Artificial induction of gynogenetic diploids by suppression of the first cleavage in Atrina pectinata
摘要
Abstract
The induction of gynogenesis diploids by suppression of the first cleavage in Atrina pectinata was attempted using the treatment of 6-dimethylaminopurine(60 rag/L; 6-DMAP). The results showed that the treatment of zygotes with 6-DMAP at 60 rain postinsemination for 15 min at water temperature of 24℃ produced more expected D-shaped larvae, and the rate of D-shaped larvae and level of diploids were 14. 7% and 22.7%, respectively. According to cytological observations, 6-DMAP disrupted the spindle at mi-tosis and inhibited chromosome movement, resulting in the formation of one diploid female nucleus. Cyto-logical evidence of the induction of gynogenetic diploids in A. Pectinata was demonstrated.关键词
