摘要:
 对5种龙船花属植物幼苗生长过程中的形态特征和生物量的积累情况进行了测量和统计分析。结果表明，幼苗的根长与地下生物量、地上生物量与地下生物量存在显著的相关性（p<0.01），其中同属不同种的植物在同一年龄阶段，不同器官的生物量不同；同种不同变种、变型的植物，其生长的一致性则较高；橙红龙船花（Ixora coccinea var. coccinea）和黄龙船花（I. coccinea var. coccinea f. lutea）具有较大的根冠比，生长迅速；而邦德胡卡红仙丹草（I. coccinea var. bandhuca）比叶面积较大，截获光的能力更强；龙船花（I. chinensis）、橙红龙船花和矮龙船花（I. williamsii ‘Sunkist’）较耐瘠薄，有利于在非理想环境中应用。
Abstract:
Ixora plants are typical tropical flowering shrubs with bright colors and long florescence.It is critical to accumulate biomass for plants vegetative growth at the stage of seedling.In this paper,measurement and statistical analysis were carried out on the morphological characteristics and biomass accumulation of 5 species of Ixora plants during their seedling growth.The results showed that there was a significant correlation (p< 0.01) between the root length and underground biomass, the aboveground biomass and underground biomass.Thereinto,the biomasses of different organs of different varieties within the same the plant species and same ages were different. However,the growth of different varieties and forma had higher consistency.I.coccinea var.coccinea and I.coccinea var. coccinea f.lutea having a large root-shoot ratio grew rapidly,but the specific leaf area of I.coccinea var.bandhuca was larger,so the ability of capturing light was stronger,and the barren resistance of I.chinensis,I.coccinea var.coccinea and I.williamsii ’Sunkist’ was higher,which was conducive to the growth of the plant in poor environments.The article provides a useful reference data for the selection,configuration and fertilizer management of Ixora plants.
