Abstract:
Soybean lines lacking lipoxygenase (LOX) activity were compared with soybean lines having LOX activity for the ability to support growth and aflatoxin B1 production by the fungal seed pathogen Aspergillus flavus. Whole seeds, broken seeds, and heat-treated (autoclaved) whole seeds were compared. Broken seeds, irrespective of LOX presence, supported excellent fungal growth and the highest aflatoxin levels. Autoclaved whole seeds, with or without LOX, produced good fungal growth and aflatoxin levels approaching those of broken seeds. Whole soybean seeds supported sparse fungal growth and relatively low aflatoxin levels. There was no significant difference in aflatoxin production between whole soybean seeds either with or without LOX, although there did seem to be differences among the cultivars tested. The heat treatment eliminated LOX activity (in LOX+ lines), yet aflatoxin levels did not change substantially from the broken seed treatment. Broken soybean seeds possessed LOX activity (in LOX+ lines) and yet yielded the highest aflatoxin levels. The presence of active LOX did not seem to play the determinant role in the susceptibility of soybean seeds to fungal pathogens. Seed coat integrity and seed viability seem to be more important characteristics in soybean seed resistance to aflatoxin contamination. Soybean seeds lacking LOX seem safe from the threat of increased seed pathogen susceptibility.

Abstract:
Seed production in the family Cucurbitaceae is more complicated than in dry-seeded grain crops because seeds mature within a moist fruit and are often held at high moisture content for several weeks before seed harvest. Muskmelon (Cucumis melo L.), a member of this family, was used as a model system to contrast seed development with crops that are dry at maturity. A detailed time course for `Top Mark' fruit and seed development is presented based on previous studies. In muskmelon fruit, precocious germination is inhibited osmotically by the low water potential of the surrounding fruit tissue. Muskmelon seeds exhibit primary dormancy that affects viability very early in development but has a greater effect on seed vigor and is removed by afterripening during dry storage. Osmotically distended or fish-mouth seeds are dead seeds that occur in cucurbit seed lots after aging kills the embryo without disrupting the semipermeable endosperm that completely surrounds and protects the embryo. Cucurbit seed crops should be harvested before the onset of fruit senescence to prevent aging of the seeds inside. Open-pollinated cucurbit seed crops are frequently once-over mechanically harvested. Mechanical harvesting combines seeds from many stages of development into a single seed lot, which may adversely affect quality and increase seed to seed variability. Hand harvesting cucurbit fruit at the optimal stage of development could improve seed quality in some instances but is more costly and time consuming and would increase production costs.

Abstract:
The environment that seeds experience during development, storage, and planting significantly affects seed vigor. Yet, relatively few studies have focused on how environment during seed development affects seed vigor. Our objective was to compare vigor of seeds developed in summer vs. winter. Lettuce (Lactuca sativa L.) seeds from six cultivars were developed in summer and winter at Yuma, Ariz. Seed vigor of these seedlots was compared using field plantings and growth chambers (at 20, 25, 30, and 35C). Seed vigor was greater for seed produced during summer than for that produced during winter, based on greater field emergence, higher germination percentages, and longer roots. These seedlot differences in vigor were greatest at 35C. Another way to estimate seed vigor is by ion leakage from seeds. Fewer ions leaked from seeds produced in summer than from those produced in winter. Thus, lettuce seed is more vigorous when produced in summer than in winter, and ion leakage is a good indicator of that vigor.

