Abstract

The population of Datura stramonium L. var. tatula Torr and Datura wrightii Regel was heterogenous in the numerical and structural composition of karyotypes. Datura wrightii Regel contained, as well as aneuploid sets, a 35% karyotype with a diploid set of chromosomes (2n = 24); there were no chromosomes with satellites and there were 1-2 microchromosomes in 29.6% of the metaphases. Datura stramonium L. var. tatula Torr included biotypes with a chromosome number of 21-25; in 88.5% of the metaphases there were chromosomes with satellites and 60% of the metaphases contained 1-3 microchromosomes. According to the content of the main alkaloids Datura stramonium L. var. tatula Torr can be considered a predominantly hyoscyamine type, Datura wrightii Regel also containing scopolamine.

摘要

曼陀罗（Datura stramonium L. var. tatula Torr）和曼陀罗（Datura wrightii Regel）种群在核型的数值和结构组成上存在异质性。曼陀罗（Datura wrightii Regel）除了存在非整倍体组外，还包含一个具有二倍体染色体组（2n = 24）的 35%核型；没有带卫星的染色体，在 29.6%的中期有 1-2 个微染色体。曼陀罗（Datura stramonium L. var. tatula Torr）包括染色体数为 21-25 的生物型；在 88.5%的中期有带卫星的染色体，60%的中期含有 1-3 个微染色体。根据主要生物碱的含量，曼陀罗（Datura stramonium L. var. tatula Torr）可以被认为是主要的莨菪碱型，曼陀罗（Datura wrightii Regel）也含有东莨菪碱。
