摘要: 抗除草2剂2转基因植物(herbicide r2es2istant ically modified p lant (HR GM P) ) 已在全世界广为种植。由
于种内、种间抗性基因的转移、互渗和某些转基因植物类型自身具有较强的杂草性, 转基因2植物的田间试验和商业
化种植都存在着产生新的杂草类型, 甚至超级杂草的风险。即形成: (1) 逸生型杂草, (2) 衰退型杂草, (3) 超级杂草,
对生物多样性构成威胁。

Abstract: T he herbicide resistan t ically modified p lan ts (HR GM P) has been w idely cu ltivated in the

relatives, HR GM P p lan ting and cu ltivating w ill take risk s of the vo lun teer w eeds, and lead to po ten tial en
