Abstract
UV-B was used to radiate fluecured tobacco K326. Then the effects of different modes and intensities of UV-B radiant on tobacco growth,photosynthetic physiology,pigment,polyphenols,sugar and nicotine contents studied. Results show that tobacco K326 stem dwarfs and thickens. Also leaf area and net photosynthetic rate moderately decline when flue-cured tobacco K326 is treated with UV-B radiation. Chlorophyll,sugar and nicotine contents decrease with increasing of UV-B radiant intensity. Chloro-phyll content is enhanced by low UV-B radiant intensity. The content of polyphenol in relation to plant stress resistance increases significantly,positively correlated with treatment time and radiant intensity. Pretreatment of rational intensity of UV-B radiant can increase chlorophyll,total carotenoids,and total sugar contents.
