| 摘 要： | 根据植物标本鉴定工作的实际需要,从植物的外部形态及解剖结构入手,采用多元统计分析方法对分布于内蒙古赤峰市克什克腾旗的蒙古云杉(Picea meyeriRehd.et Wils.var.mongolicaH.Q.Wu.)进行了比较研究。结果认为:云杉叶的气孔线、树脂道很难作为分种依据,而小枝颜色、毛被、有无白粉,球果大小,叶尖等性状可以作为分种依据,并指出白音敖包沙地的云杉不宜将其独立为种,即沙地云杉(Picea mongolica(H.Q.Wu)W.D.Xu.),而同意作为白杄的一个变种——蒙古云杉。

| Abstract: | According to plant specimen identifying needs,the plant's outside morphology and anatomy structure were studied.Multivariate statistical analysis method was adopted to carry out comparison research on the Picea meyeri Rehd.et Wils.var.mongolica H.Q.Wu collected in Keshiketeng banner of Chifeng.The results showed: the properties such as the branchlet′s colour,piliferous,cones can be considered as the basis of identifying species,but not the stomatic band and resin gland of Picea leaves.It is pointed out Picea of sandy land are not the independent species(Picea mongolica(H.Q.Wu)W.D.Xu),but a variation of Picea meyer-Picea meyeri Rehd.Et Wils.var.mongolica H.Q.Wu. |
