dc.description.abstractThe problems of increasing plant productivity are among the leading at the present stage of human development. Most often, chemicals are used to achieve this goal, which leads to a deterioration in the environmental situation. An alternative is the use of physical means, in particular the use of laser systems to stimulate plants. One of the most promising areas is the use of LED lasers, which at the same radiation power have smaller dimensions and use much less energy than He-Ne or other lasers. The results of studies of the influence of seed irradiation Cucumis sativus L. are presented in the paper. cv Cornish Paris LED lasers emitted red (wavelength 635 nm) and blue (wavelength 405 nm) light. Irradiation was carried out according to the scheme of a complete factor experiment, which made it possible to detect the action of each of the light sources and their complex action. Determination of growth parameters was carried out using standard methods. The area of the leaves was determined after scanning them on a tablet scanner. The results showed a significant positive effect of irradiation of seeds on the growth processes of experimental plants. Irradiation with red light with an energy of 51.10 mJ/cm2 and complex irradiation improved oral parameters such as root length by 25.0-42.5%, shoot height by 19.4-77.4% compared to plants grown from non-irradiated seeds. In experimental plants, the leaf area increased significantly and by 22.4-41.5% the total leaf area grew. Studies have also revealed a significant positive effect of seed irradiation on the plant pigment complex. In plants grown from irradiated seeds, the content of chlorophyll A is 25.5-30.9%, and chlorophyll B is 754.0-105.5% higher than in control plants. The ratio of chlorophyll A to chlorophyll B under these conditions was not likely to change. Studies have shown the prospects of using laser irradiation using LED laser systems to improve the growth, development and productivity of agricultural plants.en_US
