【摘要】 本文用方差分析区别具台木类木材的三个种:太原台木(Dadoxylon taiyuanensis)、生根无髓根(Amyelon radicans)和徐氏无髓根(A.xui),并同国外的种比较。结果表明,用这种方法能定量地研究植物性状之间的区别,并得到较好的效果。更多还原

【Abstract】 This paper suggests that the analysis of variance could be used to the distinction of Da- doxylon-like woods and some quantitave characters of Dodoxylon taiyuanensis,Amyelon radi- cans,A.xui,A.equivius and Billigea resinosa,for example.,diameter of ray ceils and tracheids, height of rays,and diameter ratio of ray to tracheid,are compared and discussed. The comparision and discussion show quantitave character is more useful to identification of fossil plants than others if analysis of variance is used.更多还原
