摘要
测定了竹林下、水杉林内及林缘、空地已栽植3 a的薄片变豆菜生长及光合日变化。结果表明:竹林、水杉林东、空地植株叶面积指数较大,净光合速率较高,生长良好;水杉林内叶面积指数较小,净光合速率较低,生长一般;水杉林西叶面积指数最小,净光合速率较高,生长受到抑制。
Growth and diurnal photosynthetic change of three years old Sanicula lamelligera under different light condition were studied.The results showed that leaf area index and Pn of plants under bamboo forest,the east of metasequoia glyptostroboides forest and the space were higher and growth better than under metasequoia glyptostroboides forest;the plants in the west of metasequoia glyptostroboides forest had miniest leaf area index,lower Pn and growth bad.
