| 摘 要： | 本文对磐石县明城林场试验点４ａ生水曲柳幼林期种源试验林生长性状的方差分析及多性状的综合评定，初步确定吉林地区及毗邻地区优良种源为大海林（３２）、通化（０１）．估算树高、年树高生长量、地径遗传力分别为０．７３１２，０．６４４１，０．５４３３．若选择大海林、通化种源造林，树高、地径生长量可分别获得２４．３３％，１９．８％和２２．８５％，１８．７％的遗传增益。

| Abstract: | According to variance analysis and comprehensive evaluation of seeds prove-nance experimental forest of F.mandshurica with four years in the forest farm of Mingchen,the optirnum provenances of seed in Panshi county are dahai forest(32)and tonghua(01)inJilin area and nearby. The heritability of tree height, crement of annual height and D. G. His0.7312,0.6441 and0.5433 respectively. The inheritance enhancement(24.33%,19.8%and 22.85%,18.7%)are obtained by tbe use of dahai forest and tonghua as provenances ofseed on tree height and D. G. Hcrement. |
