摘要: 对白头翁进行了核型分析发现,按Levan等(1964) 标准,核型公式为2n=16=10m+2sm+4st,为2A 核型按照(Stebbin)方法分为。白头翁染色体数目、核型和有丝分裂各时期的特征均为首次报道。

关键词: 白头翁, 核型, 有丝分裂, 细胞学特征

Abstract: Karyotype of pasqueflower (Pulsatilla chinensis (Bge.)Regel.) was formulated as 2n=16=10m+2sm+ 4st,belonging to Stebbin’s (1971) 2A type. The karyotype,chromosome number and characteristics in different phases of mitosis in pasqueflower were reported firstly in the world.

Key words: pasqueflower, karyotype, mitosis, cytological characteristics
