摘要: 为了解转Bt基因抗虫水稻对稻田浮游动物群落的安全性,本文以转Cry1Ab/Ac基因水稻“华恢1号”(HH1)为试验材料,以其非转基因亲本水稻“明恢63”(MH63)为对照,以浮游动物为指示生物,通过湖南湘潭基地连续3年的大田实验,研究了转Cry1Ab/Ac基因水稻对稻田浮游动物群落物种多样性的影响。结果表明:HH1与MH63两稻田生境浮游动物群落相似性高于0.70,优势种组成相似性高于0.89;浮游动物群落结构各参数的时间动态与总体分析均无显著差异;转Cry1Ab/Ac基因抗虫水稻HH1对稻田浮游动物群落物种多样性无不良影响。

Abstract: To understand the safety of transgenic Bt rice on zooplankton community in paddy fields, a safety evaluation experiment was conducted in 3 consecutive years in Xiangtan, Hunan Province, by using the transgenic Cry1Ab/Ac rice ‘Huahui No. 1’ (HH1 for short) as Bt rice material and the nontransgenic parent rice ‘Minghui63’ (MH63 for short) as control. The zooplankton community in paddy fields was used as bioindicator. The results showed that the similarity coefficients of all species composition and the dominant species of zooplankton community in HH1 and MH63 paddy fields were higher than 0.70 and 0.89, respectively. By comprehensive and temporal dynamic analyses, the parameters of zooplankton community in HH1 paddy fields in 2012, 2013 and 2014 displayed almost equal values and similar trends compared with those in MH63 paddy fields. These results suggested that transgenic Cry1Ab/Ac rice had no obvious adverse effect on zooplankton community in paddy fields.
