The article presents the results of a study of the effect of the CO-4 stabilizer on the processes of degradation of high-density polyethylene when it is exposed to ultraviolet (UV) radiation by infrared (IR) spectroscopy. It has been shown that the absence of a stabilizer in the polymer leads to a decrease in the amount of vinyl groups. It is assumed that vinyl groups in samples without a stabilizer interact with alkyl radicals, which are formed during UV irradiation.

Optical radiation is one of the types of pre-sowing treatment of seeds, it allows in the early stages to start the successful growth of the future plant, by activating the physical and biochemical processes occurring in the seed. The article presents the results of studies of the effect of the dose of ultraviolet radiation on the productive qualities of barley seeds of the «Academician» variety. Research in this direction is relevant since pre-sowing treatment of seeds significantly improves the quality of the crop.
