Abstract:
The work presents the evaluation results of the viability of oat and barley collection varieties during storage in the laboratory conditions at the temperature of 20-25o C. Seed storage covered the period of 2006-2017. The research included 24 varieties of barley and 29 varieties of chaffy oats of domestic and foreign breeding collection. The seeds were stored in different packaging materials such as standard paper package; glass bottles of 0.25 liter and plastic bottles of 0.5 liter. The initial seed moisture content was 8.5-9.0 per cent. The varieties were divided into groups taking into account the initial laboratory seed germinating ability. For oats the fi rst group included 10 varieties with initial germination of 96-99%; the second group included 12 varieties with initial germination of 91-95%; the third group included 7 varieties with initial germination of 86-90%. For barley the fi rst group consisted of 5 varieties with initial germination of 91-99%; the second group consisted of 10 varieties with initial germination of 81-90%; the third group consisted of 9 varieties with initial germination of 71-80%. Determination of seed quality was carried out in 7 and 11 years’ time. The initial moisture content of seeds remained without signifi cant changes in all packaging types during the storage period of 11 years. It was also noted that germination of oat and barley seeds during 7 years of storage did not differ in any type of package. The average value in all three groups of oats was 93.2%. After 11 years of storage, germination of oat differed a little, depending on the type of package. In a paper bag it was 80.4%; in a glass bottle – 88.2%; in a plastic bottle – 85.1%. The average initial germination of three groups of barley in 7 years’ time of storage was 84.7%. After 11 years of storage, germination of barley was 53.2% in a paper bag; 63.3% in a glass bottle; 61.8% in a plastic bottle It was revealed that oat and barley seed germination in 7 years’ time did not differ in any type of package. After 11 years, germination of oats was 5.8% higher, and germination of barley was 8.6% higher in a sealed plastic bottle than in a standard paper bag. Differences in seed germinating ability between the glass and plastic bottles were not observed.

Abstract:
Barley seed sensitivity to water and anoxia was tested. Standard germination, mean time of germination (MTG), germination in sand wetted by water to 100% water capacity (anoxia) or by hydrogen peroxide (wet conditions without anoxia), germination in 0.75% hydrogen peroxide and laboratory emergence (15 and 20&deg;C) were evaluated. Barley seed responds sensitively to stress conditions during germination. Significant germination decrease was found in abundance of water. Percentage of reduction depends on the variety and on the year of seed production. Extreme values of water sensitivity are in interval 4&ndash;90%. At wetted sand by 0.75%, solution of H<sub>2</sub>O<sub>2</sub> the germination was significantly less reduced. That means that barley seed is very sensitive to oxygen deficiency above all and is less injured by quick imbibition. Heterogeneity in seed vigour was demonstrated in laboratory emergence tests. Quick test of germination in 0.75% hydrogen peroxide deserves attention for its high correlation coefficient with the seed laboratory emergence. The results significantly demonstrate a&nbsp;higher sensitivity of deteriorated seed to germination in abiotic stresses conditions. Variability in speed of germination is increasing, which unfavourably extends the mean time of germination.

Abstract:
Ozone is widely used to control pests in grain and impacts seed germination, a crucial stage in crop establishment which involves metabolic alterations. In this study, dormancy was overcome through after-ripening (AR) in dry barley seed storage of more than 4 weeks; alternatively, a 15-min ozone treatment could break the dormancy of barley immediately after harvest, with accelerated germination efficiency remaining around 96% until 4 weeks. Headspace solid-phase microextraction (HS-SPME) and liquid absorption coupled with gas chromatography mass spectrometry (GC-MS) were utilized for metabolite profiling of 2-, 4- and 7-day germinating seeds. Metabolic changes during barley germination are reflected by time-dependent characteristics. Alcohols, fatty acids, and ketones were major contributors to time-driven changes during germination. In addition, greater fatty acids were released at the early germination stage when subjected to ozone treatment.

