中文摘要 |
采用叶片实验法研究了模拟紫外辐射(UV-BC)胁迫对47种植物叶片伤斑面积、叶绿素含量的影响.实验结果表明,叶片伤害面积和叶绿素含量的变化与紫外辐射剂量[辐射强度(Tn)×辐射时间(d)]成正相关关系.实验确定了47种植物的紫外辐射伤害阈值,并根据叶片伤害值对植物抗紫外辐射能力进行了排序. |
英文摘要 |
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. |
