    摘要:

    研究了遮阴条件下3a栲树幼苗(Castanopsisfargesi)枝、叶构件动态和生物量变化,结果表明:幼苗枝、叶构件逐月变化,在春、夏季生长迅速,秋、冬季生长缓慢,而叶调落量在春、秋季各有一次高峰,这可能与光照强度有关;现存叶数、枝构件数目和总生物量均高于对照,可见,适当遮阴有利于栲树幼苗的生长;但遮阴对枝构件大小级分布趋势影响不大,均为“金字塔”型,这表明幼苗正处于旺盛生长阶段。

    Abstract:

    Three year old Castanopsis fargesii seedlings were studied under shading for the demography and biomass of their leaves and branches.It was found that the growth of leaf and branch modules,in general,changed monthly,grow
