Evaluating the impacts of genetically modified crops on biodiversity is a necessary step before their release to the field and obtaining environmental safety certificates. To assess the ecological safety of herbicide-resistant soybean ZUTS-33, we compared arthropod diversity, diseases occurrence, nodule number, and weed diversity through spraying herbicide or water on ZUTS-33, and its parental control receptor HC-3 and main cultivar soybean ZH-13 in a field experiment. The results showed that there was no significant difference of arthropod diversity (number of insects per 100 plants, Shannon index, Simpson index and Pielou index), diseases incidence rates and disease index, nodules and weed diversity between ZUTS-33 and non-genetically modified control soybean HC-3 and ZH-13. Spraying herbicide on ZUTS-33 had no significant effect on arthropod diversity, diseases and rhizobium compared with those treatments of spraying clear water on ZUTS-33, non-genetically modified control HC-3 and ZH-13, and the abundance of weeds were significantly decreased.
转基因作物对农田生物多样性影响评价是其大田释放和获得环境安全证书之前的必要环节。本研究通过大田试验,比较喷施清水及除草剂对转g10-epsps基因耐除草剂大豆ZUTS-33及其受体大豆HC-3和主栽品种大豆ZH-13的大田节肢动物多样性、病害发生、根瘤菌数量及杂草多样性的影响。结果表明: 与对照非转基因大豆HC-3和ZH-13相比,转基因大豆ZUTS-33田间节肢动物多样性指数(百株虫口数、Shannon多样性指数、Simpson优势度指数和Pielou均匀性指数)无显著差异,大豆主要病害发病率和病情指数无显著差异,根瘤菌数差异不显著,大豆田杂草多样性无显著差异;转基因大豆ZUTS-33喷施除草剂与转基因大豆ZUTS-33、非转基因对照HC-3和ZH-13喷施清水相比,节肢动物多样性、病害发生以及根瘤菌数量等差异均不显著,但杂草数量显著降低。.
