丛枝菌根真菌对镉胁迫下狗尾草生长及镉富集的影响
Effects of Arbuscular Mycorrhizal Fungi on Growth and Cadmium Enrichment of Setaria viridis Under Cadmium Stress
摘要
Abstract
In order to study the effects of arbuscular mycorrhizal(AM)fungi on plant growth under heavy metal stress,the effects of AM fungus Funneliformis mosseae on the growth,photosynthetic characteristics,Cd absorption and enrichment of Setaria viridis at different levels(0,10,30,50 mg·kg-1)of Cd were studied.The results showed that under the same level of Cd stress,AM fungi significantly increased the plant height,chlorophyll content,net photosynthetic rate,transpiration rate,stomatal conductance,apparent quantum efficiency and biomass of S.viridis.When the level of Cd was 50 mg·kg-1,the plant height,chlorophyll content,net photosynthetic rate,transpiration rate,stomatal conductance,apparent quantum efficiency and biomass of S.viridis inoculated with AM were significantiy increased by 51%,24%,33%,33%,26%,45%and 51%,respectively,compared with those treated without AM(P<0.05).Under the same level of Cd stress,AM fungi significantly increased Cd contents in roots,aboveground enrichment,root enrichment and Cd enrichment coefficient of S.viridis.The level of Cd was 50 mg·kg-1,compared with the control without inoculation,the Cd contents in roots,aboveground enrichment and root enrichment of S.viridis inoculated with AM increased by 39%,18%and 100%,respectively,which significantly promoted the absorption and enrichment of Cd by S.viridis.Above results could provide reference for the combined repair of Cd contaminated soil by AM fungi and S.viridis.关键词
