摘要
根据红皮云杉三个代表参试点10年生种源试验的材料,在研究其地理变异规律的基础上,以子代的生长、形态和适应性等综合性状的主分量分析结果,气候区划的验证,将红皮云杉的天然分布区划分为三个种源区,即穆棱种源区(Ⅰ)、伊春种源区(Ⅱ)、黑河种源区(Ⅲ)。
By the principal component analysis and variance analysis on typical characters, such as offspring's growth, morphology and adaptability of nine provenances from three ten-year-old provenance trials, three provenance districts have been made in the natural distribution area of Picea koraiensis as follows: the provenance district of Muling (№. 1); the provenance district of Yichun (№.2); the provenance district of Heihe (№.3); Mean-while, it gives a brief introduction to general situation of each provenance district.
