INFLUENCE OF A CULTIVAR AND CONDITIONS OF VEGETATION ON SOWING FEATURES OF BARLEY DURING STORAGE
Abstract
The experiments revealed the effect of the year of spring barley cultivation upon preservation of laboratory germination during storage. The seeds of spring barley varieties ‘Novichok’, ‘Lel’, ‘Tandem’ cultivated under contrasting vegetation conditions in Kirov region in 2007-08 have been laid for storage after the first year yield. The studies showed specificity of the barley cultivar according to the ability to preserve seed germination during long storage. The cultivar ‘Lel’ is characterized by the largest potential of biological longevity, which kept seed germination during five years of storage. The varieties differed in the time of seed aging. During all period of storage, laboratory germination of the varieties ‘Lel’, ‘Novichok’ and ‘Tandem’ was reduced on 3,0%, 3,8% and 6,5% respectively. The analysis of weather conditions was carried out during the period of grain ripening. The results of double factor variance analysis showed a significant effect of the factors ‘variety’, ‘year’ and their interaction on safety of laboratory seed germination during long storage. There are some authentic distinctions in germination among the seeds, grown in the years with different growing conditions. The studies showed that barley cultivars have various potential of agronomic longevity. The seeds of variety ‘Tandem’ kept their sowing properties during three years, the seeds of varieties ‘Lel’ and ‘Novichok’ kept their sowing properties during four-five years. It’s necessary to take into account the peculiarities of the cultivars and conditions of plant germination in the year of yield if the seeds are laid for a long storage.
