摘要: 本文系统地研究了中国松属单维管束松亚属、双维管束松亚属木材管胞内表面及纹孔表面的疣状层特征。研究表明,疣状层的有无是区分针叶树木一些科、属(及亚属),种的重要标志。同时,还结合木材解剖特征、木材化学特性及有关树木形态对白皮松(组)的分类单位问题进行了详细讨论并提出了商讨意见。

Abstract: This paper shows that warty layers are not easy to be seen,or appear occasionally on the corner of inner surface of tracheids in Subgenus Haploxylon(Softpine)except Section Parry Mayr.but appear commonly on the inner surface of tracheids and the surface of pit border and pit chamber in Subgenus Diploxylon(Hardpine).It is an important characteristic of identification among subgenera,genera,and families in conifers.It is very easy to separate the warty layer from the neighboring layer,the inner layer or the outer layer of secondary wall in the part of pit border,and the inner layer of secondary wall. Warty layers are appeared clearly in the inner surface of tracheid and parts of pit in Pinus bungeana of Subgenus Haploxylon.It is very different from the other species of Haploxylon pines which have their own features.The author has made a systematic study and suggested to establish a new Subgenus Parry based on its gross and anatomical characteristics,ultrastructure,morphology of tree,and some aspects of chemotaxonomy.
