摘    要:目的]探讨外源海藻糖对家蚕的生长和茧丝品质的影响。方法]通过对家蚕品种菁松×皓月进行添食试验,研究添加海藻糖对家蚕的生长和茧丝品质的影响。结果]添加海藻糖后家蚕上蔟更为整齐,茧丝纤度降低,而生存率、体重、4龄结茧率、普茧率、解舒率、粒茧丝长和解舒丝长都增加。综合评价结果表明,添加20 mmol/L海藻糖的家蚕成绩最优。结论]外源性海藻糖对提高家蚕生长和茧丝品质具有积极作用。

关 键 词:外源海藻糖  家蚕  生长  茧丝品质  综合评价

Abstract:Objective] The research aimed to discuss the effects of exogenous trehalose on the growth and silk quality of silkworm.Method] The feeding experiment was made on the silkworm variety Jingqing ×Haoyue to study the effects of adding trehalose on the growth and silk quality of silkworm.Result] After adding trehalose,the mounting time was shorter and the size of cocoon filament decreased,but the survival rate,body weight,the cocooning ratio of the fourth-instar larvae,percentage of common cocoon,reelability,per cocoon’s filament length and length of non-broken cocoon filament increased.The results of the comprehensive evaluation showed that the performance of silkworm with adding 20 mmol/L trehalose was the best.Conclusion] Exogenous trehalose was of positive significance for enhancing the growth and the silk quality of silkworm.
Keywords:Exogenous trehalose  Silkworm  Growth  Silk quality  Comprehensive evaluation
