内容記述 | The induction of gynogenetic tetraploids by the suppression of the meiotic division in the Pacific oyster Crassostrea gigas was attempted in three trials using the treatments of cytochalasin B (0.5μg/mL; CB). The effects of various durations of CB treatment on tetraploid induction frequency were examined. Haploid gynogenesis was induced by sperm which were UV-irradiated for 60s at an intensity of 72erg/mm^2/s. CB treatment was effective in inhibiting meiosis, and the optimum time for the suppression of both the 1st and 2nd polar bodies was from 10 to 45min postinsemination, yielding 51.4% gynogenetic tetraploids. The results of this study suggest the possibility of producing gynogenetic tetraploid Pacific oysters. | |||||||||
