摘要
本试验地对3品种的桑蚕转青卵经不冷藏、冷藏3d、6d、9d、11d、13d、17d、20d8种处理进行了蚕卵磷脂的提取和定量及一日孵化率调查 ,结果表明 :3品种蚕卵的一日孵化率经3d、6d冷藏后有一定提高 ,冷藏13d后一日孵化率仍达92.33% ,符合国家行业标准 ;3品种转青卵膦脂含量冷藏区较不冷藏区有不同程度下降 ,3d冷藏区3品种下降的幅度在23.34% -14.41 %之间 ,各冷藏区之间无明显差异 ;
Extraction and determination of phospholipids and hatchability of blue-stage-eggs from three silkworm varieties were carried out in 8 types of cold-storage treatments. Results showed that hatchability increased differently among three varieties by cold-stored for six days. However, cold-stored for more than six days, hatchability decreased slightly. Cold-stored for 13 days, hatchability could maintain 92.33%, which still met the requirement of national standard. Quantity of phospholipids in bluish-silkworm-eggs of three varieties decreased differently after cold-storage treatments, and its decreasing range after cold-storage treatment for three days was withine 23.34% to 14.41%. There was no significant difference among all types of cold-storage treatments, and no significant relationship between the quantity of phospholipids and one-day-hatchability of bluish-silkworm-egg.