Abstract:
Red fescue (Festuca rubra L.) it is one of the most popular crops for creating lawns of various types and as a component of meadow and pasture poly-species mixtures of long-term use. The volume of domestic production of seeds of this crop is less than 2% of the total sales of seed material on the Russian market. The wide expansion of imported seeds of foreign-selected varieties to the domestic market sharply raises the question of the need to develop seed production of this crop in Russia. To do this, it is necessary to intensify breeding for the development of new varieties of red fescue, the development of zonal technologies for cultivating them for seeds. Analysis and generalization of research results shows that when using a set of optimal agricultural techniques, it is possible to consistently receive seed collections of more than 0.4 t/ha. This level of seed yield ensures high profitability of production and recoupment of energy costs. Assessment of the energy efficiency of technologies for cultivation of red fescue pasture-lawn ecotype shows that the total energy consumption per 1 ha of seed was 17.7 GJ, per 1 kg of seeds – 68.2 MJ. Due to the increase in yield by 44.4% and the use of energy-saving techniques, energy savings per 100 kg of seeds amounted to 25.6%. The energy assessment showed that as a result of harvesting seed crops by direct threshing in the optimal time frame, total energy costs decreased by 19%, and energy consumption for fuel – by 29%.

Abstract:
The growing of transplants in plug cell trays is the primary method of producing brassica transplants in many countries. Seed quality is an important aspect to achieve success in transplant production. Seed size may affect seed performance, seedling growth and development of brassica transplants. Seeds of cauliflower (`Vitoria de vero') and cabbage (`Unio') from Embrapa Vegetables were used in this study. During seed conditioning, seeds were classified using round screens generating three (>1.5, 1.5-2.0, and 2.0-2.5 mm) and four (>1.5, 1.5-2.0, 2.0-2.5, and < 2.5 mm) seed size categories, for cauliflower and cabbage, respectively. The original seed lot was used as control. Seed weight increased with seed size. Seed germination (laboratory) and seedling emergence (greenhouse) were not affected by seed size. In both species, root and shoot weight, and leaf area, measured 30 days after seeding, in greenhouse conditions, increased with seed size. Also, transplants from larger seed size resulted in a significantly higher root weight, shoot weight, and leaf area relative to the original (control) seeds. The results indicate that, overall, an adequate seed conditioning improve brassica transplant quality.

Abstract:
The main problems in the development of seed production and inter-subject interactions in seed production are: the high level of import dependence of Russian agriculture on seeds of a number of crops; fragmentation of the system of domestic seed production; a relatively low level of selection work for some types of agricultural crops and the competitiveness of seeds of domestic selection; low rates of renewal of the technical and technological base of breeding centers and seed farms; shortage of highly qualified personnel in the field of breeding and genetics of agricultural crops and seed production; insufficient level of state support for seed producers and incentives for agricultural producers to use elite seeds and hybrids of domestic selection. The article also proposes a set of measures to modernize the existing seed production system and ensure the stability of its inter-subject relations, which will provide the necessary conditions for increasing the level of efficiency of the seed production system and solving the problems identified in the Doctrine of Food Security of the Russian Federation.

Abstract:
Potato is an important food and cash crop globally and faces many challenges in Pakistan. These challenges include issues with soil fertility, pest and disease pressure and shortages of high-quality seed potatoes. The scarcity of high-quality seeds is a massive hassle in Pakistan. Farmers in Pakistan, often reuse their seeds or obtain them from informal sources. This practice leads to increased seed quality deterioration and tuber-borne diseases, resulting in decreased yields. To address this situation, aeroponic techniques can effectively meet this challenge. Aeroponics is a novel technique for producing high-quality seed potato, aiming to address the challenge of seed production. Aeroponic techniques are commercially practised in many countries. Thus, in this review, we have highlighted the importance of aeroponic technology and how this technique can help uplift/boost up the seed potato production system in Pakistan. The overview concludes that aeroponic seed production offers numerous benefits, including improved yields, and resistance, even as keeping natural resources. Despite the challenges, the evaluation indicates that the implementation of aeroponic seed production technology in Pakistan may offers a promising and sustainable technique for seed potato production in Pakistan.

Abstract:
This paper aims at presenting the structure of varieties and the evolution of consumption of seeds for main cereal crops. Analyzing the number of varieties and hybrids, it may be noticed that there is a growing trend. In Romania, the quantities of seeds used were variable, depending, on the one hand of the importance and expansion of the crop, and, on the other hand, on the records existing in the seed chain. For Romania, looking at the overall practices applied in relation to seed utilization a growing trend was noticed with respect to using seeds for wheat crops, but also a drop of barley and maize crops, besides the annual fluctuating consumption levels. By correlating the factors (areas and amounts of seeds) with production that may be obtained a growing trend for wheat and barley was noticed and a decreasing trend for maize.

