高寒鲤染色体核型分析

KARYOTYPIC ANALYSIS OF FRIGID CARP

采用植物血球凝集素（ＰＨＡ）体内注射，肾组织细胞短期培养，常规空气干燥法制备了高寒鲤染色体，核型分析结果是：高寒鲤染色体的核型公式为２ｎ＝１００＝２８ｍ＋２８ｓｍ＋４４ｓｔｔ，染色体臂数ＮＦ＝１５６。

With PHA culture in vivo,Frigid carp metaphase specimens wer prepared from short -term in vitro culture of kiney cells ,with air -drying technique .The result:the karyotype is 2n=100=28m+28sm+44st.t,NF=156
