Abstract: The studies was conducted in beginning of May,2010.The activity of antioxidant enzymes and some variations in physiological indexes were studied.The studies were about two evergreen broad-leaved species and two deciduous broad-leaved species in Mao'er Mountain,Guangxi.The results showed that there are some physiological differences between two evergreen broad-leaved species and two deciduous broad-leaved species.These differences could indicatethe different physiological mechamism of evergreen broad-leaved species and deciduous broad-leaved species resistant.The result showed that the deciduous broad-leaved species have higher activity of SOD,CAT and more content of Pro and soluble sugar at the same stage compared with evergreen broad-leaved species.Thepreliminary study suggests that the deciduous broad-leaved species have higheradversity-resistant than the evergreen broad-leaved species;while the deciduous broad-leaved species have lower activity of POD,which was possibly related tothe leaves' harder lignification of evergreen broad-leaved species.The content of MDA may be related to the light intensity.

Key words: Mao&apos, er Mountain,Guangxi, evergreen broadleaved species, deciduous broadleaved species, antioxidant protection system, resistant
