辽东半岛不同生境结缕草无性系种群构件生物量结构

Biomass structure of modules in Clonal Population of Zoysia japonica in different habitats in Liaodong peninsula,China

按生物构件理论,分析了4个不同生境中结缕草Zoysia japonica无性系种群叶片、叶鞘、分株、匍匐茎各构件生物量和总生物量的特性和结构。结果表明,不同生境间结缕草无性系种群性状数量具有较大的生态可塑性,总生物量最大的为1 080.27 g/m2,最小的为225.35 g/m2,二者相差4.7倍。不同生境结缕草无性系种群构件生物量结构反应了不同生境种群不同的生物量分配策略,这是种群对其生境适应的结果。

The paper analyzed the quantitative characters and structure of the biomass of leaf, leaf sheath, ramet and creeping stem-modules in clonal populations of Zoysia japonica in Liaodong peninsula of China. The results showed that there was significant ecological plasticity in quantitative characters among 4 different habitations. The biomass structures of modules changed in different habitations and reflected the allocation patterns, which resulted from adapting them to the habitat.
