摘　　要：本文论述了西双版纳热带植物标本园引种的３２科６６种珍稀濒危植物迁地保护情况。在引种过程中，进行了生物学特性及抗性观察，对珍贵用材树种作了栽培和野生条件下的生长量比较以及龙脑香科植物的种子含水量测定和种子发芽试验。大多数树种的生长抽梢期在月平均温１７．５～２５．３℃的２～５月，开花期在月平均温２０．３～２５．３℃的３～５月，果熟期在３～４月和６～８月。This paper discusses the immigration protection of 32 families,66 genera of rareand endangered plants which introdueed in Xishuangbanna Tropical Botanical Garden. Ac.cording to the investigation of biological characteristics and resistance, compared the incre。ment of valuable wood species,which treated by diffrent conditions(cultivated and wild),and experiment on water content and gennination of Dipterocarnaceae,The result showsthe most species which growth and sprouting from Feburary to May,while mean tetnpera.ture is 17.5～25.3℃,flowering from March to May while mean temperature is 20.3～25.0℃,the fruit mature period is from Match to April and from June to August。
