Abstract
One of the factors of abiotic stress is ultraviolet radiation. Acting on the photosynthetic apparatus of the cell, radiation causes a change in the intensity of photosynthesis - the main physiological process that determines the growth, development and productivity of plants. Quantitative changes in the content of photosynthetic pigments and the intensity of growth processes are indirect indicators of plant resistance to the effects of various environmental factors. With the right treatment regimes, UV radiation can be used to improve the sowing quality of seeds and increase the productivity of grain crops. The article presents the results of studying the effects of small doses of UV-C radiation on laboratory germination, the content of chlorophylls a and b, carotenoids in soft spring wheat seedlings, as well as indicators of the amount of chlorophylls, the ratio of chlorophylls a / b, the ratio of the sum of chlorophylls and carotenoids. According to the results obtained, the effect of UV radiation in the studied time range (30-180 seconds) led to an increase in laboratory germination and an increase in the content of chlorophylls and carotenoids, no dependence on the change in pigment ratios on exposure time was revealed.
