摘要: 采用常规制片方法对4 种草本花卉的染色体数目、核型等进行了研究。结果分别为石竹(Diranthus chinensis)染色体数2n=14,核型公式为K(2n)=14=12 m+2 sm,其核型为“1A”;裂叶花葵(Lavatera trimestris Linn.)染色体数2n=14,核型公式为K(2n)=14=6 m+8 sm,核型为“2A”;观赏椒(Capsicum frutescans)染色体数2n=24,核型公式K(2n)=24=24 m,核型为“1B”;凤仙(Impatiens balsamina)染色体数2n=14,核型公式为K(2n)=2x=14=10 m+4 sm,核型为“1B”。此4 种植物的染色体核型均为首次报道,可为花卉的良种选育和分类提供必不可少的依据。

Abstract: In this paper, conven-tional pressed slice method was used to study chromosome number and karyotype of four herbaceous flowers. The results showed that Diranthus chinensis:chromosome number 2n=14, karyotype formula K(2n)=14=12 m+2 sm, belonging to “1A” type; Lavatera trimestris Linn :chromosome number 2n=14, karyotype formula K(2n)=14=6 m+8 sm, belonging to “2A” type; Capsicum frutescans :chromosome number 2n=24, karyotype formula K(2n)=24=24 m, belonging to “1B” type; Impatiens balsamina :chromosome number 2n=14, karyotype formula K(2n)=2x=14=10 m+4 sm, belonging to “1B” type. This is the first report of karyotype of these four flowers, and may help breeding and classification of flowers.
