Effects of Ultraviolet-B Radiation on the Photosynthetic Pigments and Protein Content of Strawberry

The effects of ultraviolet-B (UV-B) radiations were studied on strawberry. The transplanted plants were irradiated with UV-B (280-320 nm) for 30, 60, 90 and 120 minutes on 20th, 40th, and 60th days after transferring. The enhanced UV-B radiation caused a negative effect on photosynthetic pigments and protein content of strawberry. Distinct decreased as a result of UV-B irradiation in contents of chlorophyll a, chlorophyll b, carotenoids and protein content was observed in strawberry. The impact of increase of duration of UV-B irradiation was also observed and found to be directly proportional.
