几种木兰科植物遗传多样性研究进展

生物多样性的研究和保护是当今世界普遍关注的问题，遗传多样性是生物多样性的重要组成部分。在被子植物中木兰科植物受到严重威胁的种类最多，且部分是中国濒危稀有植物，研究其遗传多样性具有重要意义。文章综述了木兰科重要属、种的遗传多样性研究进展，并根据国内的研究现状，对今后木兰科植物的保护工作提出建议。

Advances in Research on Genetic Diversity in Several Species of Magnoliaceae

Conservation of biodiversity is a major issue of concern within the international community,and genetic diversity,the basis of species diversity and ecosystem diversity,are the most important research areas.As the Chinese distinct plant,Magnoliaceae suffers the most among Angiosperm.The understanding of its genetic diversity is critical for both theory and application.This essay reviewed the progress in research on genetic diversity in several species of Magnoliaceae.Several suggestions were proposed according to the latest research.
