欧洲云杉、黑云杉、白云杉苗期对比试验

Comparative Test on the Seedling Stage of Picea abies, Picea mariana,Picea glauca

选择欧洲云杉3个种源、黑云杉3个种源、白云杉3个种源、青海云杉1个种源进行了不同种、种源的苗期生长性状变异试验。结果表明:云杉不同种、种源间苗期性状差异显著。4个种的1年生苗以苗高进行排序:欧洲云杉>黑云杉>白云杉>青海云杉。欧洲云杉、黑云杉、白云杉各个种的不同种源间有很大的变异及选择潜力。因此在进行云杉引种时,应选择不同的种、种源,才能取得更好的效果。

The experiment was carried on the seedling stage traits variation of the different species and seed sources： three Picea abies seed sources, three Picea mariana seed sources, three Picea glawca seed sources and Picea crassifolia seed source. The results showed： seedling stage traits of different spruce species and seed sources were different significantly. The seedling height of four species of annual seedling was ranked as follows： Picea or hies 〉Picea mariana 〉 Picea glauca〉Picea crassifolia. Picea abies, of different species Picea mariana and Picea glauca seed sources have great potential of variation and selection. Therefore, different species and seed sources of spruce were introduced to achieve better effect.
