摘要
利用从美国引进的3种云杉的不同种源,以乡土树种红皮云杉作对照进行优良种-种源选择研究。结果表明,欧洲云杉与黑云杉相比,树高、胸径和材积差异均达到极显著水平;与白云杉和红皮云杉相比,树高差异达到显著水平,是引种成功的优良树种。选择欧洲云杉为优良树种,树高的遗传力为54.0%,遗传增益为8.0%;胸径的遗传力45.6%,遗传增益为9.3%;材积的遗传力为38.3%,遗传增益为24.9%。同时,选出了白云杉1号(北纬40°20′、西经74°00′)和白云杉3号(北纬39°00′、西经75°00′)种源为优良种源,直接引种欧洲云杉和白云杉优良种源应用在造林、绿化中可获得显著的增产效益。
Utilizing 3 species of spruce that introduced from USA, studies of selection of species and provenances were carried out by means of native tree species Korean spruce as the control. The results showed that： there were significant differences in tree height, DBH and volume between European spruce and black spruce, there were differences in tree height of European spruce in comparison with white spruce and Korean spruce. Introducing European spruce as superior tree variety was successful. European spruce was selected as a superior tree species, the heritability was 54.0 percent, genetic gains were 8.0 percent; the heritability of DBH was 45.6 percent, genetic gains were 9.3 percent; the heritabillty of volume was 38.3 percent, genetic gains were 24.9 percent. Meantime, white spruce No. 1 （N 40°20′, W74°00′） and No. 3 （N39°00′ ,W75°00′ ） were selected as superior provenances. Application of introduced European spruce and superior provenances of white spruce on afforestation and greening would obtain remarkable benefits.
