摘要
随着人类商业运输和旅游活动扩大了病虫害的分布范围,气候变化增加了病虫害的爆发频率,造成了巨大的经济损失.光合作用是陆地生态系统吸收大气CO2的重要途径,也影响人类粮食生产.病虫害对植物光合作用的影响主要在两个方面:一方面通过采食植物的光和器官,减少了植物的光合能力.另一方面,病虫害侵染后植物的生理参数发生变化(如影响植物体中的叶绿素含量以及叶绿素a与b的比值、气孔导度和细胞内的CO2浓度),进而影响到植物的光合作用.因此,本文综述了近年来国内外关于病虫害对植物光合生理和光合作用的研究,并在此基础上对未来的研究方向进行了探讨和展望.
Owing to climate change and human activities in commercial transportation and tourism,distribution of and outbreak frequency of pests and diseases was increased,which caused huge economic losses to our society.Effects of pests and diseases on plant photosynthesis is mainly in two aspects：on the one hand through the ingestion of the plant light and organs,educed the photosynthetic capacity of plants.On the other hand,pests and diseases by affecting the photosynthesis of plant physiological ffects of plant.Photosynthesis is a key way sinking CO2 in terrestrial ecosystems,likewisely,it is influencing grain production.Pests and diseases lead to tissue lesions/damaged of plant regultiong photosynthesis.Therefore,this paper reviews photosynthetic physiology and photosynthesis in plants under pests and diseases,and then explored the focus of future researches.
