Витривалість насіння сортів гороху до чинників зберігання та заморожування

Abstract

Tolerance of seeds of 15 pea varieties of different use directions to the factors of ageing and to freezing at temperature –20^oC was studied. In model experiment of “quick aging”, relationship of tolerance with the variety peculiarities is found . Seeds of different pea varieties more significantly respond on the “quick aging” by changing of germinative energy and less – by changing germination. Seeds of pea varieties of vegetable use direction are less tolerant to storage, than of the varietiesof  grain and mowing groups. Among varieties of last two groups, more tolerant to “quick ageing” were ones having comparatively small seeds with 1000 grain mass from 164 to 215 g. Freezing of  seeds of a number pea varieties increases the characteristics of germinative energy and germination, decreases a quantity of seeds anomalous germinating and infected by pathogens
