摘要
观察了云南省 8种甘蔗属及近缘属植物叶片下表皮的解剖结构 ,结果表明 ,肋区中刺细胞的有无、行数及形状 ,硅细胞及栓细胞的排列方式 ,表皮上附属物的类型 ,气孔的行数及副卫细胞的形状等在不同种之间是不同的 ,这些解剖特征可作为外部器官形态分类的补充 。
By observing anatomic structure of leaf hypodermis of 8 species from Saccharum and its related genera.It was shown that the existence or non existence of thorny cell,the lines and shapes of thorny cell,the arrangement of silica cells and cork cells ,the line numbers of stomatas and the shapes of subsidiary cells were different among spesies.The characteristics can be used as classification characteristics.They also are helpful for selection of resource species in sugarcane breeding.
