Abstract

APPLICATION OF THE METHOD OF ACCELERATED AGING OF DURUM WHEAT SEEDS (TRITICUM DURUM DESF.) TO ASSESS THEIR LONG-TERM STORAGE CAPACITY The article is devoted to the analysis of the effectiveness of accelerated aging (AA) method to assess the shelf life of durum wheat seeds. The use of AA aging method, which consists in incubating seeds for 72 hours at high humidity (90- 100%) and air temperature (430C), allows you to adequately simulate the impact of adverse factors that play a decisive role in the aging of durum wheat seeds. Cluster statistical analysis of such important morphophysiological parameters as seed germination, average seedling root length, crude and dry root biomass and electrolyte leakage predicting terms of specimen long-term storage in the plant genetic bank. Keywords: durum wheat, accelerated aging, germination, seed germination energy, seed storage potential.
