中文摘要：转基因大豆品种在世界范围内的应用逐年增多，这表明其基因型的优良性。对大豆育种来说，转基因品种在杂交过程中的使用依赖于检测转基因性状的能力。在含草甘膦的湿润基质中进行发芽试验是有效且成本低的方法，然而，这是否是一种无损检测品种的方法。本文的研究目的是应用生物测定法检测抗除草剂的种子，并评估作物的营养和生长发育。研究发现，抗草甘膦和草甘膦敏感作物在除草剂施用的初始阶段会受影响，然而，抗草甘膦作物在营养和生长发育过程可以完全恢复，草甘膦敏感作物智能部分恢复。
外文摘要：The adoption of genetically modified soybean cultivars is increasing annually around the world, which indicates the excellence of these genotypes. For soybean breeding, the use of such cultivars in a backcross program relies on the ability to detect the transgenic trait. The germination test in a moistened substrate with glyphosate is effective and of low cost, however, wonders whether this is a non-destructive method to check cultivars. The objective of this study was to apply a bioassay for detection of herbicide-tolerant seeds and to evaluate the vegetative and productive development of the plants. It was observed that both glyphosate-tolerant and glyphosate-sensitive plants were affected in the initial stages of development in accordance with the herbicide application rate. However, whereas tolerant plants fully recover both in vegetative growth and production during the cycle, sensitive plants recover partially, producing smaller plants with lower yield as a consequence of the herbicide application rate.
