Abstract

Abstract: Ozone depletion in stratosphere has led to the increase of solar UV-B radiation reaching to the earth surface,which would affect crops to various extents.This review dealt with the effects of enhanced UV-B radiation on the physiological metabolism,DNA damage and protein content of crops.Enhanced UV-B radiation could increase crops’ flavonoid content but decrease their chlorophyll content and photosynthesis,induce gene change,and result in DNA damage and change of protein content.

Key words: potassium level, absorption., ¹³C, ¹⁵N, apple
