| 摘 要： | 植物天然居群表型变异研究可以为植物遗传改良提供基础资料,也有助于了解植物适应性、探究其进化方式与机制,目前仍为许多学者所热衷。学者们似乎更倾向于通过天然居群表型变异研究探讨植物适应性及其形成机制。本文从植物适应性研究角度综述了表型变异的空间格局、亲代与子代表型变异的关系以及表型可塑性等热点问题,并且评述了我国天然居群植物表型变异研究现状。

| Abstract: | Studies on phenotypic variation of a plant species from natural populations can not only provide fundamental data for its genetic improvement,but also conduce to understand plant adaptability and probe into its evolution way and mechanism.It seems that investigation into phenotypic variation in natural populations is apt to be used by many biologist or ecologist as a way to research plant fitness and its formation mechanism.In this paper we review some hot issues in the field such as spatial pattern of phenotypic variation,relationship between phenotypic variations of parent and offspring,and phenotypic plasticity in terms of plant fitness,and assess the current research status in these fields in China. |
