| 摘要: |
| 于1983年、1984年在广西南宁地区林业科学研究所引种美国8个州47个湿地松(Pinus elliottii)种源。以广东台山湿地松种子园、安徽马鞍山火炬松(Pinus taeda)和本地马尾松(Pinus massoniana)为对照。采用随机区组设计,重复4次或5次,试验表明,湿地松种源间生长差异显著,其生长性状的变异属地理渐变型,其它性状的变异则属随机型。优良种源主要分布在美国路易斯安那州到佛罗里达州狭长地带。影响湿地松生长的主要气候因子是年平均气温、1月平均温度和年降雨量。 |

| Abstract: |
| Slash pine(Pinus elliottii) provenance tests with 47 provenances from 8 states of the United States were conducted in Forestry Research Institute of Nanning Prefecture, southern China from 1983 to 1984. Taishan slash pine of Guangdong province, Pinus taeda of Anhui province and local Pinus massoniana were applied as controls. A randomized block design with 4 or 5 duplications was used. It showed significant variations among different provenances of slash pine. The growth variance of slash pine was geographic-gradual change, the others changed randomly. The superior provenances distributed from Louisiana to Florida. The main climate factors influencing growth of slash pine are average annual temperature, average temperature in January and annual rainfall. |
