Meanwhile, we highlight several research corners for future further study, the trade-offs on resource allocation within perennial plant had not been proved, the relationship of neighbor effects and reproductive allocation was still not so clear for individual plant, there was no definite conclusion on perennial plant reproductive strategy under different neighbor effects and different habitats. The relationship between reproductive allocation and sexual allocation , the cause of resource distribution in anthotaxy structure, the similarities and differences of reproductive allocation and the maintain mechanism within all kinds of reproductivest rategy need a further investigation. In addition, a molecular study is required for explaining the variation mechanism and the biological meanings on seed size research.

指出生活史研究仍存在不足首先是研究内容上，资源分配在多年生植物中的权衡仍未被有力证明，邻体效应与繁殖分配的关系在个体水平上仍不明了，多年生植物在不同邻体效应和生境下将采取何种繁殖对策目前尚无明确的结论；繁殖分配与性分配之间的关系，引起花序结构上资源分配差异的原因，各种繁殖对策中繁殖分配异同与维持机制等问题仍有待于进一步的研究；种子大小的变异机制以及生物学意义仍未得到令人满意的答复，更需分子水平上的研究来解释其机理。
