[Effects of calcium and ABA on photosynthesis and related enzymes activities in cucumber seedlings under drought stress]

To investigate the effect of calcium and ABA on photosynthesis and the activities of antioxidant enzymes in cucumber seedlings under drought stress, the cucumber was used as the expe-riment materials, normal nutrient solution culture was considered as the control, and PEG-6000 application in the nutrient solution simulated the drought stress. There were five different treatments which were spraying water, ABA, CaCl为探讨在干旱胁迫下钙与脱落酸对黄瓜幼苗光合作用及相关酶活性的影响,以黄瓜为试材,正常营养液栽培为对照,利用PEG-6000(聚乙二醇)营养液添加模拟干旱胁迫,设干旱胁迫条件下幼苗叶片喷施清水、脱落酸(ABA)、CaCl
