Controversy continues to exist regarding whether the transgene for glyphosate resistance (GR) and/or glyphosate applied to GR crops adversely affect plant mineral content. Field studies were conducted in 2013 and 2014 in Stoneville, MS and Urbana, IL to examine this issue in maize. At each location, the experiment was conducted in fields with no history of glyphosate application and fields with several years of glyphosate use preceding the study. Neither glyphosate nor the GR transgene affected yield or mineral content of leaves or seed, except for occasional (<5%) significant effects that were inconsistent across minerals, treatments, and environments. Glyphosate and AMPA (aminomethylphosphonic acid), a main degradation product of glyphosate, were found in leaves from treated plants, but little or no glyphosate and no AMPA was found in maize seeds. These results show that the GR transgene and glyphosate application, whether used for a single year or several years, have no deleterious effect on mineral nutrition or yield of GR maize.

抗草甘膦技术对玉米矿物质含量和产量影响极小或没有影响

关于草甘膦抗性 (GR) 转基因和/或应用于 GR 作物的草甘膦是否会对植物矿物质含量产生不利影响，仍然存在争议。 2013 年和 2014 年在密西西比州斯通维尔和伊利诺伊州厄巴纳进行了实地研究，以研究玉米中的这一问题。在每个地点，实验都是在没有草甘膦施用历史的田地和在研究之前使用草甘膦多年的田地中进行的。草甘膦和 GR 转基因都不影响叶子或种子的产量或矿物质含量，除了偶尔（<5%）的显着影响，这些影响在矿物质、处理和环境之间不一致。在处理过的植物的叶子中发现了草甘膦和 AMPA（氨甲基膦酸）（草甘膦的主要降解产物），但在玉米种子中发现了很少或没有草甘膦和 AMPA。这些结果表明，GR转基因和草甘膦施用，无论是一年还是几年，对GR玉米的矿质营养或产量都没有有害影响。
