雪松针叶树脂道的解剖学研究
0
()
摘要:
裸子植物的叶在结构上比被子植物的叶变化较少,而且不受环境的影响,具有一定的分类学价值.通过常规切片和整体透明离析处理的方法对雪松(Cedrus deodara)针叶树脂道进行全面的解剖学研究,描述了雪松针叶树脂道的数目和位置、树脂道细胞的结构,对树脂道进行整体离析观察.本试验整体离析观察结果可为横切面上观察到树脂道的数目、位置提供补充,同时也为"裸子植物叶中树脂道一直被用为鉴别特征"提供佐证.

Anatomical research on resin canal in leaves of Cedrus deodara
()
Abstract:
Leave structure of gymnosperm is less changable than that of angiosperm,and thus it is valuable in classification.Anatomical experiment on slice,eduction and transparency of leaves of Cedrus deodara were conducted to study the number of resin canal,cell structure and the whole eduction observation.The results may supply some complements and prove the conclusion-"resin canal of gymnosperm was always an identified character".
Key words:  Cedrus deodara,resin canal in leaves,anatomy
