| 摘 要： | 为了弄清影响玉米产量性状的主要因素,为玉米生产和育种提供参考,进行了玉米产量构成因素研究。结果表明,玉米穗重、行粒数、吐丝期对穗粒重的影响较大,株高、籽粒含水量对穗粒重的影响较小,行粒数、株高、籽粒含水量、吐丝期均通过穗重间接地对穗粒重产生较大的影响。

| Abstract: | The experiment was carried out to investigate main factors affecting yield characters of maize.The results showed that the factors of ear weight,grain number per row and silking period had the significant effect on grain weight per ear but the factors of plant height and grain water content had the slight effect on grain weight per ear.The factors of grain number per row,plant height,grain water content and silking period had the significantly effect on grain weight per ear by affecting the ear weight. |
