| 摘 要： | 试验采用了染色体压片法研究了热研11号黑籽雀稗Paspalum atratum cv.‘Reyan11’的染色体数目和核型。结果表明:热研11号黑籽雀稗的染色体数目2n=40,核型公式为2n=2x=40=32m+4sm+2st+2M。核型分类为"2A"型,比较对称。研究确定了热研11号黑籽雀稗染色体的数目,并分析了其核型,这为热研11号黑籽雀稗的起源演化及分子生物学提供了细胞学研究基础。

| Abstract: | The chromosome number and the karyotype of Paspalum atratum cv. Reyan 11 were investigated by the method of root tip squash. The result showed that the chromosome number of somatic cells was 2n=40,the karyotype formula was 2n=2x=40=32m + 4sm + 2st + 2M. The karyotype belonged to type 2A,and it was quite symmetrical. This confirmed the chromosome number of P. atratum cv. Reyan 11 and analyzed its karyotype,which would provide basis for the research of cytology in genesis evolution and molecular biology of P.... |
