摘要
以马氏珠母贝育种对照群体为实验材料,从群体中选择生长差异个体分别构成大规格与小规格子群体,测定两个子群体鳃、肝胰腺、闭壳肌、外套膜边缘膜与外套膜中央膜类胡萝卜素含量。结果表明:大规格与小规格子群体的鳃、肝胰腺、闭壳肌、外套膜边缘膜与外套膜中央膜的类胡萝卜素含量差异不显著(P>0.05),大规格子群体各组织的类胡萝卜素含量略大于小规格子群体。大与小规格子群体肝胰腺的类胡萝卜素含量显著高于其它4种组织(P<0.05)。子群体对类胡萝卜含量影响不显著(P>0.05),组织对类胡萝卜含量影响显著(P<0.05)。肝脏是马氏珠母贝类胡萝卜素转化及沉积的主要器官之一。
In this study, large-sized (LS) and small-sized (SS) groups of pearl oysterPinctada martensii were established based on the significant difference in growth traits from a control stock in our breeding program.Total carotenoid content (TCC) of LS and SS groups in soft tissues, including gill, hepatopancreas, adductor muscle, mantle edge and mantle centre, were not significant differences (P > 0.05) but with slightly higher in the LS group. TCC in hepatopancreas in both LS and SS groups were significantly higher than those in gill, adductor muscle, mantle edge and mantle centre. TCC are no significant difference between group (P > 0.05) but are significant difference among tissues (P< 0.05). These results suggest that the hepatopancreas is an important tissue in transformation and accumulation of carotenoids.
