水稻第三叶片表面的扫描电镜观察

()
摘要:
用扫描电镜对普通野猪、籼稻和粳稻三叶期第三叶表面结构进行了观察研究。发现了三叶期第三叶片的硅化-木栓细胞带和气孔器乳突发育不完全的现象。气孔带乳突特征是粳稻小而密,普通野稻大而稀,籼稻居中。大瘤状乳突的形状,普通野稻为扁圆柱形,籼稻为长圆柱形,粳稻为椭圆球形,但农家粳稻品种与普通野稻相似。

The Observation on Surface of 3rd Leaf in Rice with Electronic-Scanning Microscope
Abstract:
The microstructure on surface of 3rd leaf in Oryza rufipogon, O. sativa (hsien or indica and keng or japonica)were studied with electronic-scanning microscope. The silica-phellem block and stomate tubercle on 3rd leaf are underdeveloped, the tubercle of stomate block is small and dense in japonica, big and sparse in O. rujipogon and intermidiate in indica. The large on leaf-back is the short cylinder in O.rufipogon and primeval japonica, the long cylinder in indica and circular in japonica.
Key words:  rice,3rd leaf,tubercle
