| 摘 要： | 采用体内注射PHA和秋水仙素的方法,利用成体的鳃组织,对毛蚶(Scapharca subcrenata)、长竹蛏(Solen strictus)和菲律宾蛤仔(Ruditapes philippinarus)的核型进行了研究.结果表明毛蚶的2倍体数目为2n=38,核型为18m+16sm+2st+2t,NF=72.长竹蛏的2倍体数目为2n=38,核型为30m+6sm+2t,NF=74.菲律宾蛤仔的2倍体数目为2n=38,核型为28m+10sm,NF=76.

| Abstract: | The karyotypes of three species of marine molluscs (Bivalva),Scupharcu subcrenata,Solen conriitus and Ruditupes philippinarus were analyzed by means of injection of PHA and colchicine.The chromo-somes were prepared from the gill cells.The diploid number of three bivalve molluscs are the same as 2n=38.The karyotype of Scupharca cubcrenata is 18m+16sm+2st+2t,NF=72.The length of the metaphase chromosomes in diploid (CL)is from 1.93μm to 3.16μm, and their total length (TCL) is 105.9μm.The karyotype of.Solen contric-tus is 30m+6sm+2t,NF=74.CL:2.73-3.61μm,TCL=130.02μm.The karyotype of Rutttapes bhilibbinarus is 28m+10sm,NF=76.CL:2.71-1.02μm, TCL=134.02μm. |
