峨眉山八角莲属植物的生态学与生物学特性研究

THE STUDY ON ECOLOGICAL AND BIOLOGIC CHARACTERS OF THE GENUS DYSOSMA IN MOUNTAIN EMEI

摘要: 本文对蛾眉山八角莲属植物的种类分布、生境和生物学特性进行了研究,结果表明,①蛾眉山八角莲属植物5种1变种,原始及变异类型分布集中;②种间垂直替代现象明显,对于阴湿环境及肥沃、酸性、多砾质土壤环境反应出一定程度的共同要求;③不同种类在生长节律、特性、花粉育性、花粉发芽条件以及自然繁殖能力等方面存在一定差别;④人工根插繁殖可提高本属植物的繁殖系数。

Abstract: This paper deals with the distribution, habitat and biologic characters of Dysosma in Mt, Emei, The results show: 1. In the five species and one variety, there are primitive and advanced forms, It indicates that Mt. Emei is one of the centers of distribution and diversity of the genue. Dysosma; 2. There is obviously a vertical replacement between the species. All of the species prefer the habitat of shady with rich, acid and polygravel soil; 3. There are some differences among the species in growth rhythm and biological characters, pollen fertilitiness and germination condition and natural reproductive potential; 4. The reproductive rate can be increased by root-cutting.
