中文摘要：
以菜豆为实验材料,用紫外辐射处理,测定植物各叶位叶片的生理活性。结果表明,紫外辐射条件下,叶片的光合、蒸腾速率先升高,随后迅速降低,辐射处理3 h对光合作用的抑制程度随叶位升高而增加;第1叶气孔导度和胞间CO2浓度随辐射处理略有增加,而第2、3叶的则先升高随后降低;辐射处理使叶绿素含量先降低随后有所增加,但明显增加叶片丙二醛(MDA)含量;紫外辐射处理后,叶片过氧化物酶(POD)活性先升高随后降低,紫外辐射3 h第1叶POD活性比对照降低26.9%,辐射使第1叶超氧化物歧化酶(SOD)活性略有升高,但明显降低第2、3叶的SOD活性。
英文摘要：
The study on the physiological activities of bean leaves at different position on stem showed that,under ultraviolet radiation,the photosynthesis and transpiration rate of leaves increased first and decreased then.After 3 h ultraviolet radiation,the inhibition rate of photosynthesis was increased with increasing leaf position.The stomatal conductance and intercellular CO_2 of the first leaf enhanced slightly,while those of the second and third leaves enhanced first but decreased then.Ultraviolet radiation m...
