| 中文摘要: |
| 为了探究鱼类胚胎发育过程中主要营养物质消耗利用的规律,采用生物化学方法测定了瓯江彩鲤(Cyprinus carpio var.color)胚胎发育过程中7个发育期的主要生化成分。结果表明,(1)瓯江彩鲤受精卵期水分含量达70%以上,随着发育的进行,胚胎的含水量呈逐渐上升的趋势;(2)胚胎发育过程中脂质的利用主要集中在胚胎发育的晚期,总脂中磷脂的含量低于中性脂,且磷脂含量随胚胎发育进程明显下降,而中性脂含量趋于稳定;(3)胚胎发育过程中粗蛋白的含量明显增加,可溶性蛋白的含量逐渐降低;(4)胚胎碳水化合物的含量较低,其中胚胎发育早期含量最低,至神经胚期含量又出现回升。 |
| 英文摘要: |
| Changes in biochemical compositions during embryonic development were studied in Cyprinus carpio var.color by biochemical methods. The water content of fertilized eggs accounted for more than 70% and increased during the incubation period. Lipid utilization mainly occurred in the late embryonic development. The content of phospholipids was higher than that of neutral lipids and decreased with embryonic development, while the neutral lipids nearly remained constant. During embryonic development the total protein content increased significantly, contrary to the change of soluble protein. The carbohydrate content in embryos of C.c.var.color was very low, and a significant decrease was observed during embryogenesis, however, the carbohydrate content was increased close to the time of hatching. |
