尽管转基因玉米被广泛种植，并有大量关于其农业环境影响的科学报告，但转基因玉米的风险和益处仍在争论中，对安全性的担忧依然存在。这项荟萃分析旨在通过分析同行评议的文献(1996年至2016年)有关产量、籽粒品质、非目标生物(NTOS)、目标生物(TOS)和土壤生物量分解的文献，增加对转基因玉米农艺、环境和毒理学特性的了解。结果表明，转基因玉米比其近等基因系表现更好：在较低浓度的真菌毒素(−28.8%)、伏马菌素(−30.6%)和硫杆菌毒素(−36.5%)的作用下，籽粒产量提高5.6~24.5%。所分析的nto不受转基因玉米的影响，但以鳞翅目活跃的Bt玉米的靶标--欧洲玉米螟寄生蜂为代表的茧蜂除外。秸秆和叶片中的木质素含量等生物地球化学循环参数没有变化，而生物量分解在GE玉米中更高。这一结果支持转基因玉米的种植，这主要是由于提高了籽粒品质和减少了人类对真菌毒素的暴露。此外，还证实了靶标寄生蜂的减少以及对其他NTO缺乏一致的影响。
Despite the extensive cultivation of genetically engineered (GE) maize and considerable number of scientific reports on its agro-environmental impact, the risks and benefits of GE maize are still being debated and concerns about safety remain. This meta-analysis aimed at increasing knowledge on agronomic, environmental and toxicological traits of GE maize by analyzing the peer-reviewed literature (from 1996 to 2016) on yield, grain quality, non-target organisms (NTOs), target organisms (TOs) and soil biomass decomposition. Results provided strong evidence that GE maize performed better than its near isogenic line: grain yield was 5.6 to 24.5% higher with lower concentrations of mycotoxins (−28.8%), fumonisin (−30.6%) and thricotecens (−36.5%). The NTOs analyzed were not affected by GE maize, except for Braconidae, represented by a parasitoid of European corn borer, the target of Lepidoptera active Bt maize. Biogeochemical cycle parameters such as lignin content in stalks and leaves did not vary, whereas biomass decomposition was higher in GE maize. The results support the cultivation of GE maize, mainly due to enhanced grain quality and reduction of human exposure to mycotoxins. Furthermore, the reduction of the parasitoid of the target and the lack of consistent effects on other NTOs are confirmed.
