| 摘 要： | 朱缨花属（Calliandra Benth.）植物全球约125种,其中细叶粉扑花（Calliandra brevipes）、红粉扑花（Calliandra emarginata）和朱缨花（Calliandra haematocephala）等较为常见。通过对3种朱缨花属植物扦插幼苗的形态指标和生物量进行测量,采用多重比较和相关分析,研究同属植物间的差别和共性。结果表明：3种朱缨花属植物地下部分根的生长较为相近,根冠比差异不显著,但不同植物生物量的大小存在较大差异;根长、高径比（株高与地径的比值）与生物量不存在显著的相关性;地上、地下与总生物量之间相关性显著,其中又以地上部分生物量与总生物量的相关性较强。

| Abstract: | Calliandra Benth. have about 125 species of plants in the worldwide. Among them, Calliandra brevipes,Calliandra emarginata and Calliandra haematocephala are very common. In this article, three species of cutting seedlings of Calliandra B. were selected to measure their morphological index and biomass. Multiple comparison and correlation analysis were used to study the differences and similarities between the same genuses. The results showed that： the growth of the belowground root length of the plants was more similar and root-shoot ratio was not significant, but different plants have different root number or plant height, so the biomass of each other was still varies. Furthermore, there was no significant correlation between biomass and root length, and height： diameter ratio.Finally, the total biomass with its parts was significantly correlated as well as themselves, of which the aboveground biomass and the total biomass have a stronger correlation. |
