与种子传播、无性系和芽库有关的性状影响着植物物种的成败。利用来自不同人类生境的13个演替序列的数据，比较了与扩散和持久性相关的性状谱，以确定可用于预测演替中每个阶段特定植物物种发生的性状，以及这些性状的重要性如何随时间变化。研究了与初级演替和次级演替相关的物种性状差异。在演替过程中，种子通过水传播的物种（水生植物）的丰度减少。主根分裂、单环和双环芽的种类也减少了。能够形成潜在地下芽库、地下根茎并与无性系后代保持长期联系的物种数量增加。结果表明，在演替的早期阶段，种子传播对物种组成的决定更为重要，而在演替的后期阶段，芽库和无性系性状对定殖更重要。初级序列和次级序列在物种的性状谱上没有显著差异，表明这种趋势在两种演替类型中都存在。
Traits related to seed dispersal, clonality and bud bank affect the success or failure of plant species. Using data from 13 successional seres in various human-made habitats the spectra of traits associated with dispersal and persistence were compared to determine the traits that can be used to predict the occurrence of particular plant species at each stage in a succession and how the importance of these traits changes over time. Differences in the traits of species associated with primary and secondary successions were also studied. Species with seeds that are dispersed by water (hydrochory) decreased in abundance during the course of succession. Species with a splitting main root, monocyclic and dicyclic shoots also decreased in abundance. Species capable of forming a potential below-ground bud bank, hypogeogenous rhizome and retaining a long-term connection with clonal offspring increased in abundance. The results indicate that seed dispersal is more important in determining the species composition in the early stages of succession whereas bud banks and clonal traits are more important in the later stages and for colonizing a locality. Primary and secondary seres did not remarkably differ in the trait spectra of the species present indicating that these trends occur in both types of succession.
