| 摘要: |
| 分别于1987年和1988年在广西南宁地区林业科学研究所进行洪都拉斯变种的种源试验。结果洪都拉斯加勒比松种源间幼林生长差异显著,但随着林龄增加,差异减小。干形的选择改良效果明显,树种对比试验的生长排序为洪都拉斯变种(P.caribaea morelet var.hondurensis) > 巴哈马变种(P.caribaea morelet var.bahamensis) > 湿地松(P.elliottii) > 马尾松(P.massoniana) > 马斯特松。 |

| Abstract: |
| The provenance test on Pinus caribaea var. hondurensis was conducted in Nanning Prefecture Forestry Research Institute,Guangxi, southern China from 1987 to 1988. There were significant differences between provenances of Pinus caribaea var. hondurensis at young growth, but as age increased, the variances reduced. The improvement on stem form was obvious. Different species in growth was in the order of Pinus caribaea var. hondurensis, P. caribaea morelet var. bahamensis, P. elliottii, P. massoniana and mast pine. |
| Key words: P.caribaea morelet var.hondurensis provenance species |
