摘  要:
在大棚栽培条件下,研究了白粉虱侵害对黄瓜叶片气体交换参数、叶绿素荧光参数、抗氧化酶活性、丙二醛和脯氨酸含量的影响。结果表明:白粉虱侵害使黄瓜净光合速率、Fv/Fm明显降低,并且侵害程度越重,降低越明显;叶片中叶绿素含量、类胡萝卜素含量也随着侵害的加重而降低越明显;白粉虱侵害明显增加了叶片抗氧化酶活性和丙二醛、脯氨酸含量,并且侵害越重,增加越明显。说明白粉虱侵害时,黄瓜受到了明显的胁迫,胁迫植株通过提高抗氧化酶活性及增加丙二醛和脯氨酸含量等来适应外界胁迫。

摘  要:
Effects of Trialeurodes vaporariorum invasion on gas exchange parameters,chlorophyll fluorescence parameters,antioxidant enzyme activity,MDA and proline content in cucumber leaves were studied under greenhouse cultivation conditions.The results showed that the net photosynthesis rate and Fv/Fm of cucumber decreased significantly with Trialeurodes vaporariorum invasion,and the more serious damage,the more obvious the reduction.The content of chlorophyll and carotenoid in leaves decreased with the increase of damage.The cucumber was under stress when Trialeurodes vaporariorum infringed,and the plants adapted to the external stress by improving the activity of antioxidant enzymes and increasing the content of MDA and proline.'
