摘要: 本文采用染色体c带核型和银染核仁组成区定位分析方法对我国分布的伪稻蝗属(Pseudoxya)、稻蝗属(Oxya)和卵翅蝗属(Caryanda)进行了细胞学水平的系统分类研究。 结果表明,作为近缘属,此三属在常规核型和c带标志性带纹分布方面显示出一些共同特点, 表明其相互近缘的共性,然而在c带带纹分布型式及核仁组成区定位方面各有其特点,差异明显,这又是其属间相互独立的个性所在。由此,本文探讨了此三属之间细胞水平的分类学关系及该技术在细胞学分类学研究中的应用意义。

Abstract: This paper deals with the cytotaxonomy of genera Pseutdoxya, Oxyaand Caryands studied by C-banding and Ag-banding methods. The results show that these three genera have some common feature in the C-band distribution and conventional karyotype, indicating their close relationship. However, there are still some differences among the three genera in C-band distribution and NOR localization, showing their specialied aspects, the cytotaxonomic relationship among them and the taxonomic significance of chromosomal banding methods are discussed.

Key words: Pseudoxya, Oxya, Caryanda, chromosomal banding, cytotaxonomy
