摘  要:
对玉龙雪山龙胆科1年生植物椭圆叶花锚2个种群的花期繁殖分配进行观察发现:其资源分配存在个体大小依赖性,且繁殖分配将近占了总投入的一半,种群间的资源分配模式没有显著性差异。结果显示,该物种花数量随个体大小增大而快速增多,表明1年生植物个体寿命有限,繁殖的意义远大于其他功能,其资源分配模式不因生境改变或恶劣而产生异质性,也不受种群密度的影响。

摘  要:
This paper investigated the reproductive allocation of two populations' therophyte Halenia elliptica in flowering phase in Jade Dragon Snow Mountain.The results showed that it was size-dependent in resource allocation,and the reproductive allocation occupied nearly half of total investment.The rapidly increase of flower number with individual size indicated that the reproduction was more important than other function in the short lifespan of therophyte,that there were no heterogeneity patterns of resource allocation in different or severe habitat,and that the population density had little effect in allocation pattern.
