摘  要:
收集云南普洱、台湾台北、云南西双版纳、广西凭祥、广西北海5个铁刀木(Cassia siamea)种源,比较分析了不同种源铁刀木的早期生长表现。结果表明,不同种源铁刀木早期生长差异显著(P<0.05),其中以广西凭祥种源生长综合表现最佳,2 a生树高均值达2.73 m,地径均值达4.08 cm。5种种源保存率均较高,造林当年成活率达97%以上,且种源间差异不显著。

摘  要:
The early plantation stage growth status of five provenances of Cassia siamea, which from Puer Yunnan, Taibei Taiwan, Xishuangbanna Yunnan, Pingxiang Guangxi, Beihai Guangxi, was studied in this paper. The results showed that early growth performance of different C. siamea provenances were significantly different, in which the provenance from Pingxiang Guangxi showed the best overall performance. All the preserving rate were high, which reach more than 97% in the first year. Moreover, no significant difference of preserving rate between them was found.
