Abstract

The work is devoted to identifying the features of plant growth and development under laboratory conditions after presowing stimulation of seeds of pine (Pinus sylvestris L.), thuja (Thuja occidentalis L.) and eggplant (Solanum melongena L., variety "Universal") by UVB radiation of XeCl-excilamp. In all cases, conditions were identified in which UVB stimulation accelerates the germination of these seeds and the formation of seedlings. Additionally, microcoping of germinating 10-day-old thuja seeds performed on sections shows that the seeds show clear differences compared to the untreated control. If in the control, the seeds were just beginning to germinate (the appearance of the germ root), then in the experimental samples, on average, 5% of the seeds passed to the stage of development and formation of the seedling, had a developed root, hypocotyl, colored cotyledons, which began to shed the seed rind. The obtained primary data confirm the prospects of using narrow-band UVB radiation of XeCl-excilamps for pre-sowing stimulation of plant seeds.