Abstract:
The reproductive biology of western white pine ( Pinus monticola Dougl. ex D. Don) at the Saanich seed orchard (SSO; a coastal seedling seed orchard) and the Kalamalka seed orchard (KSO; an interior clonal seed orchard) is described. Seed-cone development and morphology determine seed potential and affect filled seed production. Seed potential was high, commonly over 200 seeds per cone and filled seeds per cone averaged 50–60 at both orchards in 1999 from open pollinations combined with operational supplemental mass pollinations (OP-SMP). Filled seeds per cone at SSO in 2004 averaged 115 with open pollinations and OP-SMP. About 30% of ovules aborted before pollination. Another 25% aborted probably because of self-incompatibility at fertilization. Seed efficiency (SEF) was only 5% at KSO with open pollination but increased to 30% with OP-SMP. SEF was the same at SSO with or without OP-SMP. Reproductive success was very low at KSO without OP-SMP but increased to about 10%, similar to that of SSO, with OP-SMP. The optimal time for control pollinations was at cone stages 4 and 5 and optimal amount of pollen per pollination bag was 0.3–0.4 mL. Western white pine is a very good seed producer and can be easily managed in seed orchards to give very high seed production per cone and per tree.

Abstract:
The use of native species has been increasingly advocated to achieve the sustainable recovery of degraded areas and in Europe considerable effort has also been invested into grassland restoration using such species. However, little attention has been paid to the evaluation and significance of aspects of the seed quality of native species, which may have implications for the success of these projects. The current research examined three aspects of seed quality in the context of commercial seed production and the use of seed in the restoration of vegetation. Firstly, the effect of plant and seed responses to a range of maternal environments during seed production was examined using the perennial herb Primula vulgaris as a model. Different shading conditions, imposed in the field over two seasons during seed maturation, produced a range of red : far-red light ratios (R:FR) received by the parent plants. The competitiveness of P. vulgaris plants grown in the different environments was evaluated though measurements of plant gas exchange, membrane integrity, leaf chlorophyll concentration, photosynthetic efficiency, specific leaf area and above ground plant biomass; the weight and number of seeds produced was also assessed. This revealed the phenotypic plasticity of P. vulgaris and that growth, competitiveness and seed production were favoured in shaded conditions. Subsequent germination of the harvested seeds at five temperatures (5 – 25oC) and high to low R:FR revealed that there was no effect of shading of the maternal plant on seed quality, either the rate of germination or final germination. In addition, the maternal environment did not affect the subsequent light and temperature requirements for germination. An increased germination capacity in response to a higher R:FR for all maternal environments suggested the potential for seedling establishment under vegetative shade only in the presence of canopy gaps. Secondly, the germination potential and dormancy-breaking requirements of 113 commercially available seed lots of eight European native species was examined. This revealed a wide range in the germination of seed lots within a species and surprisingly low levels of dormancy. Alternative and more rapid methods to the routine germination methods were subsequently developed. A tetrazolium testing protocol was developed that predicted germination of each of the eight native species in only two days. In addition, the electrical conductivity (EC) of seed soak water provided a quick and inexpensive measure of final germination in a day and even within a day. However, its application may be limited to large and exalbuminous seeds, such as Cyanus segetum, which are dominated by the embryo and lack an endosperm. The third aspect of seed quality investigated was its impact on establishment and growth of Rhinanthus minor, a hemi-parasite. Ten seed lots from commercial sources were sown in the field and their germination characteristics were investigated in the laboratory. Field emergence was influenced by both the radicle emergence of each lot and the mean germination time, which is indicative of seed vigour. Seeds from four lots with >90% radicle emergence were then germinated to radicle emergence and sown in pots alongside plants of two host species, Lotus corniculatus and Holcus lanatus. Plant establishment, height and flowering density were evaluated for the hemi-parasite, while plant biomass was measured for both R. minor and its host. A longer lag period (lower vigour) was associated with higher levels of seedling mortality and lower plant vigour, in terms of plant height and biomass accumulation, and was also reflected in the parasitic impact of the seed lots, with the least vigorous seed lot having no impact on the biomass of its host, Lotus corniculatus. These observations highlight that the quality of the seed is significant to the potential use of R. minor as a hemi-parasite.

