| 摘 要： | 收集海南省儋州市、云南省西双版纳傣族自治州、中国香港、新加坡、越南河内市的5个雨树(Samanea saman)种源,分析了不同种源在湛江市遂溪县的苗期及造林早期生长表现.结果表明,不同种源雨树造林早期生长差异极显著(P<0.01);其中新加坡种源早期生长综合表现最佳,2.5 a生树高均值达3.56 m,地径均值达4.68 cm;5个种源2.5 a生平均保存率为72.12%,保存率较低,主要是因为受2015年强台风的影响.

| Abstract: | This paper studied the seedling and early growth proformance of different provenancesin Suixi county of Zhanjiang city, and the 5 experimental Samanea samanspecies were collected from Danzhou Hainan, Xishuangbanna Yunnan, Hong Kong China, Singapore, and Hanoi Vietnam. The results showed that the early growth performance of different S. samanprovenances showed extremely significant difference(P<0.01), in which the provenances from Singapore showed the best overall performance,the tree height was 3.56 m, and average ground diameter was 4.68 cm. The average preserving rate of 5 provenances of 2 and a half year old was 72.12%, and the low preserving rate was mainly due to the strong typhoon in 2015. |
