摘　　要：以"新津研4号"黄瓜为试材,研究了黄瓜在感染白粉病菌初期黄瓜叶片生理指标的变化情况。结果表明:在黄瓜感染白粉病菌初期,黄瓜叶片的呼吸强度呈现增强趋势,而光合速率受到抑制,呈现出减弱的趋势,叶绿素含量与光合作用有一定的相关性,所以也呈现出明显的降低趋势,可溶性糖可能因为其含量与诸多因素都相关,变化较为复杂,不能确切地描述其变化趋势,可溶性蛋白的含量明显呈增加趋势。Taking ＇Xinjinyan No. 4＇ cucumber as material,the physiological indexes changes of cucumber after infected by Sphaerotheca fuliginea at the beginning period was studied. The results showed that after being infected by Sphaerotheca fuliginea, cucumber leaf breathing intensity presented increase trends, and photosynthetic rate was restrained,presented a weakening trend. Chlorophyll content and photosynthetic had a certain correlation,so it was also showing significantly reduced trend. The sugar with many factors were related,its changes was relatively complex, so it was not exactly describe the change trend. The soluble protein content was obviously increasing trend.
