Özet: In this study, UV protection of the same type of pigments obtained from different types of bacteria on wheat (Triticum aestivum cv Kirik) plant was investigated. The seedlings were grown in pots under optimal conditions for a total of 15 days. Pigments obtained from bacteria were applied on the 12th day, and after 24 hours, all UV was applied except for the control group. The plants harvested after the fifteenth day were used as experimental material. As a result of the application, the amounts of hydrogen peroxide (H2O2) and malondialdehyde (MDA) increased in the seedlings that were only UV applied. In the pigment applications we use as a preservative, it has been determined by the measurements that it reduces the UV damage. In addition, antioxidant enzyme activities; Superoxide dismutase (SOD), catalase (CAT) and peroxidase (POX) were examined and it was observed that these enzymes increased in pigment applications and showed protection against UV.
