摘要

Abstract

Eleven leading maize varieties were adopeted to study the germinating percentage under 25 °C normal temperature and 10 ~ 25 X. 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 cultivars under normal temperture was smaller than the distinctness under changeable temperature. It also concluded that there were significant differences between cultivars in degree of sensitivity to temperature change. Those data wre useful for corn production in the northern spring-seeding areas.
