摘要
以马氏珠母贝快速生长选系F3为材料,以常规技术插核操作并进行海区养殖,育珠期结束,测量育珠母贝的壳长、壳高、壳宽、总质量与壳质量共5个生长性状指标,以及商品珍珠质量与珍珠层厚度,分析育珠贝生长性状指标与珍珠层厚度及珍珠质量的相关性。结果表明:马氏珠母贝的生长性状与珍珠层厚度及珍珠质量均存在极显著相关性(p值<0.01);壳长、壳高、壳宽、总质量、壳质量与珍珠层厚度的相关系数分别为0.481、0.412、0.418、0.457、0.456;壳长、壳高、壳宽、总质量、壳质量与珍珠质量的相关系数分别为0.467、0.468、0.380、0.556、0.644。通过改良马氏珠母贝养殖群体的生长性状能够有效提高珍珠的质量。
Fast breeding F3 of Pinctada martensii was chosen as material,and bred in sea area after pearl-nucleus-inserting operation.After the pearl breeding,shell length,shell height,shell width,total weight and shell weight of nacre were measured;thickness and weight of pearl were also measured after anatomy of nacre.Pearson correlation of the phenotypic traits and the pearl thickness and weight were analyzed by SPSS11.0.It showed that the morphological trains and thickness and weight of pearl were highly significant correlated.The correlation coefficient of shell long,shell height,shell width,total weight,shell weight and pearl thickness were： 0.107,0.212,0.144,0.254,0.256.The correlation coefficient of shell long,shell height,shell width,total weight,shell weight and pearl weight were 0.167,0.468,0.38,0.556,0.644.The result indicated that the pearl quality could be enhanced by improved morphological trains of Pinctada martensii breeding groups.
