静水压法诱导虹鳟三倍体试验OA

Using the diploid female of rainbow trout(Oncorhynchus mykiss)as the mother and the diploid pseud-omale as the father,the hydrostatic pressure method was used to induce triploid of rainbow trout,and the appropri-ate conditions for inducing triploid of rainbow trout by hydrostatic pressure method were initially explored.The re-sults showed that the triploid induction rate of rainbow trout was affected by the initial time,pressure and duration of treatment.The optimum conditions for inducing triploid of rainbow trout by hydrostatic pressure were the initial treatment time of 30 min～40 min,hydrostatic pressure of 65 MPa～70 MPa,and duration of 4 min～6 min.
