摘要
植物的功能性状是植物生态学领域近年来研究的热点内容之一.其中,植物叶功能性状与植株生物量、植物对环境资源的获得及其利用的关系最为密切.研究淮北相山5种优势植物叶干物质含量、比叶面积及其相互关系,显示不同物种间的叶干物质含量、比叶面积存在显著差异,两种叶性状间存在明显的负相关关系.依据比叶面积的大小,初步判断5种植物对相山的适应性顺序为柘树<扁担木<牡荆<酸枣<构树.
In recent years, plant functional trait has become a hot topic in ecological research, of which leaf functional trait is most closely related with plant biomass, resource acquisition and utilization, and resource use efficiency. In this study, leaf dry matter content （LDMC）, specific leaf area （SLA） and their relationship were studied in Xiangshan mountain of Huaibei city. Variance analysis showed that there were significant differences among five species in LDMC and SLA（P〈0.05）. Pearson correlation analysis showed that specific leaf area （SLA） was negatively correlated with leaf dry matter content （LDMC）. Based on the values of specific leaf area （SLA）, It is concluded preliminarily that the adaptive ability of five species to Xiangshan mountain environment increase as the sequence Cudrania tricuspuidata〈Grewia biloba var. parviflora〈 Vitex negundo var. cannabifolia 〈 Ziziphus juj uba var. spinosa〈Broussonetia papyrifera.
