INFLUENCE OF PRE-SOWING SEEDS TREATMENT OF PERENNIAL LEGUMES ON THEIR GERMINATION

Abstract

Many researchers have proved the high efficiency and, especially, the environmental friendliness of the pre-sowing treatment of seeds of agricultural crops, including seeds of perennial leguminous herbs. The search for new methods of seed treatment, such as UV-irradiation, the use of nano-preparations, is relevant. The article presents the results of a study on the effect of ultraviolet radiation and a silicon-containing preparation Nanokremnii on the germination of seeds of meadow clover Ranniy 2, variegated alfalfa Victoria and eastern galega Yalginskiy. It was revealed that pre-sowing treatment of grass seeds with Nanokremnii and UV-irradiation didn’t affect the increase in their laboratory germination. The amount of solid seeds of meadow clover in the variants UV-irradiation + Nanokrenmii and Nanokremnii + UV-irradiation decreased to 2-3%. The infection rate of eastern galega seeds decreased to 7.9–9.5% in almost all studied variants. The use of the Nanokremnii preparation and UV-irradiation on variegated alfalfa seeds contributed to the tendency to increase the sprout length to 2.4 cm, the root to 1.5 cm, the degree of seedlings development to 3.0 points, the growth force to 29.8%.