Abstract:
Abstract Seed aging is the main problem of seed storage. Changes of enzyme activity and reduction of seedling growth are consequence of seed deterioration. An experiment was conducted to evaluate the effects of accelerated aging on germination indexes and enzyme activity of barley seeds. Seeds were incubated in closed plastic boxes for the accelerated aging treatments at 41°C. Three accelerate aging regimes were performed by placing seeds at 41°C and relative humidity (RH) of 90-100 % for 0, 4 and 8 day periods. Our results showed that increasing aging duration resulted higher reduction in germination percentage, germination index, mean time to germination, normal seedling percentage, catalase and ascorbate peroxidase. The highest germination percentage, germination index, normal seedling percentage and enzyme activity were achieved in control conditions (0 day of aging). Under aging conditions, germination percentage, means time to germination, germination index, normal seedling percentage and enzyme activity decrease significantly. Also, our results indicated that seed aging is related to decrease of enzymes and may contribute to low germination efficiency. The general decreases in enzyme activity in the seed lowers the respiratory capacity, which in turn lowers both the energy (ATP) and assimilates supply of the germinating seed, also decrease in antioxidant enzymes is linked to an increased accelerated ageing and decreased germination characteristics. Subsequently, proposed a positive relationship between antioxidant enzyme capacity and the vigour of the seed

Abstract:
AbstractSoil salinity is one of the major abiotic stresses affecting seed germination, crop growth and productivity. In this study, seeds of three wheat (Triticum aestiveum L.) and three barley (Hordeum vulgare L.) cultivars were treated with different concentrations of NaCl to investigate the effect of salt on seed germination physiology and metabolism through the characterization of seed germination pattern, gamma-aminobutyric acid (GABA) shunt metabolite accumulation [GABA, glutamate (Glu) and alanine (Ala)] and glutamate decarboxylase (GAD) expression using RT-PCR. A trend of decreasing germination percentage with increasing NaCl concentrations was observed. Under all salt stress treatments, data showed significant increase with positive correlation (r = 0.50–0.99) between abundance of GABA shunt metabolites and salt concentration in all wheat and barley cultivars for 5 days. Increased GABA content was associated with a small but significant increase in Ala and Glu content in all cultivars. In all NaCl treatments, the transcription of GAD in terms of RNA abundance showed a significant increase in all cultivars with positive correlation (r = 0.50–0.98). Data showed significant association between GAD RNA transcription and the response of germinating seeds to salt stress in terms of GABA shunt metabolite accumulation. The elevated expression of GAD under salinity suggests the need for elevated activity of the GAD-mediated conversion of Glu to GABA during seed germination, which provides alternative metabolic routes to the respiratory machinery, balancing carbon and nitrogen metabolism and osmolyte synthesis in germinating seeds of wheat and barley under salt stress.

Abstract:
The heat production of seeds during germination comes from metabolism as well as hydration. Previous studies either lack continuous measurements, or are based on samples composed of more than one seed, thus failing to characterize differences among the critical phases of germination. This study examines the potential of isothermal calorimetry to characterize water uptake and metabolism in single seeds. Seeds of malting barley (Hordeum vulgare L.) and winterfat [Krascheninnikovia lanata (Pursh) A.D.J. Meeuse & Smit], two species with contrasting seed size, structure, composition and selection history, were used to determine patterns of heat production rate by isothermal calorimetry during water uptake and germination. Embryos of malting barley contributed less than 4% of total seed weight, and metabolic heat production during Phase I of germination was negligible compared to that due to hydration. Embryos accounted for 74% of seed mass for winterfat, and the majority of heat produced in Phase I was due to metabolic heat release. The total heat production rate in Phase I decreased rapidly in malting barley due to slowing of hydration reactions, but increased gradually in winterfat due to an increasing metabolic rate. The heat production rate at the end of Phase II was about twice as high in malting barley as in winterfat. This indicates a higher metabolic activity for malting barley than for winterfat seeds during germination, which may have also contributed to the rapid increase in the heat production rate of malting barley seedlings during Phase III, compared to the gradual increase in heat production rate of winterfat. The comparison between excised embryos and intact seeds indicates that the covering tissues delay radicle emergence in malting barley, but not in winterfat, due to differences in seed structure between the two species.

