摘要:
为了揭示锡兰龙脑香在中国热带地区的适应性，丰富我国珍贵的优良的树种资源。中国科学院西双版纳热带植物园于1997年引种产自斯里兰卡南部的锡兰龙脑香种子，经28 a的引种栽培观测表明。该树种在引种地生长迅速，年均生长量分别为1.06 m和1.85 cm，特别是在造林5 a后，生长极为迅速，树高连年生长量超过1.1 m，胸径连年生长量超过2.5 cm，与同一立地条件下栽培的其他国产龙脑香科树种相比，径粗生长超过任何一种树种。生长期较长，一般从2月初开始抽梢生长，至11月下旬12月初停止生长；开花结果正常，栽培后15 a就开始开花结果，花期为4月中旬至5月中旬，果熟期为7月上旬至8月中旬。种子寿命短，不耐储藏，在自然条件下随着存放时间的延长，种子含水量和发芽率随之急剧下降。新鲜种子发芽率不高，为48.33%，利用种子已繁殖出一批新植株。表明该树种在西双版纳低海拔地区具有较好的适应性，能正常的开花结果，并且后期生长较快，适宜培养大径级材的速生优质用材树种。
Abstract:
In order to reveal the adaptability of Diptercarpus zeylanicus in China tropical area and enrich the resorces of costly and fine wood species. D. zeylanicus was intriduced from siuthern of Srilanka into Xishuangbanna Tripical Botanic Garden, Chinese Academy of Sciences in 1977. It was observed that the annual mean hgight and mean diameter at breast height(DHB) of 28 a trees were 1.06 m and 1.85 cm respectively, the height and DHB in successive years were more than 1.1 m and 2.50 m respectively after planting 5 a especially. Annual mean DHB increased faster than other Dipterocarpaceae species planted in same condition. The growth periods was long, lasted from February December. The flowering and fruiting of the plant were aterted after planing 15 a, flower time was from at the middle of April to the middle of May, fruit mature time was from early July to middle August Nature life of seed was very short, and the storage seed was very difficult. The moisture and germination of seed decreased quickly along with the storage time. The germination of fresh seed was not high, only 48.33%. New generations of the plant had heen propagated seeding. The rusults of intoduction showed that the plant grew very fast, and the flowering and fruiting of the plant were normal, it is a valuable tree with quality timber, and satisfactory to develop timer with big DHB.
