Abstract

The karyotypes (chromosome sets) of Trollius austrosibiricus, T. kytmanovii, and T. riederianus have been investigated for the first time. The karyotype formula has been obtained as 2n = 2x =16 = 2m + 2m/sm + 12sm for Trollius austrosibiricus and T. riederianus, and 2n = 2x =16 = 4m + 12sm for T. kytmanovii. A comparative analysis of the chromosome sets was conducted for these three species and the previously studied Trollius altaicus, T. asiaticus, T. ledebourii, and T. lilacinus (Hegemone lilacina) for several karyological parameters. The average absolute nuclear DNA content (2?-value) was originally determined for Trollius austrosibiricus, T. kytmanovii, T. ledebourii, and T. riederianus by flow cytometry.

亚洲-俄罗斯部分Trollius L.物种（毛茛科）的细胞遗传学特征

首次研究了澳洲Trollius austrosibiricus、T.kytmanovii和T.riederianus的核型（染色体组）。研究结果表明：澳洲金莲和里氏金莲的核型公式分别为2n=2x=16=2m+2m/sm+12sm和2n=2x=16=4m+12sm。对这三个物种的染色体组与先前研究的祭坛Trollius altaicus、亚洲T.asiaticus、莱氏T.ledebourii和紫丁香T.leculinus（Hegemone leculina）的几个核型参数进行了比较分析。最初通过流式细胞术测定了澳洲Trollius austrosibiricus、T.kytmanovii、T.ledebourii和T.riederianus的平均绝对核DNA含量（2？-值）。
