干旱胁迫下丛枝菌根真菌对草莓根系生长的影响
Effects of Inoculating Arbuscular Mycorrhizal Fungi on Root Growth of Strawberry under Drought Stress
摘要
Abstract
[Objective]To study the effectes of inoculating arbuscular mycorrhizal fungi (AMF) on root growth of strawberry under drought stress.[Method]Strawberry cultivar "Sweet Charlie" was selected as test cultivar,and Glomus mosseae was the tested arbuscular mycorrhizal fungi,the non-inoculated strawberryy was taken as the control.The root growth changes of strawberry were measured under three different levels of water (normal irrigation,mild drought stress,moderate drought stress).[Result]AMF colonization rate decreased rapidly with the increase of drought stress,while AMF dependency increased with the rise of drought stress.Under the drought stress,AMF inoculation changed the root morphology of strawberry and increased root fresh and dry weight of strawberry.The root antioxidant enzymes activities of strawberry were also improved significantly.Thus the damages of drought stress on the root of strawberry were alleviated.[Conclusion]AMF inoculation improved the drought resistance of strawberry.The results provided the theoretical basis for AMF's application in strawberry drought resistance research.关键词
