According to several reviews that summarize the genetic diversity of plant species in relation to their life-history and ecological traits, forest trees have more genetic diversity than annuals or herbaceous perennials at both the population and species levels. In addition, the among-population genetic diversity in trees is significantly lower than most herbaceous perennials and annuals. Possible reasons why trees maintain relatively higher within-population genetic diversity than herbaceous perennials and annuals have not been critically discussed. Here, we discuss this observation in the context of the conservation of trees vs. herbaceous species and the reforestation and restoration of denuded areas. We recommend that guidelines and conservation genetic strategies should be designed differently for tree species vs. herbaceous perennial and annual species.

在保护策略中纳入树木和草本植物遗传多样性之间的差异

根据总结植物物种遗传多样性与其生活史和生态特征相关的若干评论，林木在种群和物种水平上都比一年生植物或多年生草本植物具有更多的遗传多样性。此外，树木的种群间遗传多样性明显低于大多数多年生草本和一年生植物。树木比多年生草本和一年生植物保持相对较高的种群内遗传多样性的可能原因尚未得到严格讨论。在这里，我们在树木与草本物种的保护以及裸露地区的重新造林和恢复的背景下讨论这一观察结果。我们建议指南和保护遗传策略应该针对树种和其他物种进行不同的设计。多年生和一年生草本植物。文章影响声明：指南和保护遗传策略应针对树种与多年生草本和一年生树种进行不同的设计。本文受版权保护。版权所有。
