducing physiological protection in plants against oxidative damage.
