摘要
对疣小金发藓、狭边大叶藓、密集匐灯藓、金发藓、黄色真藓、网孔凤尾藓和宽叶短月藓7种藓类植物茎的基部、中部和上部进行分段横切观察,结果表明:7种藓类植物茎基部的形状接近圆形,茎上部的形状各有特点,由茎基部到茎顶端的形状差异是逐步变化的,这与假根的存在和叶在茎上的着生位置有关。
The base part,the middle part and the upper part of the stem of seven mosses,Pogonatum urnigerum P.Beauv,Rhodobryum ontariense Kindb.,Plagiomnium confertidens T.Kop.,Polytrichum commune Hedw.,Bryum pallescens Schleich,Fissidens areolatus Griff.and Brachymeninm capitulatum Kindb.were analyzed by means of transection.The results showed that the transected shapes were close to the circular of the stem base part,the characteristics were different of the upper part.Different shapes were gradually changing from the stem base part to the upper part,which were related with the rhizoid and the positions of the leaves in the stem.
