Influence of low temperature and fluorescent light on the cereal seeds during the germination tests

Abstract

Testing the capacity of the cereal seeds to produce plants in the fields, by germinating under the best laboratory conditions, had as goal to assess their quality for sowing, commercialization or long-time conservation. The experimental biologic material was represented by twelve oat genotypes, eighteen barley genotypes and twenty rye genotypes from the seed collection, stored in the Suceava Genebank. The germination tests were carried out in laboratory, on the artificial substrate made of filter paper, by the BP (between paper) method, under two experiencing conditions. The scientific grounding of results was done through the correlation between the germination capacity of the cereal seeds at dark and the germination capacity under fluorescent light and low temperature, before incubation. The differences found in the germination percents of each species pointed out the role of fluorescent light and low temperature, a significant correlation between viability seed and the two factors in barley being found, as compared to the other tested species. In the routine tests from seed control laboratories, they may successfully use the low temperature treatment in barley, before incubation, and the exposure at fluorescent light, during incubation, even if this species is no longer found at germination repose. Percent increases in the germinating capacity were registered.
