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.serratfolia),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。
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 except 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.
