Damage of cadmium and lead to DNA chain and the effects on cocoon quality were studied in silkworm under exposure of different cadmium and lead concentrations.
利用4龄起家蚕,添食不同浓度的Pb2+、Cd2+重金属离子,研究其对家蚕茧质和DNA损伤的影响。
uantitative analyses are made on such factors as reelable cocoon ratio, cocoon quality,cocoon cooking/silk reeling technology and management that affect silk yielding of fresh cocoons,with corresponding measures presented to improve reelable cocoon ratio,cocoon quality and cocoon cooking/silk reeling levels.
本文就上车率、茧质、煮茧缫丝技术与管理三因素对鲜茧出丝率的影响作了定量分析，并提出了提高上车率、改善茧质和提高煮缫水平的相应措施。
The results showed that the numbers of enzyme bands and the enzyme activity swelled in region A,hatching rate declined with increase of the dose of N +,newly hatched silkworm setae dispersion rate enhanced a little and difference of development in individual swell but cocoon quality retain.
家蚕卵期N+ 注入后 ,当代蛹期进行血液酯酶同工酶电泳 ,发现A区酶带数和活性比对照增强 ,经N+ 注入后的孵化率随剂量增加而下降 ,孵化出的蚁蚕疏毛率比对照略有提高 ,个体间发育开差增大 ,茧质并未下降 ,出现个别环节畸变蚕。
