摘要: 应用石蜡切片技术及扫描电镜方法,对喀纳斯自然保护区生长的6种藓类植物茎、叶的内部结构及其表面的角质层纹饰、疣、孔等进行比较研究,结果表明:垂枝藓(Rhytidium rugosum(Hedw.)Kindb.)叶背、腹面表皮细胞外壁均有细疣状突起,而纵列相邻细胞的壁表面角质层纹饰长,成束状平行排列;山羽藓(Abietinella abietina(hedw.)fleisch.)茎的中轴不明显,中肋背部具棘刺状突起的疣,叶背、腹面的疣倒向凹陷的细胞壁,呈遮盖状;直叶珠藓(Bartramia ithphylla Brid.)叶背、腹面表皮细胞外壁具泡状隆起,孔不凹陷,孔口被角质层纹饰所遮盖;沼泽皱蒴藓(Aulacomnium palustre(Hedw.)Schwagr.)叶背面的粗疣由凹陷细胞壁中突出,角质层纹饰呈带状,叶腹面孔大,并多在细胞壁相交处呈张开状;塔藓(Hylocommium splendens(Hedw.)B.S.G.)叶背部粗疣呈宽刺状,叶背、腹面粗疣高,上端倒向凹陷的细胞壁;角齿藓(Ceratodon purpureus(hedw.) Brid.)叶背、腹面细胞凹陷不规则,相邻细胞壁厚,具密集的细疣。

Abstract: Paraffin sectioning technique and scanning electron microscopy methods were applied to observe six species of masses. The internal structure of stems,leaves and the stratum corneum surface ornamentation, warts growth and micro-hole were compared.The results indicated that the epidermal cells of Rhytidium rugosum(Hedw.) Kindb. have small verrucose on outer wall, while the tandem of the wall adjacent to the surface of the cuticle cell patterns long into parallel bundles; stem axis of the Abietinella abietina(hedw.) fleisch was not obvious, in the back of a rib-like thorns protruding warts, dorsal, ventral surfaces of the side wall warts, was covered like; the epidermal cells wall of Bartramia ithphylla Brid. uplift, holes was not sink, orifice was covered by the cuticle ornamentation; the back surface of leaf crude cell wall of Aulacomnium palustre(Hedw.) Schwagr. warts highlighted by the depression, cuticle ornamentation was banded, leaf faces big belly, and in many cell wall-like interface was open; the epidermal cells of back leave of Hylocommium splendens(Hedw.) B.S.G wart like thorns wide, dorsal, ventral warts rough high, the top of the cell wall with depression; Dorsal, ventral cells irregular depressions adjacent cell wall of Ceratodon purpureus(hedw.) Brid. was a small intensive wart.
