利用根尖压片法对悬铃花进行核型分析。结果表明：悬铃花体细胞的染色体数为2n＝28,相对长度系数组成为：2L＋10M2＋8M1＋6S，核型不对称系数为：59.95%；其核型公式为：20m＋8sm，属2B 核型。为今后锦葵科悬铃花属植物核型分析研究提供一定的借鉴和依据。

The karyotype analysis of Malvaviscus arboreus Cav. was studied by using root-tip squashing method. The results showed that the number of chromosomes in somatic cells of Malvaviscus arboreus Cav. was 2n=2x=28, the relative length of chromosome was 2n=2x=28=2L+10M2+8M1+6S, and the karyotype asymmetry index was 0.5995. This species belongs to the 2B karyotypic symmetry class with a 20m+8sm karyotype formula. This study will provide the basis and reference for future work on karyotype analysis in genus of Malvaviscus arboreus Cav..
