| 摘 要： | 在观察国产针叶树材中发现：１．杉松冷杉（ＡｂｉｅｓｈｏｌｏｐｈｙｌａＭａｘｉｍ．）的轴向管胞早材径壁有显然不同大小的二类具缘纹孔存在；２．落叶松属（Ｌａｒｉｘ）木材的射线薄壁细胞有主为长随圆形和主为等径形二类，据此可以区分落叶松组（ＳｅｃｔｉｏｎＭｕｌｔｉｓｅｒｉａｌｅｓ）和红杉组（ＳｅｃｔｉｏｎＰａｕｃｉｓｅｒｉａｌｅｓ）；３．西藏长叶松（ＰｉｎｕｓｒｏｂｏｕｒｇｈｉＳａｒｇ．）木材的射线管胞显著地较其它树种量多而低矮；４．金钱松（ＰｓｅｕｄｏｌａｒｉｘａｍａｂｉｌｉｓＲｅｈｄ．）的轴向薄壁细胞中，云杉（ＰｉｃｅａａｓｐｅｒａｔａＭａｓｔ．）、油松（ＰｉｎｕｓｔａｂｕｌａｅｆｏｒｍｉｓＣａｒ．）和冷杉（ＡｂｉｅｓｆａｂｒｉＣｒａｉｂ．）轴向管胞中有晶体存在。

| Abstract: | Some discoveries about anatomic features of Chinensis softwoods have been made. 1.There present two types of bordered pits on the radial walls (earlywood)of the axial tracheids in the Abies holophylla Maxim. 2.In the Genus Larix,Section Multiseriales can be distinguished with Section Pauciseriales by the ray cells ise diametric or approximately and elliptic respectively. 3.The Pinus robourghii Sarg. can be distinguised from other species of Pinaceae by the larger number and smaller size of the ray tracheids. 4.There present prismatic crystals in the axial parenchyma of the Pseudolarix amabilis Rehd. 5.There exist crystals in the axial tracheids (earlywood) of Picea asperata Mast.,Pinus tabulaeformis Carr.and Abies fabri Craib. |
