| 摘 要： | 对引进的欧洲云杉、西加云杉、白云杉、黑云杉以及国内的川西云杉和青海云杉的24个不同种和种源生长及分枝性状进行早期(8年生)测定与评价.结果表明:5年生长期内生长及形态性状在不同的云杉种间和种源间的差异多数达到极显著或显著水平,且种和种源的方差分量分别占总方差分量的32.47％和23.97％,证明不同种间和种源间存在较大的遗传变异.通过多重比较和相关分析发现,国外的云杉种较国内种在生长表现和适应性上均有明显的优势.经性状相关分析得知:各个生长及形态性状之间均存在极显著的正相关关系,尤其是苗高与各分枝性状之间的相关系数均值为0.825 9.最后利用苗高为主要指标初步筛选出6个优良种源,人选的种源均表现出明显的优势,其中苗高、侧枝总数以及当年侧枝数的平均值分别为117.07 cm、57.75、12.46,均分别比对照种源的总平均值高48.54％、56.46％和63.30％.

| Abstract: | Early evaluation experiments in twenty-four provenances of Picea abies, P.sitchensis, P. glauca, P.mariana, P.likiangensis (Franch) Pritz var. balfouriana (Rehd.et Wils.) Hillier ex Slavin and P.crassifolia were carried out. The results showed that there existed very significant or significant differences in most of growth and lateral branch traits among species and provenances of young forests, and the average variance component of species and provenances accounted for 32.47% and 23.97% of total variance component respectively, all of which indicated that there were high genetic variations among species and provenances. Moreover, there was a extremely and obviously positive relationship between growth and lateral branch characteristics by correlation analysis, especially the plant height and lateral branch traits, their average value of correlation coefficients was 0.825 9. As a result of this research, six excellent provenances of spruce were selected tentatively on the basis of plant height. All of these superior provenances had distinct predominance in growth, their average values of plant height, total number of lateral branches and the number of newest lateral branches were 117.07 cm, 57.75 and 12.46, respectively, which were 48.54%, 56.46% and 63.30% higher than the overall means of contrast spruce provenances. |
