| 摘 要： | 观察分析了5种报春花属（Primula）植物的染色体数及核型。体细胞有丝分裂中期染色体数及核型分别为：小报春（P. forbesii）,2n=2x=18m；偏花报春（P. secundiflora Franch），2n=2x=20m+2sm；藏报春（P. sinensis），2n=2x=20m+2M；胭脂花（P. maximowiczii），2n=2x=22m；齿叶灯台报春（P. serratifolia），2n=2x=22m。其中小报春、藏报春、胭脂花和齿叶灯台报春的核型为首次报道。

| Abstract: | In this paper, karyomorphologically studies were carried out on five species of Primula. The results were as follows. The number and karyotypes of metaphase chromosomes were formulated to be 2n=2x =18m for P. forbesii, 2n=2x=20m 2sm for P. secundiflora Franch, 2n=2x=20m 2M for P. sinensis, 2n=2x=22m for P. maximowiczii,2n=2x=22m for P. serratifolia. The karyotypes were all of 1A type ex- cept P. sinensis which the karyotype was 1 B type.The karyomorphology of four species, P.forbesii,P. sinensis, P. maximowiczii, P. serratifolia were reported for the first time. |
