| 摘 要： | 应用灰色关联分析法对杂交稻秧苗性状之间的关系及其对产量、产量结构的影响进行了研究。结果表明：秧苗性状中相互关系密切的有茎粗、秧苗地上部干重、根量和发根力等；发根力和根量对秧苗其它的性状影响最大；茎粗、秧苗干重、秧苗地上部干重、发根力和根量等与产量的关系较密切；秧苗干重、发根力和根量等对产量结构的影响较大。发根力、根量、茎粗、秧苗干重等是秧苗构成的主要性状，也是秧苗栽培的主攻目标

| Abstract: | Using the method of gray relational grade analysis, the relationship among the characters of big seedlings in hybrid rice and their influence on grain yeild and yeild components were studied. It showed that in all characters of seedlings, stem thickness, aboveground dry matter of seedlings, root-generating ability, number of roots were closely related to each other. The root-generating ability and the number of roots greatly affected the other characters of seedlings. The stem thickness, the dry matter of seedling, the root-generating ability, and the number of roots had a greater influence on grain yield than the others so they are the main characters to obtain a high yield in cultural management. |
