摘　　要：作物对太阳紫外线辐射增加的生物效应及其评估郑有飞，杨志敏，颜景义，万长建（南京气象学院，南京２１００４４）Ｂｉｏｌｏｇｉｃａｌｒｅｓｐｏｎｓｅｏｆｃｒｏｐｓｏｎｅｎｈａｎｃｅｄｓｏｌａｒｕｌｔｒａｖｉｏｌｅｔｒａｄｉａｔｉｏｎａｎｄｉｔｓｅｓｔｉｍａ...Studies on the effects of enhanced solar UV radiation on the growth and physiology of soybean and wheat show that under natural conditions,the increase of UV radiation can inhibit the net photosyntetic rate and the growth of leaves,stems and roots of both tested crops.The decrease of biomass and yield is caused by the decline of transpiration and stomatal conductance of leaves.Estination of the crop response on the enhanced UV radiation shows that the mean error between fitting value and observed one is 0.30￣8.56%.
