| 摘 要： | 本文对分布于陕西省的3种绞股蓝植物进行了染色体观察。其结果：绞股蓝染色体数为2n=2x=22，长梗绞股蓝为2n=2x=22，心籽绞股蓝为2n=6x=66。后两种为本文首次报道。 这些观察结果为我国绞股蓝属植物的分类和推广利用提供了细胞学依据。

| Abstract: | The chromosome numbers of three species of the Genus Gynostemma from Shanxi Province are reported as follows: 1.G. pentaphyllum is diploid 2n =2x=22; 2. G. longipes is diploid 2n=2x=22; 3. G..cardiospermum is hexaploid 2n=6x= 66. The last two species are endemic species of China, their chromosome numbers are reported for the first time. These results provide the scientific basis for classi-fying and utilizing the plants of the Genus Gynostemma. |
