摘要:

为了测定几种不同倍性的黑麦草核DNA含量,利用流式细胞术(Flow Cytometry,FCM)检测黑麦草的染色体倍性,并通过传统的染色体制片的方法对其结果进行验证。结果表明不同品种间细胞核DNA含量差异显著,且随着倍性水平的增加,细胞核DNA相对含量随之成倍增加。流式细胞术检测结果与染色体制片检测结果一致。利用流式细胞仪测定黑麦草核DNA含量,具有样品制备简单,测量快速,精度高等优点,是进行倍性鉴定的理想方法。

Abstract:

In order to determine DNA content of nuclear DNA of Ryegrass cultivars, the chromosome was measured by Flow Cytometry. At the same time, it determinated the DNA content and pliody of Ryegrass by the traditional method of chromosome. The result showed that, with the increase of ploidy level, the relative content of nuclear DNA presented doubling. The two detection methods were consistent. However, the method which used nuclear DNA content by Flow Cytometry was simple, rapid and high precision.
