在不同生境光强,即100%自然全光照(Natural sunlight,NS)、80%NS、25%NS、5%NS的人工遮阴条件下,研究了生境光强对云南金钱槭(Dipteronia ayeria Henry)幼苗生长及光合速率的影响.结果表明,光照是影响幼苗生长的重要环境因子.株高、基径、生物量和光速速率均以5%NS处理的最小,基径、生物量和光合速率随着遮阴程度的增加而减小.80%NS的处理对云南金钱槭幼苗的生长最有利,幼苗的株高、基径、生物量和光合速率均在80%NS处理下获得了最大增长,说明适当遮阴(80%NS)有利于云南金钱槭幼苗的生长.
在不同生境光彊,即100%自然全光照(Natural sunlight,NS)、80%NS、25%NS、5%NS的人工遮陰條件下,研究瞭生境光彊對雲南金錢槭(Dipteronia ayeria Henry)幼苗生長及光閤速率的影響.結果錶明,光照是影響幼苗生長的重要環境因子.株高、基徑、生物量和光速速率均以5%NS處理的最小,基徑、生物量和光閤速率隨著遮陰程度的增加而減小.80%NS的處理對雲南金錢槭幼苗的生長最有利,幼苗的株高、基徑、生物量和光閤速率均在80%NS處理下穫得瞭最大增長,說明適噹遮陰(80%NS)有利于雲南金錢槭幼苗的生長.

Under different light intensities such as 100% natural sunlight (NS),80% NS,25% NS,5% NS in shade house,effects of light intensity on the photosynthesis rate and growth of Dipteronia dyeriana seedlings were studied.The preliminary results were as follows: Light was an important environmental factor for the growth of D. dyeriana seedlings.The plant height,branch diameter, total biomass and photosynthesis rate were the smallest under 5% NS. Light intensity was positively corre-lated to branch diameter, total biomass and photosynthesis rate of D. dyeriana seedlings. The treatmant of 80% NS was most suited for established seedlings in plant height, branch diameter, total biomass and photosynthesis rate. Appropriate shade of 80% NS was beneficial to D. dyeriana seedling growth.
