摘要/Abstract

摘要： 为了评价复合性状转基因棉花种植对土壤线虫群落结构的影响，分析了大田条件下分别种植3种复合性状转基因棉花sGK321、转Cry1Ac+Cry2Ab基因棉（双Bt抗虫棉）和转Cry1Ac+Epsps基因棉（抗虫抗除草剂棉）及常规棉石远321的土壤线虫数量、营养类群组成和生态指数。结果表明，与石远321相比，种植3种复合性状转基因棉的土壤线虫数量无显著差异。土壤中共鉴定出20科、36属土壤线虫，包括10属植物寄生线虫、10属食细菌线虫、5属食真菌线虫和11属杂食/捕食性线虫。其中食细菌线虫为优势营养类群，真头叶属（Eucephalobus）、螺旋属（Helicotylenchus）、板唇属（Chiloplacus）、绕线属(Plectus) 和原杆属（Protorhabditis）为优势属。3种复合性状转基因棉和石远321种植下土壤线虫群落Shannon多样性指数（H）、优势度指数（λ）、丰富度指数（SR）和成熟度指数（MI、PPI）均无显著差异，只有双Bt抗虫棉土壤线虫群落Pielou均匀度指数有显著差异。说明大田种植3种复合性状转基因棉对土壤线虫群落结构和种类组成的影响不显著。
