摘  要：
为了探究白桦(Betula platyphylla)种群当年构件的特性,了解其生存策略及对环境的响应。文章研究通过测定各构件的数量、生物量及构件间关系,对不同光照条件和不同径级的构件进行分析。结果表明:不同光照条件下,枝条的长度有显著差异,而枝条鲜重无显著差异;不同径级下,枝条长度差异明显,而枝条鲜重没有显著差异。不同光照条件下,叶片的数量和鲜重均有显著差异;不同径级下,叶片数量没有显著差异,而叶片鲜重差异明显。生殖构件与营养构件间的异速生长关系不显著,体现了构件间生长关系的复杂性。

摘  要：
In order to explore the features of the Betula platyphylla population annual modules, and learn about their survival strategies and response to environment, the study analyzed modules under different light conditions and diameter classes through measuring the quantity and biomass of every module and relationships of all modules. The results showed that under different light conditions stem length had significant differences but stem fresh weight had no significant differences; under different diameter classes, stem length had significant differences, whereas stem fresh weight had no significant differences. Leaf quantity and leaf fresh weight had both significant differences under different light conditions; under different diameter classes, leaf quantity had no significant differences, whereas leaf weight had significant differences. The allometric relationship between reproductive modules and vegetative modules had no significant differences, which showed the complexity of growth relationship among modules.
