番茄白粉病对番茄叶片光合特性的影响
Effects of Tomato Powdery Mildew on Photosynthetc Characteristics of Tomato Leaves
摘要
Abstract
[ Objective ] The paper was to explor the pathogenic mechanism of tormato powdery mildew, and to study the effects of the discase on photosynthetic characteristics of tomato [ Method] With tour tomato varieties as materials, the pathogen of tomato powdery mildew was artificially inoculated. After the varieties were infected. the paranmeters such as net photosynthetie rate. stomatal condnetance and transpiration rote of tomato leaf werr measured by Li - 6400 portable phutosynthesis detector ander natural lighting conditions. [ Result ] The nel photossynthetic rate. stumatal conductance and tralspiration rate of four tomato varieties all decreasei after infection however, the decrease extent of these parameters of four varieties was different. The parameters of Jinyangdajuxing ( No.4 ) and Xinsheng No. 1 ( No. 5 ) with heavy infeetion decreased greatly. while the parameters of improved 98 - 6 and Lujia ( No. 13 ) with lighl infeetion decreased lightly [ Conclusion ] the results could provide theoretical basis for Lhe study on pathogenie tnechanism. new prevention way and resistance breeding of tomato powdery mildew.关键词
