Abstract:

The large-tubercles, papicles of phellem cell and papicles of stomate on leaves-back in 9 species of Oryza L. were studied with scanning-electric microscope. The 4 groups of 9 species were classified with presence or non-presence of large-tubercles, papicles of stomate and papicles of phellem cell. They are qualitative difference between groups and quantitative difference in groups.

Key words: leaf back, Oryza, submicrostructure

摘要： 用扫描电镜对稻属植物9个种叶背的大瘤状乳突、本栓细胞乳突和气孔器乳突的亚显微结构作了比较观察研究。依有无木栓细胞乳突、有无气孔器乳突和有无大瘤状乳突而将其分为四群。群间有质的不同，群内亚种间和品种间只有数量之别。表明用亚显微形态结构作为分类性状是有意义的。