Abstract:
Sweet basil (Ocimum basilicum L.) is a warm season herb usually propagated from seeds. Establishment of basil is difficult as seed germination may be limited, particularly during field seeding at cold soil temperatures. The germination of six cultivars (\'Italian Large Leaf\', \'Italian Large Leaf\' 35X, \'Nufar\', \'Genovese\', \'Genovese Compact Improved\' and \'Aroma 2\') of sweet basil seeds were tested on a one dimensional thermo-gradient table over temperatures ranging from 0 to 50"C. At temperatures below 20"C, germination among cultivars was more variable and the mean time to germination (MTG) increased to greater than 25 days for some cultivars. Germination declined sharply and had a sudden termination at high temperatures above 40"C for all six cultivars.  There were statistical differences among the cultivar base temperatures, which ranged between 10.1 and 13.3"C. The optimal and ceiling temperatures for germination were similar and did not differ statistically among the cultivars compared in this study. The average optimal temperature for all cultivars was 35 ± 0"C, while the average ceiling temperature was 43 ± 1.3"C. Stored seeds (> 5 years) had lower seed vigor and lower germination percentage, also lower ceiling temperature compared with the fresh seeds of the same cultivar (\'Italian Large Leaf\'), but the base temperatures were the same for both new and old seeds. Sweet basil (Ocimum basilicum L.) seeds produce a thick layer of mucilage around the pericarp within minutes after hydration. Mucilage is most prevalent among plant species adapted to surviving in arid sandy soils, though its significance in determining ecological fitness is unclear. The mucilage produced by seeds is reported to be composed of cell-wall polysaccharides that are deposited in testa pericarp cells during development. In this study, sweet basil seeds were examined using light and environmental scanning electron microscopy. The mucilage of basil seeds is held together by columnar structures that unfolded from the pericarp and helped hold and stabilize the mucilage to the outer surface. The mucilage was removed using diluted hydrochloric acid to compare performance of seeds with and without mucilage. Mucilage removal did not inhibit seed germination under ideal laboratory conditions but decreased the water content of seeds significantly. The water content of intact seeds was almost 4 times greater than seeds without mucilage. Mucilage enabled seeds cling to an incline board set to a steeper angle than seeds without mucilage. The fully hydrated seeds approached zero water potential, so the mucilage did not prevent seeds from fully hydrating. Soil (media) germination testing showed the seeds with mucilage had higher germination percentage than the seed without mucilage on several different types of media. Seeds with mucilage also had higher survival percentages after 10 days on different types of media. Basil seeds mucilage acts as a reservoir to hold loosely bound water at high water potential so it is available for seed germination and early seedling development.

Abstract:
The analysis of the main reason for the loss of the birdsfoot trefoil seed yield — destruction of beans. It was found that the biological yield of seeds reached its maximum values in the range of 308–320 kg/ha when 69–93% of the beans were browned, or 35–50 days after the beginning of flowering. The optimal period of direct threshing with pre-desiccation of the herbage with Reglon Super at a dose of 4 l / ha is a period of Browning of about 70% of the beans. This ensures the highest actual seed harvest of 191–206 kg/ha.

