摘要
本文对我国云南西南部滇缅热带雨林中的野生龙眼与现代栽培龙眼进行比较研究,从遗传性状与生态环境的相关性论证了龙眼“原生种”、“中间型”和“进化型”的形成,并根据其比较稳定的遗传性提出中国龙眼属植物分种检索表。
This paper presents some comparative studies between the cultivated varieties of Dimocarpus longan and its wild species which are found in the tropical rain forest of south-western Yunnan and Burma. The writer discusses the formation of the original species, intermediate variety, and the highly evolutionary variety based on the relationship between genetic charasteristics and ecological environment, and he proposes a key of Dimocarpus species in China in the light of the relative stable genetic characters.
