Plant and Soil Science

High-quality sowing material is an important condition for obtaining high yields and quality agricultural products. Since the seeds are storing for a long time, it is necessary to ensure an effective system of it protection against adverse factors during the period of achene formation, harvesting and storage in order to preserve its longevity, yields and yield properties. In case of incorrect storage, the seeds rapidly lose their qualities. Seeds of oil crops have a certain specificity of storage, because reserve constituents, which used by the bud for germination are deposits in the seed in form of fats. The purpose of study was to determine longevity of seeds linseed varieties under various temperature regimes of storage. In order to determine linseed germination, stored at different temperature regimes during 2016-2017, was conducted research at the educational research laboratory "Analytical research in Plant Growing" of the National University of Life and Environmental Sciences of Ukraine. Six domestic varieties of linseed were chosen - Iceberg, Vodograi, Blakytno-Pomaranchevyi, Evryka, Pivdenna Nich, Original and a variety of German selection - Liryna. Has been established that for storage seeds of linseed at stable low positive (+ 5⁰С) or negative temperatures, seeds longevity is maintained for a long period. Storage in unregulated conditions of variable temperatures leads to the fact that economic longevity of the seeds lost in a very short period.
