摘　　要：本文通过遮光实验旨在研究高粱品种2421的光周期性.结果表明该品种对日照长度较为敏感,即在出苗后20d内对日照长度敏感,其临界日长为11～12h,光周期为9～12d.This paper showed that sorghum 2421 is a very photosensitive variety for day length by covering light treament. After exposed seedling, sorghum 2421 is photosensitive for day length in 20 days. Its critical day length is 11-12 hours,and its photoperiod is 9-12 days.
