| Abstract: | Pinus caribaea is one of the famous fast-growing conifer species. This provenance trial includes a lot of provenances from three subspecies of pinus caribaea which has widely been planted in China. The results are as follows:(1) During young tree stage, Pinus caribaea var. bahamensis is the fastest growing one among the three subspecies, the next one is Pinus caribaea var. hondurensis. (2) In provenance level, the best provenance from Pinus caribaea var. bahamensis is NO. 1/79, after five years growth, average height of the provenance is 6.6m,average breast height diameter 11.5cm, average volume of single tree 0.0343m3. (3) The best provenance from Pinus caribaea var. hondurensis is NO. 12/78, average height is 5.4m, average breast height diameter 10.8cm, average volume of single tree 0.0247 |
