摘 要: 综述了国内外植物生态型分类的研究进展,介绍了一些常用的分类指标:形态指标--外部形态指标和内部形态指标,生理指标--光合速率和内源激素,生育期指标,化学成分,抗逆性--逆境和受污染环境,遗传指标--同工酶和随即扩增的多态DNA(RAPD)等,并根据国内外植物生态型分类研究进展,结合我国生态型分类研究现状,对我国植物生态型分类的研究前景进行了展望。 Summarized the studies of plant ecotype classification. The commonly used indexes are recommended: morphologic indexes including exterior morphologic indexes and interior morphologic indexes, physiological indexes including photosynthesis ratio and endogenetic hormones, reproduction period indexes, chemical components, resistance-adversity and polluted environment, heredity indexes including isozyme and random amplified polymorphic DNA (RAPD). Expectation of plant ecotype studies was put forward according to the research advances of our country in plant ecotype classification.
