猫儿山常绿和落叶阔叶树抗性生理生化指标的比较
Comparison of Physiology and Biochemical Index of Some Evergreen and Deciduous Broad-leaved Species in Mao'er Mountain,Guangxi,China
摘要
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 indicate the 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. The preliminary study suggests that the deciduous broad-leaved species have higher adversity-resistant than the evergreen broad-leaved species;while the deciduous broad-leaved species have lower activity of POD,which was possibly related to the leaves' harder lignification of evergreen broad-leaved species. The content of MDA may be related to the light intensity.关键词
