两种丛枝菌根真菌和黄瓜花叶病毒复合作用对烟草生长和光合特性的影响
Interactive effects of two arbuscular mycorrhizal fungi and Cucumber mosaic virus on the growth and photosynthetic capabilities of tobacco
摘要
Abstract
In order to elucidate the interactive effects of arbuscular mycorrhizal fungi(AMF)and Cucumber mosaic virus(CMV)on the growth and photosynthetic capabilities of tobacco,a greenhouse experiment was conducted.During the experiment,inoculated(inoculation with Funneliformis mosseae,Diversispora versiformis,either alone or their combination)and non-inoculated(inoculation with sterilized AM fungi)tobacco seedlings were randomly subjected to two CMV regimes(inoculated with or without CMV).The results showed that CMV significantly decreased the total dry weight,net photosynthetic rate(Pn)and instantaneous water use efficiency(WUE),whereas Mycorrhizal inoculation significantly improved root colonization rate,fungal activities of succinate dehydrogenase and alkaline phosphatase,total dry weight,Pn and WUE of tobacco plants.Furthermore,whether inoculation with CMV or not,mycorrhizal inoculation conferred positive effects on the growth of tobacco plants especially with the inoculation of D.versiformis,and there were differences in mycorrhizal benefits between AM fungi species.In conclusion,mycorrhizal inoculation promoted the resistance of tobacco to CMV,and the enhancement in photosynthetic capabilities might be the underlying mechanism for mycorrhizal efficiency.关键词
