| 摘 要： | [目的]研究家蚕的耐氟机理。[方法]以耐氟家蚕品种T6和氟敏感家蚕品种733新为供试品种,采用酸浸提法测定蚕沙、饲料、全蚕体的氟含量。[结果]添氟和不添氟饲料的实测含氟量分别为413.3和56.5mg/kg。在添氟14d后,耐氟组家蚕品种T6个体粗大仍然健康;氟敏感家蚕品种733新个体很小,取食量显著下降,蚕沙量比对照组明显减少,表现出明显的氟中毒症状。添氟初期和表现症状的后期,氟敏感家蚕的蚕沙氟含量有所波动。从第8天开始,耐氟家蚕品种的蚕沙氟含量显著下降。氟敏感品种733新的排泄能力高于耐氟品种T6。耐氟和氟敏感家蚕的蚕沙平均氟含量与全蚕体内氟含量的和相近。[结论]家蚕体内可能有某种（类）氟过氧化物酶,使游离氟失去毒害作用。

| Abstract: | [Objective] The aim was to study the fluoride-tolerant mechanism of Bombyx mori.[Method] With fluoride-tolerant B.mori strain T6 and fluoride-sensitive B.mori strain 733Xin as tested strains,the fluoride contents in silkworm feces,feed and whole silkworm body were determined by using acid extraction.[Result] The determined fluoride contents in feeds with and without fluoride addition were 413.3 and 56.5 mg/kg resp.After 14 d since fluoride addition,the individuals of B.mori strain T6 were still strong and h... |
