Abstract

Analysis of spacing patterns in a monospecific stand of Croton menthodarus Benth. (Euphorbiaceae) suggests the presence of intraspecific competition. Analysis of the coefficient of variation for crown diameters suggests that increased plant density results in mortality of smallest individuals.

摘要

对巴豆属植物（大戟科）单一物种林分中植株间距模式的分析表明存在种内竞争。对树冠直径变异系数的分析表明，植株密度增加会导致最小个体死亡。
