摘　　要：本研究通过对5龄桑蚕(Bombyxmori)后部丝腺重量及其组织内氨基酸激活酶蛋白含量的跟踪测定 ,阐明了5龄桑蚕后部丝腺蛋白质生物合成规律。结果表明 ,桑蚕在5龄期后部丝腺氨基酸激活酶的含量变化与后部丝腺的重量变化基本同步 ,均随日龄呈“S”形曲线走向。后部丝腺重量及氨基酸激活酶蛋白含量变化的“S”形曲线可用逻辑斯蒂克曲线进行描述。Through the study on the weight of posterior division of silk-gland and its amino acid activator enzyme protein in5th inˉstar silkworm larvae,the posterior division of silk-gland's protein dynamic biosynthesis rules in5th instar silkworm larvae was deterˉmined.The result showed that the weight curve of posterior division of silk-gland and its amino acid activator enzyme protein were all'S'shape and could be described with Logistic model.
