不同林分密度下叶片功能性状比较
Comparison of Leaf Functional Traits Under Different Stand Densities
摘要
Abstract
In 2020,10 to 12-year-old Ormosia hosiei and Cyclobalanopsis myrsinifolia trees in a mixed stand of rare tree species at the grass carp pond forest farm in Jingning,Zhejiang Province were studied,the morphological changes,specific leaf weight and physio-logical changes of leaves under different stand densities(800,1600,2500 and 3300 plant·hm-2)were analyzed.The results showed that under the density of less than 2500 plants·hm-2,the leaf characters of Ormosia hosiei had no significant change,but under the density of 3300 plant·hm-2,the leaf area,weight and thickness all decreased,the leaf traits of the C.myrsinifolia were a-dapted to the seasonal changes of the associated tree species,but were not significantly affected by stand density.There was no signif-icant difference in physiological and biochemical indexes between saplings of Ormosia hosiei and C.myrsinifolia under different den-sities,and it was suitable to grow under the stand density of 1600～2500 plant·hm-2.关键词
