摘　　要：在0.1、0.3和0.5 kV.cm-1不同场强的静电场长期作用下,大豆、黄瓜和油青菜心叶片的叶绿素含量、PSⅡ的潜在活性和原初光能转换效率、叶绿体Mg2+-ATP酶和Ca2+-ATP酶活性以及光合代谢产物可溶性蛋白和可溶性糖含量均有不同程度的提高,表明用静电场长期处理作物能够有效地改善作物的光合性能,促进作物的光合作用与光合产物的积累.不同作物对不同场强静电场的响应有所差异,本试验条件下,对大豆、黄瓜和油青菜心处理效果最好的静电场强度分别为0.1、0.3和0.5 kV.cm-1.Seedlings of Glycine max, Cucumis sativus and Brassica campestris were treated with 0. 1,0. 3 and 0. 5 kV · cm ^-1 electrostatic field for 10 d. The chlorophyll content,the potential activity and primary photochemical efficiency of PS II , the activities of Ca^2＋ - ATPase and Mg^2＋ - ATPase in chloroplast membrane as well as the contents of soluble protein and soluble sugar in leaves of three crops were obviously increased compared with the control. The result indicated that crops treated with electrostatic field could efficiently improve photosynthetic properties, leading to the promotion of photosynthesis and accumulation of photosynthate in crops. The responses of tested three crops to electrostatic field were somewhat different. Glycine max, Cucumis sativus and Brassica campestris had the most prominent effect while treated with 0. 1,0. 3 and 0. 5 kV ·cm^-1 strength electrostatic field, respectively.