Abstract:
On sod-podzolic medium-loamy soils of the Central Non-Chernozem region of Russia with an average availability of mobile forms of phosphorus and an average close to low potassium content, high efficiency of using potash fertilizer together with phosphorus on birdsfoot trefoil seed crops was established. Effective doses of phosphorus-potassium fertilizers, providing an increase in seed yield in the first year by 42–47% and, according to the aftereffect, in the second year by 17–33%, are the application of P30–60K90–120. Keywords: Birdsfoot trefoil (Lotus corniculatus L.), seed herbage, phosphoric and potash mineral fertilizers, yield, seeds, sowing qualities.

Abstract:
A characteristic property of legumes is the formation of hard-stone seeds. To use such seeds for sowing, it is necessary to carry out measures to increase their seeding indicators. The article provides an overview of methods of pre-sowing preparation of seeds, priming (Seed Priming). The harvest of Birdsfoot trefoil (Lotus corniculatus L.) can contain up to 90% or more hard-stone seeds. Mechanical priming of hard-stone seeds of Birdsfoot trefoil increases their germination energy and field germination.

Israel, Alvaro, and John Merrill. Production of Seed Stocks for Sustainable Tank Cultivation of the Red Edible Seaweed Porphyra. United States Department of Agriculture, 2006. http://dx.doi.org/10.32747/2006.7696527.bard.

Abstract:
Porphyra species (commonly known as ‘nori’ or ‘purple laver’) are edible red seaweeds rich in proteins, vitamins and other highly valued biogenic compounds. For years Porphyra has been cultured using seeded nets extended in the open sea, and its biomass consumed primarily in the Far East. While demands for international markets have increased steadily at an average of 20% per year, supplies are on the verge and not expected to meet future demands. Alternatively, land-based cultivation of seaweed has become attractive in the mariculture industry since (1) important growth parameters can be controlled, (2) is environmentally friendly and (3) perfectly matches with integrated aquaculture leading to sustainable, high quality products. During the last few years a tank cultivation technology for Porphyra has been developed at the Israeli institution. This technology is based on indoor production of asexual spores and their subsequent growth to 1-2 mm seedlings. The seedlings are then transferred to outdoor tanks and ponds when seawater temperatures drop to 20 °C, or below, and days become shorter during winter time. However, the current technology efficiently serves only about 100 m2 of ponds during one growth season. In order to produce seedlings in sufficient amounts, it is critical to address both technical and biological aspects of seedling production, securing optimal up-scale to commercial-size cultivation farms. We hypothesize that massive production of spores is related to thalli origin, thalli age and sporulation triggers, and that seedling survival and their subsequent growth potential is determined by the seawater quality and overall indoor growth conditions imposed. A series of bio-reactors were constructed and tested in which spore release and spore growth were separately studied. The main assessment criteria for optimal viability of the seedlings will be by determining their electron transport rate using PAM fluorometry and by subsequent growth and biomass yields in outdoor ponds. Altogether the project showed (1), controlled sporulation is possible in big outdoor/growth chamber settings provided initial stock material (small frozen seedlings) is at hand, (2), contamination problems can be almost completely avoided if stock material is properly handled (clean as possible and partially dehydrated prior to freezing), (3), spore release can significantly be enhance using high nutrient levels during thawing for P. yezoensis and P. haitanensis, but not for P. rosengurttii, (4), PAM fluorometry is an efficient tool to estimate growth capacity in both seedlings and juvenile thalli. The BARD funding also served to explore other aspects of Porphyra biology and cultivation. For example, the taxonomical status of Porphyra strains used in this study was defined (see appendix), and the potential use of this seaweed in bioremediation was well substantiated. In addition, BARD funding supported a number of opportunities and activities in the Israeli lab, direct or indirectly related to the initial objectives of the project such as: additional molecular work in other seaweeds, description of at least 2 new species for the Israeli Mediterranean, and continuous support for the writing of a book on Global Change and applied aspects of seaweeds. The technology for Porphyra cultivation in land-based ponds is readily available. This study corroborated previous know-how of Porphyra growth in tanks and ponds, and yet offers important improvements regarding seedling production and their handling for successful cultivation. This study supported various other activities opening additional important issues in the biology/cultivation/use of Porphyra and other seaweeds.
