Analysis of laboratory germination and germination energy of Gypsophila thyraica Krasnova s. str. - a rare, relict, Podil endemic species. The seeds were irradiated with small doses (5, 15, 30 Gy) of gamma radiation (60Co) and germinated in laboratory conditions for 14 days in two repetitions. It was established that the seeds of G. thyraica irradiated with γ-rays prevailed in terms of the rate of germination and further growth and the number of seedlings. A stimulatory effect on germination, seed germination energy and seedling development was established with γ-irradiation at doses of 15 and 30 Gy. The energy of germination in all irradiated samples is low, in the control non-irradiated version it was not determined due to the absence of germinated seeds. The analysis of morphometric indicators also showed positive dynamics: in irradiated samples, the total size of seedlings increased (by 5-6 times compared to the control sample), depressed individuals were practically absent, while in control samples growth slowed down, seeds often did not develop, even after the start of germination. In general, the results of samples 1 and 2 are similar and confirm the conclusion about the stimulating effect of low doses of γ-irradiation on seeds.

The article reveals the current problems of the influence of γ-radiation and ultraviolet radiation on plants. An overview of the most important scientific results of modern research and prospects for their use in various spheres of human life. It is shown that depending on the dose of absorbed radiation in plants, different radiobiological effects are manifested. The study of the adaptive capacity of plants to different stressors is relevant for predicting the sustainability of ecosystems with increasing anthropogenic load in general and radiation in particular
