摘　　要：以洛氏鱥(Phoxinus lagowskii)肾组织为材料,采用腹腔注射植物血球凝集素(PHA)、秋水仙素和空气干燥法制备染色体标本,进行染色体组型分析。结果表明:洛氏鱥染色体为50条,核型公式为2n=50=24m+14sm+12t,臂数NF=88,未发现异型染色体、随体染色体和次缢痕。Karyotype of Phoxinus lagowskii was studied with chromosome samples prepared from kidney by injecting phytohaemagg lutinin（PHA） and colchicine and air-dried method. The results showed that there were 50 chromosomes in P. lagowskii, and karyotype formula of P. lagowskii was 2n = 50 = 24 m ＋ 14 sm ＋ 12t; NF = 88. There was no evidence of heterotypical chromosome, satellites or secondary constriction.
