| 摘 要： | 对耐旱棉花品种棉晋13号和中棉12号的不同种子质量对棉花发芽势、发芽率、田间出苗诸因素的影响进行了研究。结果表明，大粒种和中粒种的发芽势、发芽率、种子充实度、单株于物质重、根冠比、出叶速度、叶面积均优于小粒种和混合种，而大粒种和中粒种之间无明显差异。棉晋13号的大粒种和中粒种霜前皮棉比混合种增产11．15％－22．28％，比小粒种增产36．65％－50．33％；中棉12号的大粒种和中粒种霜前皮棉比混合种增产16．85％－27．57％，比小粒种增产38．67％－51．40％。

| Abstract: | The experiments were conducted to study the effects of ed quality on growth and yield of cotton in the field with drought tolerant varieties Jinmian 13 and CRI 12. The bigger and medium size seedsare superior to the smaller seeds and mixture seed in the germinating potential, germination rate, seeddensity, plant for matter weight, R/T, leaf area and leaf emergence velocity. The lint yield before frostof the bigger and medium seeds increased 21. 15% ~ 27.61% and 36.65% ~ 50.33% for Jinmian 13,23.51% ~ 34.57% and 38.67% ~ 51 .40% for CRI12 compared to the seed mixture and smaller seedsRespectively. |
