摘要:

为了完善有关裂叶苔科植物孢子、弹丝和油体的研究,为该科植物的分类提供详细的资料,利用光学显微镜和扫描电镜观察裂叶苔科(Lophoziaceae)11种植物的孢子、弹丝和油体的形态特征,其中有6种具备了孢子和弹丝的形态特征,9种具备了油体的形态特征。结果表明:①裂叶苔科的6种植物的孢子为球形、近球形和椭圆形;颜色为褐色、红褐色和黄褐色;直径在10~16 μm,属于小型孢子(MI);近极面向内凹,纹饰为疣状、棍棒状、刺状、颗粒状和短棒状。②弹丝均为紧密双螺旋状,两端圆钝,表面平滑或具稀的颗粒2种。③裂叶苔科的9种植物的油体形状为球形、椭圆形、球形或卵形,直径在3~10 μm。本研究对这11种植物的孢子、弹丝和油体进行了详细的描述并附图示,为裂叶苔科植物的系统分类、演化研究提供基础资料。

Abstract:

To improve the characteristics of the spore,elater and oil body of Lophoziaceae and to provide detailed information for classification,the morphology of 11 species of the Lophoziaceae was observed by scanning electron microscopy, 6 species provided for the morphological characteristics of spore and elater,and 9 species provided for oil body. The results showed that:①The spores of 6 species of Lophoziaceae were spherical, near spherical or elliptical with brown, reddish-brown or yellowish brown respectively. The spore size of them were from 10-16 μm belonging to MI type,and their faces near pole were usually concave. The ornamentation of the above spores were verrucose,clavate,spinate,granular or short baculite respectively. ②The elaters of 6 species of Lopholoziaceae were densely bispiral with obtuse both ends,and their cuticle were smooth or granulate.③The oil bodies of 9 species of Lophoziaceae were spherical,elliptical or oval,with the diameter between 3-10 μm. The detailed description and illustration on morphological evidence of spores,elaters and oil bodies of 11 species of Lophoziaceae might provide the elemental data for the systematic taxonomy and evolution of Lophoziaceae.

Key words: Lophoziaceae, spore, ornamentation, elater, oil body