Abstract:
The application of chemicals, such as fungicides for seed treatment, is one of the most reliable and perhaps most efficient measures for integrated preservation of crops, and its practicing has become a legal obligation for all seed producers. This investigation was carried out in the laboratory for seed quality and phytopathology of the Small Grains Research Center in Kragujevac. The objective was to establish the effect of fungicides on germination energy and seed germ inability (determined after treatments). Two varieties were tested due to a possibility of specific sensitivities of some varieties, so that the results acquired on one variety would not necessarily be valid for another one. Fungicides based on active ingredients from the triasol chemical group had different effects on the energy of germination of barley seeds. Applying Raxil S040-FS, the average germination of barley seeds was 79.3% for the variety Record, and 91.3% for the Grand variety. The variety Record achieved a lower value than the minimum for barley seed germination (88%) stipulated by the Rules on Seed Quality of Agricultural Crops. Regardless of barley type, the product Raxil S040-FS showed a statistically significant effect on the number of atypical seedlings and increase in the number of non-germinated seeds, compared to the control.

Abstract:
Seed priming methods have been used to increase germination and seedling establishment under different abiotic stress conditions. Seed priming was used in barley to increase seed germination and tolerance on stress exposure. Barley seeds were treated with various priming agents for different time and temperatures. The effect of priming was assessed on germination characteristics on subsequent exposure to drought (PEG-12 bar) stress for 7 days. Seed priming treatments significantly (p≤ 0.01) affected germination percentage (GP), normality seedling percentage (NSP), germination Index (GI), germination uniformity (GU), means time to germination (MTG), coefficient of velocity of germination (CVG), seedling vigor index (SVI) and coefficient of allometry (AC). Seed priming with gibberelic acid (GA), salicylic acid (SA), ascorbic acid (ASc), hydropriming (HP), osmopriming (OP) and combined treatments (CT) significantly (p≤ 0.01) increased germination characteristics, compared to the unprimed. Seed priming with concentrations 25, 50 ppm of GA for 15 h at 10°C, 25 ppm of SA for 12 h at 10°C, 50 ppm of ASc for 12 h at 15°C, treatment 16 h hydropriming at 10°C and -15 bar PEG for 24 h for osmopriming may be considered as optimal treatment for priming of barley seeds in drought stress conditions. In some cases, combined treatments are better than the separate treatments. Seed priming with PEG (potential -l5 bar PEG for 24 h at 10°C) was more effective in drought stress than the other treatments.

Abstract:
Abstract Allelopathy is the detrimental effect of one crop on germination or development of a plant of another species. A factorial layout within completely randomized design with four replications was used to survey the influence of barley extract on corn seeds. Treatments included plant organs extract (leaf, stem, root and total), and different barley extract densities (Nosrat cultivar) includes four levels of 0%, 25%, 50% and 100%. The influence of barley extract was significant on coleoptile weight, radicle weight, radicle length and coleoptile length. Plant organs had meaningful effect on germination rate, germination percentage, coleoptile weight, radicle weight, radicle length and coleoptile length. Among all experimental characteristics, coleoptiles length was influenced by interaction between barley extract and plant organ. Although, the highest germination rate and germination percentage was related to 25% and 100% of barley extract density, the maximum coleoptile weight, radicle weight, radicle length and coleoptiles length was related to control treatment (0%). Leaf extract has obtained the higher values of germination rate, germination percentage, coleoptile weight, radicle weight, radicle length and coleoptile length. Interaction between control treatment (0% plant extract) and stem extract had obtained the highest coleoptiles weight, radicle weight, radicle length and coleoptile length. Hence, from the obtained results, it can be concluded that the extracts of barley may have allelopathic influence on germination and seedling growth of corn.

