摘　　要：为促进西瓜病害的防控,以西瓜幼苗为试验材料,研究了不同浓度可杀得叁千叶面喷施对西瓜幼苗活性氧含量、保护性物质活性及含量、MDA含量和电解质渗透率的影响。结果表明:随着氢氧化铜处理浓度的提高,西瓜幼苗叶片内超氧阴离子(O2·)的产生速率和H2O2的含量上升;CAT活性、游离脯氨酸含量先升高后降低,SOD活性、POD活性升高;MDA含量和电解质渗透率升高。In order to promote the prevention and control of watermelon diseases,in this study watermelon seedlings were used as test materials,the effects of spraying different concentrations of Kocide 3000 on physiological indexes of watermelon seedlings were studied.The results showed that the content of O■·,H2O2,SOD,POD,MDA and electrolyte permeability in watermelon seedling leaves increased with the increase of copper concentration.Proline and CAT in watermelon leaves increased first and then decreased with the increase of copper concentration.
