加勒比松引种到广西,表现较好,但不同种源生长差异较大,为选择最好种源,1984年进行了三种加勒比松9个种源的引种试验。5年观察初步表现以巴哈马加勒比松2个种源表现好,高、径分别比当地马尾松大100—114.3%,155.5—174.1%,抗病虫能力比其它种源强。正种加勒比松表现亦较好。以上两种均可在广西南部地区推广。 The introduction of Caribbean pine to Guangxi, performed better, but the growth of different provenances is quite different. In order to choose the best provenance, three provenances of nine Caribbean pine were introduced in 1984. The results of 5 years observation showed that the two provenances of Bahamas caribbean pine showed good, high and diameter 100-114.3% and 155.5-174.1% higher than that of the native masson pine, respectively, and had stronger resistance to pests and diseases than other provenances. Positive species of the Caribbean pine also performed better. These two are available in southern Guangxi promotion.
