| 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 ｅｌｉｏｔｔｉｉ）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

| 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. |
