摘要
Abstract
This study investigated the effects of drought severity on Camphor tree seedling growth u-sing seedlings from Yuechi County.Experimental treatments included normal water supply,moderate drought(50％-55％field water retention),severe drought(30％-35％field water retention),and AMF inoculation.Results demonstrated that drought stress significantly inhibited seedling height,rhizome develop-ment,total leaf area,and biomass accumulation,with the inhibitory effect increasing as drought intensity in-tensified.AMF inoculation effectively mitigated drought-induced stress,enhancing total biomass and photo-synthetic capacity.Under severe drought conditions,AMF inoculation increased total biomass by 32.6％and significantly restored photosynthetic capacity.The study elucidated the drought tolerance mechanisms of Camphor seedlings and the drought-promoting role of AMF,providing scientific evidence for improving cul-tivation survival rates in arid regions.关键词
