农民们种植经遗传操作的抗阿特拉津的作物可能不会高产。明尼苏达州莫里斯的美国农业部农业研究局中北部地区土壤保持研究室的农学家 F.Forcella 进行了一组试验。在没有杂草和除草剂的条件下,将与抗除草剂的野芥杂交得到的油菜品种和对除草剂敏感的油菜种种在一起。结果表明,对除草剂敏感的油菜比抗除草剂品种每英亩多产880磅;在另一试验中,让敏感油菜与杂草野燕麦群体竞争,而抗性油菜 Farmers who grow genetically-engineered anti-atrazine may not be productive. F. Forcella, a researcher at the Soil Conservation Laboratory in the North Central Region of the Agricultural Research Service of the U.S. Department of Agriculture in Morris, Minn., Conducted a series of experiments. In the absence of weeds and herbicides, the rapeseed cultivars that crossed with the herbicide-resistant mustard and the herbicide-sensitive rape were combined. The results showed that the herbicide-sensitive rape grew 880 pounds more per acre than the herbicide-resistant varieties; in another trial, the susceptible rape competed with the weed wild oat populations while the resistant rape
