摘要: <正>进一步对荚属的木绣球和雪球荚两个种的核型进行研究,结果表明它们的核型组成是不同的,木绣球2n=18=12m+4sm+2smsat,雪球荚2n=16=12m+4sm。但是结果亦表明按Stebbins的非对称核型分类它们有相同的非对称性核型2B型。因此这两个种亲缘上是相近的。

Abstract: A continuation of study was made on karyotypes two species of Viburnum L. The result confirmed that their constitution in karyotypes was different. The V. Macrocephlalum Fort. Var. Keteleeri  Nichals 2 n=18=12 m+4 sm+2 smsat and the V.Plicatum  Thunb 2 n=16=12 m+4 sm. But the result also showed that they were the same asymmetrical karyotypes 2B type according to Stebbins’ system of asymmetry karyotype. Therefore the two species were close in consanguinity.
