本文论述了滇南热带植物多样性迁地保护区的建设与稀有濒危植物的保护。进行了种子贮藏与萌发、幼苗生长条件和不同栽培条件等试验以及生物学特性观察等。雨季成熟的大粒型种子一般不耐贮藏,中、小粒型种子较耐贮藏,细小种子耐贮藏。育苗中幼苗除强阳性树种不需遮荫外,大多数热带雨林树种幼苗和幼树期都需要一定的荫蔽条件才能生长良好。西双版纳热带植物的发芽、抽梢、开花高峰期都集中在日平均温达20℃左右的3月。大量开始落叶是在1～2月,3月为多数植物的落叶盛期。果实在干凉季（11～2月）成熟的占23.9％,干热季（3～5月）成熟的占36.4％,湿热季（6～10月）成熟的占40％。

This paper represents the construction on the ex situ  conservation area of tropical plant diversity in Southern Yunnan, and the protection on rare and endangered plants, mainly focuses on the studies of experiments for seed storage and germination, the living condition of seedlings, and varied cultivating conditions and their biological characters. The study shows that the big-sized seeds which matured in rainy season keep a short time in storage, small middle-sized ones keep longger and the smallest ones keep the longest. Most of the seedlings and young trees of tropical rainforest species need some shady conditions in raising period to grow well except the pioneer species. The sprouting, branching and flowering peak period of tropical plants in Xishuangbanna are concentrated in March which has a daily temperature of about 20%, and the deciduous period usually starts from January to February. March is the falling peak period for most of the plants. 23. 9% of fruits matured in dry and cool season (November-February), 36. 4 % matured in dry and warm season ( March-May ) , 40 % matured in humid and warm season (June to October).
