Abstract
The effect of Reduction of ultraviolet-B irradiance on the content of flavonoid in the leaves of wheat (Triticum aestivum Linn.) was investigated. The results showed that the flavonoid content in leaves of wheat decreased significantly by reducing the radiation intensity of ultraviolet-B near the earth's surface. The most sensitive phrases were from jointing to spike formation stage. The flavonoid content in upper leaves was higher than that in the middle and lower leaves. The flavonoid content of the bottom leaves was higher significantly than that of the top and middle leaves. The chlorophyll content in leaves of wheat increased significantly, as the radiation intensity of UV B near the earth's surface was reduced.
