The growth and development of the fruits was investigated in two generations of eggplant, the seeds of which before the first sowing were exposed with γ- irradiation at different doses. Based on changes in the content of malondialdehyde (MDA), proline and activity of antioxidant enzymes was estimated the functioning of the antioxidant defense system in each generation of the plant. It is shown that the biometric parameters of fruits of the second generation are different from the fruit as the first generation and the control. Second generation typically characterized by intense development and high biomass accumulation. It was found that with increasing radiation dose increases the content of MDA, which is the main product of lipid oxidation by free oxygen radicals. It is assumed that with increasing doses is increased formation of reactive oxygen species in both generations of eggplant, which is accompanied by the large destruction in lipid membranes. It has been found dose-dependent changes of the proline content and activity of ascorbate peroxidase (APX), catalase (CAT), and superoxide dismutase (SOD). As is known, these antioxidants are actively involved in the protection of plants from the effects of radiation. It was determined that these changes are different also for the different generations. It has been established that the functioning of the antioxidant system in low doses leads to increased synthesis of proline and APX activation for the first generation of the plant. However the effect of stimulating the synthesis of proline and increasing the activity of the APX in the second generation does not occur. In contrast, at high doses, which induce large destructive action in lipid membranes, proline and APX play an insignificant role. At these doses, in both generations in the protection of plants against radiation are actively involved of SOD and CAT.
