| 摘 要： | 使用CI-310便携式光合作用测定系统研究了美洲斑潜蝇幼虫为害对几种作物光合作用的影响。结果表明，随着叶面积受害级别的增高，蓖麻和菜豆的光合速率（Pn）、气孔导度（Gs）、蒸腾速率（Tr）和气孔限制值（Ls）总体呈下降趋势，不同受害级别与胞间CO2浓度（Ci）的变化呈正相关。美洲斑潜蝇幼虫潜食蓖麻和黄瓜叶片中的栅栏组织后，叶片中叶绿素a、b和叶绿素总量都较对照减少，并且随着潜食级别的增高，减少量逐渐增大。叶面积受害级别与叶片的叶绿素总量之间呈高度负相关，其相关系数分别为r =-0.93（蓖麻）和r=-0.95（黄瓜）。菜豆、黄瓜和丝瓜的叶肉被害后，不同受害级别叶片的鲜重变化无规律性。

| Abstract: | CI-310 portable photosynthesis system was used to measure effects of leaf mining by Liriomyza sativae larvae on photosynthesis of some crops. The results showed that with the increase in the mined area grade of leaf by miners, the photosynthetic rate (Pn), stomatal conductance (Gs), transpiration rate (Tr) and stomatal limiting value (Ls) in castorbean Ricinus communis and kidney bean Phaseolus vulgaris generally decreased. Positive relations existed in the above two crops between different treatment grades and intercellular CO-2 concentration (Ci) variation. After the palisade tissue of castorbean and cucumber Cucumis sativus leaves were mined by L. sativae larvae, their chlorophyll a, b and total chlorophyll contents were decreased compared with that of the control; and the higher the mined grade, the greater the decrement. There were negative relations between the mined grade of leaf and total chlorophyll contents, their coefficient of correlation was -0.93 for castorbean and -0.95 for cucumber. After the mesophyll of kidney bean, cucumber and suakwa vegetable sponge Luffa cylindrica were mined, the leaf fresh weights of different grades showed no regularity in variation. |
