摘　　要：用产于加拿大9个种源的扭叶松种子育苗,在湖北恩施的建始县国有高岩子林场的十字坪、姚家坡进行了扭叶松不同种源地、不同种源的植苗造林试验.其幼树期的试验结果表明:扭叶松能适应两地的环境条件,植苗造林成活率及保存率达91.3%～100%;对14年生的试验林进行高、径生长分析,扭叶松的树高生长和胸径生长受种源、造林地点的影响极显著;种源与造林地点对树高生长的交互作用极显著.进一步对树高进行单点分析,参试的9个种源,在十字坪试点,10577、26230、25730、27084、28476、14726、26153七个种源的树高生长极显著高于25801、25803两个种源,且7个种源两两间差异不显著;姚家坡试点10577种源的树高生长极显著高于其他种源,其下依次是28476、26153、26730、27084、14726五个种源.胸径生长在种源间的极显著差异缘于10577种源与25803、25801种源间的差异,其他任意两种源间的胸径生长差异不显著.Using the Pinus contorta seeds of nine provenances from Canada, planting experiment of Pinus contorta was conducted at Shiziping and Yaojiapo in Gaoyanzi forest farm of Jianshi county, Hubei province. The growth performance of sapling stage showed that Pinus contorta could adjusted to the site conditions of the two experimental sites. The survival ratio and preserving ratio reached 91.3%-100%. The height growth and DBH growth of 14 years old experimental forests were analyzed, the results showed that the height growth and DBH growth of Pinus contorta were very significantly affected by proverbance and planting site, and there was very significant interaction between provenance, planting site and tree height growth. Among the 9 provenances, the tt.ee height growth of 10577, 26230, 25730, 27084, 28476, 14726, 26153 was very significantly higher than that of 25801 and 25803. There was no significant difference between every, two provenance of the seven provenances. At Yaojiapo experimental site, the tree height growth of 10577 was very significantly higher than other provenances, next in order of 28476, 26153, 25730, 27084 and 14726. The difference of DBH growth among provenances was rooted in the difference between 10577, 25803 and 25801, and the difference between every other two provenances was not significant.
