Effects of Ultraviolet(UV-BC) Radiation Stress on Blade Visible Injury of Forty-Seven Plants
紫外辐射(UV-BC)对47种植物叶片的表观伤害效应

The effect of simulated ultraviolet (UV-BC) radiation stress on the area of foliar injury and chlorophyll content of forty seven garden plants were examined with leaf. The result shows that change range of area of foliar injury and chlorophyll content was positively correlated with UV-BC radiation dose radiant intensity(Tn)×radiant time(d)]. The injury threshold values of forty seven plants were established. The UV-BC radiation resistance of plants was put in order by injury values of leaves.
