| 摘 要： | 采用改良的Giemsa C带技术，分析了小麦族披碱草属、鹅观草属和猬草属模式种的染色体C带带型。Elymus sibiricus、Roegneria caucasica和Hysrix patula的染色体在Giemsa C带带型上存在明显的差异，显示了这3个属模式种的物种特异性。3个模式种的Giemsa C带核型表明，C带带纹主要分布在染色体的末端和着丝粒附近，而中间带相对较少。对E.sibiricus、R.caucasica和H.patula的St、H、Y染色体组C带带型与其它物种的St、H、Y染色体组C带带型的差异进行了讨论。

| Abstract: | The Giemsa C banding analyses of type species of Elymus L., Roegneria C. Koch and Hystrix Moench in Triticeae were carried out by using an improved C banding procedure. The Giemsa C banding patterns among E sibiricus?R caucasica and H patula were distinct,indicating the interspecific differentiation of the three type species. Most of the Giemsa C bands of the three type species distributed on chromosome telomere and centromere, with fewer intercalary bands. The C banding diferences of St, H or Y genome in E sibiricus,R caucasica and H patula between other species were discussed. |
