摘要
比较杉木与峦大杉、秃杉与台湾杉幼材组织主要结构的数量及各自间的比值， 探索其种间和种内的关系． 从早、晚材管胞长度、径向宽、壁厚及腔径等比值以及各自纹孔的数量、纹孔口／纹孔缘的比较结果均表明：台湾杉与秃杉间的差幅，仅相当于峦大杉和杉木间差幅的１／１０～１／２， 其中纹孔密度的差幅则约１／３０． 轴向薄壁组织和射线， 在台湾杉和秃杉中的分布、密度等数量组成也甚为接近，其细胞长度差幅分别为±１０、±４μｍ ， 而在峦大杉和杉木中则分别相差５０、２８μｍ ， 因此，
In order to seek the relationship of interspecies and intraspecies between C lanceolata and C konicahii,T flousiana and T cryptomeriodes,their young timber's quantities of main structure and the ration were compared.The results showed that the difference between C lanceolata and C konicahii was 1/10~1/2 of those between T flousiana and T cryptomeriodes,and the density of pit was only 1/30.The distribution and the density of axial parenchyma and the ray in the C lanceolata and C koniahii timber were same,and the difference in cell length was only ±10μm and ±4μm,respectively.However,those difference between the T flousiana and T cryptomeriodes timbers was up to ±50μm and ±28μm.So,it should be proper to think that C lanceolata and C konicahiiwas the same tree species that had the ecological difference for the different seed source.
