摘要
以7种聚乙烯塑料核型为珠核,正常壳形与二壳隆起的畸形企鹅珍珠贝为手术贝,培育附壳珍珠。养殖6个月,结果表明:壳形正常的育珠贝成活率为73.3%～93.8%,成珠率55.0%～82.0%;畸形贝成活率为60%,成珠率53.3%。统计分析表明:珠核高度是影响育珠贝成活率和成珠率的主要因素,珠核越高,育珠贝成活率和成珠率越低。畸形贝与正常壳形贝成活率和成珠率存在极显著差异(P<0.01),畸形贝不宜用作手术贝。
During the blister pearl cultivating, pearl nucleus made from polyethylene plastics and surgical pearl oysters chosen from both normal and malformation in shape were used. After six months of culture , survival and pearl formation rate of oysters in normality shape was 73.3 % - 93.8 % and 55.0 % - 82.0 %, respectively. The survival rate and the percentage of pearl formation of the malformed was 60 % and 53.3 % respectively. The experiments indicated that the height of pearl nucleus had a significant influence on the survival and percentage of pearl formation of pearl producing shell. The higher pearl nucleus was, the lower survival rate and percentage of pearl formation of the oysters would be. There was highly significant（ P 〈 0.01 ） difference between the pearl producing shell of normality and malformation in shell shape in survival rate and percentage of pearl producing. Furthermore, the malformaed oysters should not be used for the production of blister pearl.
