| 摘 要： | 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. |
