In the scientific activity of the new era, conducting scientific research on the protection and effective use of the natural resources and biodiversity of the country has been determined as the main goal. One of the main research directions of the Institute of Radiation Problems is the application of radiation technologies in cotton and grain growing.

The employees of the institute working in this field were on a business trip to Ganja under the leadership of the executive director of RPI, doctor of philosophy in physics and mathematics, associate professor Ravan Mehdiyeva, and discussed the results of this year's research work.

At the meeting held in a business environment, opinions were exchanged with the participation of experts on the results obtained, the signs of radioactive radiation in the second generation were investigated, and future research was determined.

At the joint session of the Scientific Council chaired by Ibrahim Jafarov, the director of the Scientific Research Institute of Plant Protection and Technical Plants of the Ministry of Agriculture of the Republic of Azerbaijan, the corresponding member of ANAS, the executive director of IRP R. Mehdiyeva, gave information about the research conducted at the institute. She said that agriculture is one of the priority directions in the development of the non-oil sector in the Republic of Azerbaijan. Therefore, in the last two years, at the Institute of Radiation Problems, scientific research has been carried out in the direction of increasing the productivity of plants by applying radiation technologies, as well as obtaining varieties of seeds resistant to diseases, drought and salinity, as well as the positive effect of ionizing radiation on the sterilization of seeds, cleaning them from harmful microbes, as well as their development, application possibilities are being investigated, as well as relevant proposals have been prepared in this field. Thus, in 2020-2022, the research works on cotton in the institute are carried out on the basis of the Agreement signed by the Institute of Radiation Problems of ANAS with the Scientific Research Institute of Plant Protection and Technical Plants, and the research works on wheat are carried out within the framework of scientific cooperation agreements with the Scientific Research Institute of Agriculture of the mentioned ministry.

Within the framework of cooperation, scientific-research works on the “Application of radiation technologies in the purchase of wheat and cotton varieties that are productive and resistant to extreme environmental factors “are successfully carried out in the institute.

Ganja-160, Ganja-182 and Ganja-183 cotton varieties were selected as research objects.

Cotton seeds were treated with different doses of gamma rays with the help of Co-60 isotope in the RUXUND-20000 device at the Scientific-experimental complex of “Isotope Origin Ray Sources” of the Institute of Radiation Problems of ANAS. For this purpose, 5, 10, 50, 100, 200, 300, 400 Gy radiation doses were selected for cotton seeds.

Irradiated cotton seeds were grown together with control seeds both in laboratory conditions(in vegetable pots), in the experimental field of the laboratory, and in the experimental field of the Technical Plant Selection Department of the Scientific Research Institute of Plant Protection and Technical Plants(Ganja city). During the cultivation of cotton, researches were carried out by employees of both institutes, and the collected cotton was analyzed in a modern laboratory purchased on the basis of the technical assistance grant project of the International Atomic Energy Agency. The dependence of malondialdehyde(MDA), proline, total protein content, as well as the activity of catalase and APO on the radiation dose was studied in order to conduct biochemical analyzes of cultivated cotton, to study the molecular mechanism of the response of seeds to the effect of radioactive radiation, and the activity of the antioxidant defense system under radiation stress and it was determined that the treatment of cotton seeds with certain doses of gamma rays before sowing has a positive effect on their percentage of germination in the field and the quality indicators of cotton fibers. As a result of this effect, the shape of the cones and the number of cones in the bar organs can also change.

Speaking later, the head of the IRP” Radiobiology” Laboratory, Professor Elimkhan Jafarov, brought to the attention of the members of the Scientific Council the biological characteristics of the 2nd generation of cotton seeds irradiated with ionizing rays and the results obtained in 2022. E.Jafarov said that treatment of seeds with γ-rays in doses of 5-400 Gy before sowing allowed to obtain forms with higher yield, high fiber yield, long-staple and high mass of cotton per boll at (5-10)Gy doses.

Then Intizar Zeynalova, PhD student of the Scientific Research Institute of Plant Protection and Technical Plants, gave a report on her researches.

The Scientific Council also heard the report of the head of the laboratory of biophysics of plant signaling systems of the National Academy of Sciences of Ukraine, the Institute of Cell Biology and Genetic Engineering, with which RPI conducts joint research, Professor Namig Rashidov, about the research he has conducted in the Chernobyl experimental zone for many years.

The Scientific Council also heard the report of Professor Namig Rashidov, the head of the “Biophysics Laboratory of Plant Signaling Systems” of the National Academy of Sciences of Ukraine, the Institute of Cell Biology and Genetic Engineering, with which IRP conducts joint research, about the research he has conducted in the Chernobyl experimental zone for many years.

Summarizing the results of the conducted research, Ibrahim Jafarov talked about the scientific basis of the feasibility of continuing the research in the next year.
