| 摘 要： | 通过12年的火炬松种源试验研究表明，火炬松种源生长性状差异极其显著，12年生平均树高、胸径和树高中央直径分别比对照马尾松大40．2％、78．8％和103％。千粒重与地理位置基本无相关，但却与生长性状相关显著。早期选择应该从造林后开始选择，已初步选出了11，4，20，17，5，15和25号种源作为安康浅山地区发展的优良种源。

| Abstract: | Twelve-years test for Pinus taeda shows that significant differences existed in growth among different provenances. The averaged height, diameter at breast height(dbh) and middle diameter for 12-year growth are 40.2%,78.8% and 103% greater than those of Pinus massoniana. Weight of 1000 seeds is not related to geographical position, but significantly related to growth characters. Early selection should begin after a forestation. the provenance of No.11, 4, 20, 17, 5, 15 and 25 have been selected as the excellent provenance for the development in the hilly region Ankang. |
