Effects of X-Ray irradiation on germination and phytosanitary condition of cereal and oilseed crops

Abstract

The laboratory study explores the impact of X-ray radiation on the germination of flax, rapeseeds and wheat seeds naturally infected with fungi, as well as on their phytosanitary condition after irradiation applying different doses. During the research, it was found that pre-planting treatment of naturally infected wheat, rapeseeds, and flax seeds with X-rays with the doses ranging from 4 Gy to 150 Gy had both stimulating and inhibitory effects on the growth rate of seeds and their phytosanitary status. To ensure a superior quality of the new crop, pre-planting irradiation doses were established, on the one hand, to maximize the seed germination rate of seeds, and on the other hand, to completely inhibit the activity of phytopathogen in seeds. It was established that X-ray radiation with the doses of 30-50 Gy, 16 Gy, 16 Gy and 12 Gy is the most efficient method for pre-planting treatment of Novosibirskaya 29 wheat seeds harvested in 2021 and in 2022, Builder rapeseeds and Severny flax seeds, respectively.
