罂粟属三种植物的核型研究

Studies On The Karyotypes of Three Species Papaver

研究了罂粟属３种植物的染色体核型。罂粟（ＰａｐａｖｅｒｓｏｍｎｉｆｅｒｕｍＬ）的核型公式为Ｋ（２ｎ）＝２ｘ＝２２＝１８ｓｍ＋４ｓｔ，虞美人（Ｐａｐａｖｅｒｒｈｏｅａｓ）的核型公式为Ｋ（ｎ）＝１ｘ＝７ｍ，伪东方罂粟（Ｐａｐａｒｐｓｅｕｄｏ－ｏｒｉｅｎｔａｌｅ）的核型公式为Ｋ（２ｎ）＝６ｘ＝４２＝６ｍ＋３０ｓｍ＋６ｓｔ。虞美人的核型类型属于１Ａ型，罂粟、伪东方罂粟均属于３Ａ型。

This paper deals with the choromosome karyotypes of three kinds of plants in Papaver.The formula of Papaver somniferun L isk(2n)=2x=22=18sm+4st;the formula of Papaver rhoeas isk(n)=x=7m;the formula of Papaver pseudoori entale isk(2n)=6x=42=6m+30sm+6st.The karyotype of Papaver rhoeas belongs to 1A type, while those of Papaver Somniferm L and Papaver pseudo orientale beli ng to 3A type.
