Abstract:
In nature, plants are continuously exposed to solar light. They cannot avoid exposure to UV-B radiation. The purpose of this investigation was to examine how UV-B radiation affects seed germination, seedling growth, protein and sugar contents and activities of antioxidant enzymes in pea (Pisum sativum) seedlings. Salicylic acid mediated physiological responses in UV-B stressed pea seedlings. UV-B exposure adversely affected germination and physiology of Pisum sativum L. Salicylic acid mitigated the impacts of UV-B stress. Seed germination decreased with increased duration of UV-B exposure. Enhanced activities of antioxidant enzymes in response to UV-B radiation played a protective role against UV-B radiation.