Abstract:
Two seaweed suspensions, obtained from whole brown algae Ascophyllum nodosum (Linnaeus) Le Jolis (ANS), or lamina of Laminaria hyperborea (Gunn.) Foslie (LHS), were evaluated for their effects on seed germination and seedling growth of barley (Hordeum vulgare L.) and lettuce (Lactuca sativa L.). The seaweed suspensions (SWS) tested had mineral composition similar to that of fresh algae, and mineral concentrations at levels reflecting the dilution of the product during the manufacturing process. The activity of growth regulating substances found in the SWS were too low to be of physiological significance. When pre-germinated seeds were exposed to SWS at 10% or higher, radicle growth was inhibited both in barley and lettuce to a similar extent. The polyphenol content in ANS was found to be responsible for these effects in lettuce seedlings. For LHS unknown compound(s) were present in the supernatant, active only in the light. The compound(s) was(were) organic, heat labile above 60OC, degradable by microbial activity and likely not to be a protein. A growth promoting compound that increased lettuce cotyledon expansion in the light and hypocotyl elongation in the dark, was identified as potassium. Priming barley or lettuce seeds in SWS was beneficial, and adhering algal material provided additional nutrients to the seeds, compensating for leakage losses. Priming for 12 hours with a 24 hour re-drying period did not reduce seed viability, or increase the number of dead seeds or abnormal seedlings. When germinated under optimum laboratory conditions, the mean germination time of primed seeds, irrespective of initial seed vigour, was generally reduced. Priming in SWS was not superior to water treatments. However, seedling emergence and growth of barley under greenhouse conditions was promoted by priming with ANS, and was better than priming in water.

The potentisation process during which homoeopathic preparations are produced, raises the concern that these remedies have a placebo effect, since they contain no active molecule of the substance used to prepare them (in ultra high dilutions) by the time they are administered to a patient. Plant models therefore offer a more direct method of examining the efficacy of homoeopathically prepared solutions. This study investigated the effects of homoeopathic preparations of gibberellic acid on the germination of barley seeds (Hordeum vulgare L.) as measured by a germination index. The effects of GA3 at potencies of 4cH, lScH, 30cH and 200cH on germination rate and seedling development were tested on barley seeds of high-, medium- and low- vigour. The index used comprised the rate at which seeds germinated, which was the time it took for 50 percent of those seeds that did germinate, to germinate (i.e. Tso); seedling development experiments as assessed by taking final germination counts 7 days after start of imbibition, shoot and root lengths, and seedling dry mass. Biological activity of homoeopathically prepared GA3 at lScH was evident in medium vigour seeds, since this treatment resulted in significantly long root development. Highvigour barley seeds imbibed in GA3 (0.5 g L\xB7l ) were found to germinate the fastest of all treatment groups, and high-vigour seeds imbibed in homoeopathically prepared GA3 at 4cH, 30cH and 200cH, germinated faster than those seeds not receiving GA3 in any form (the control).

Abstract:
Abstract The response of barley seedlings was studied after gamma irradiation of seeds with doses in the range of 2-50 Gy. It was shown that stimulation of plant growth occurred in the dose range of 16-20 Gy. The influences of the dose rate, the quality of seeds and their moisture on the manifestation of radiation effects were investigated. We studied, under controlled conditions, the activities of metabolic and antioxidant enzymes and observed an increase in their activity in the range of doses that cause stimulation of seedling growth. We showed that changes in the balance among different classes of phytohormones were probably involved in the acceleration of plant growth after irradiation of seeds using stimulating doses. Gamma irradiation of barley seeds significantly influenced the development of plants during the growing season. After irradiation with stimulating doses, we observed a reduction in the duration of the initial stages of ontogenesis; the phase of full ripeness occurred 5-7 days earlier than in the controls. The manifestation of the effect of irradiation depended on the conditions in which the plants developed. During the growing season of 2014, which was a dry year, plants originating from the irradiated seeds showed an increase in the number of productive stems, which led to an increase in yield by 34-38%; during the optimal 2015 season, an increase in the number of grains per spike caused an increase in yield by 8-29%. Therefore, our field study has shown that at least some hormetic effects can occur in the field. Irradiation of seeds can increase field germination, stimulate the growth and development of plants and increase their resistance to unfavourable environmental conditions. A more complete understanding of the underlying mechanisms of hormesis is needed to exploit its potential benefits in crop production.

