Sulfonylurea herbicide resistance did not link to germination feature of seeds in self-fertilized progenies of Schoenoplectus juncoides. However, population dynamics model explained why most of the sulfonylurea resistant accessions show higher seed germination rate than the susceptible accessions. In the isolation of genes relating seed germination or dormancy, VP1 gene was identified in S. juncoides, but the other genes were not identified.

对磺脲类除草剂的抗性与其种子的萌发特性无关。然而，种群动态模型解释了为什么大多数磺酰脲抗性品种的种子发芽率高于敏感品种。在油菜种子萌发或休眠相关基因的分离中，只鉴定到VP1基因，未鉴定到其他基因。
