Abstract
The study focuses on the effect Ultraviolet-B rays (UV-B) were studied how it affected on seed germination seedling growth, chlorophyll a and b contents, soluble phenols, anthocyanins, flavones contents, phenylal of pea (Pisum saivum). The seed germination percentage significantly suppressed by UV-irradiance. Both root and shoot growth of the seedlings were markedly reduced by enhanced UV-B radiation. UV-B irradiation substantially decreased both chlorophylls a and b and the total amount of chlorophyll a plus b compared to controls. However, chlorophyll a/b ratio was generally elevated. Remarkable accumulation of total soluble phenols occurred in response to UV-B radiation. The levels of anthocyanins and flavones in treatments over the controls as they provide a protective mechanism to UV-B radiations. In general, the growth and physiological responses to UV-B radiation were more pronounced at greater exposure period.
