| 摘 要： | 对比丹玉88、丹玉405、丹玉603、丹玉301等11个丹玉系列主栽品种在常温和变温条件下发芽率的变化。结果表明：丹玉201和丹玉301两个品种对温度变化不敏感，其它品种的发芽率在变温条件下显著降低，证明变温条件对玉米种子发芽率产生较大影响；不同品种在常温条件下的发芽率存在差异，但差异不大，品种在变温条件下的发芽率差异大于在常温条件下。品种对温度变化的敏感程度存在显著差异。这些数据为确定东华北春播区玉米适时播期提供理论依据。

| Abstract: | Eleven leading maize varieties were adopeted to study the germinating percentage under 25 ℃ normal temperature and 10 -25℃changeable temperature conditions. The results showed that germination-rate of Danyu201 and Danyu301 was insensitive to temperature change, while germinating-percentage of other varieties decreased greatly. It confirmed that germinatiion rate of maize was affected by changeable temperature. And the difference of germinating-percentage between cuhivars under normal temperture was smaller than the distinctness under changeable temperature. It also concluded that there were significant differences between cuhivars in degree of sensitivity to temperature change. Those data wre useful for corn production in the north- ern spring-seeding areas. |
