Abstract

In the present investigation, Strychnos nux vomica L. and Strychnos wallichiana Steud. ex A. DC. have been selected for karyotypic investigation to strengthen genetic relationships. Chromosome number recorded in S.nux vomica is 2n=32 while in S. wallichianais 2n=40. In both species A-type, B-type and C-type chromosomes were observed with 28 metacentric chromosomes and 4 sub-metacentric in S. nux vomica and 38 metacentric and 2 sub-metacentric chromosomes in S. wallichiana. The total form per cent (T.F %), Dispersion Index (DI), Asymmetry index (AI) depict the symmetric karyotype of chromosomes which represents their primitive level in the family.

马钱子属两种植物的核形态学研究，具有民族药理学意义

在本研究中，马钱子和马钱子。不包括A.DC。已被选择用于核型研究以加强遗传关系。马钱子的染色体数目为2n=32，华氏马钱子为2n=40。在两个种的A型、B型和C型染色体中，马钱子有28条中心染色体和4条亚中心染色体，华氏猪钱子有38条中心和2条亚中中心染色体。总形态百分比（T.F%）、分散指数（DI）、不对称指数（AI）描述了染色体的对称核型，代表了它们在家族中的原始水平。