Abstract:
When improving agricultural technologies, considerable attention should be paid to the use of organic fertilizers, which involves the use of humic and fulvic acids. This will reduce the use of mineral fertilizers and increase the yield of agricultural products, as well as grow environmentally friendly products. Justification of the use of organic fertilizers to stimulate plant growth requires a preliminary study of their action under laboratory conditions. The article analyzes the wide application of biotesting procedures based on the reactions of living organisms, using plant test-objects. The availability of a wide range of plants allows their use for testing various factors, including the analysis of the stimulating effect of substances on higher plants. The purpose of the study was to study the effect of the organic fertilizer «Grееnat» on the initial growth processes of higher plants in the laboratory by biotesting. The methodology of the study was to apply the biotesting method using higher plants widely used in agriculture, namely barley (Hordeum vulgare L.), soybeans (Glycine max L.), wheat (Triticum aestivum L.), maize (Zea mays L.), cucumber (Cucumis sativus L.), tomato (Solanum lycopersicum L.). Іt is established that the declared organic fertilizer «Greenat» contains: humic acids (67,68 g/dm3), fulvic acids (24,37 g/dm3) and organic substances (53,39%). The stimulating effect of the studied fertilizer on the initial processes of growth and formation of the root system of representatives of the group of cereals – barley (Hordeum vulgare L.) and wheat (Triticum aestivum L.) was revealed. Stimulating effect of organic fertilizer is also established for the initial growth processes of soybeans by estimating the length of shoots (increase by 38%) and for the initial growth processes of corn by estimating root length (increase by 22%). Root length of cucumber and tomato increased by 23 and 21% respectively, indicating the stimulating effect of the organic fertilizer «Greenаt» in the treatment of seeds of vegetable crops. The results of the research indicate the effectiveness of using the organic fertilizer «Grееnat» at the stage of seed treatment to stimulate the energy of germination and development of the root system of plants.

Abstract:
The article discusses various methods of pre-sowing seed stimulation. An increase in the activity of diastase in barley is noted - by 75% when the seeds are irradiated with ultrasound with a frequency of f = 48 kHz, an intensity of oscillations S = 42 W/cm² and an exposure time of t = 480 s. Ultrasonic action allows you to activate enzymes, which are of primary importance in the respiration of germinating seeds.

Abstract:
The effectiveness of the use of a tank mixture of siliplant micronutrient with insecticidal mordant Cruiser CS and siliplant micronutrient with growth regulators, micro- and organomineral fertilizers has been revealed. It was found that when seeds were treated with a tank mixture with an insecticidal protectant Kruiser,KS (0.5 l/t) with micro–fertilization Siliplant (60 ml/t), the germination energy of barley seeds increased by 2.2%, laboratory germination – by 4.0% and growth strength – by 4.0% compared with the protectant Kruiser, KS, and when plants were treated in phase 3 with a siliplant with epin extra, the greatest increase in the yield of barley grain of the variety was obtained Mikhailovsky - 0.35-0.41 t/ha. The use of siliplant with cytovit micro-fertilization, where the yield increase was 0.31-0.37 t/ha, siliplant with zircon - yield increase -0.33-0.36 t/ha and siliplant with organomineral fertilizer ecofus, where the yield increase was 0.24-0.34 t/ha, proved to be effective.
