摘　　要：选用龙单 5、四单 19和吉单 159三个不同熟期的玉米品种做发芽试验 ,控制温度分别为13℃、17℃、2 1℃和 2 5℃ ,研究不同温度条件下玉米种子发芽与经历时间的关系。结果表明 ,各个品种在不同温度条件下的发芽率与经历时间符合生长曲线函数yi=C/ (1+ea +bxi)。three corn varieties (Longdan 5, Sidan 19 and Jidan 159) were used in this experiment to study the relationship between seed germination and time duration under different temperatures. The temperature was controlled at 13℃, 17℃, 21℃ and 25℃, respectively. The results showed that the percentage of seed germination and the needed time at different temperatures were coincident with the growth curve function: y i=c1+e a+bx i

关 键 词：玉米 发芽率 温度 生长曲线
