| 摘 要： | 以4个不同玉米自交系为试验材料,采用六种不同播期进行试验。结果表明,不同播期对玉米自交系出苗率影响很大;玉米自交系播种期相差的天数与出苗期相差的天数并不相等,它们之间呈明显正相关;玉米自交系播种期相差的天数并不等于雌雄穗开花相差的天数,它们之间呈明显正相关。

| Abstract: | The experiment is on the basis of 4 different types of corns,which were sowed at six different times.From the result,we can see that the time difference of self-bred seeding time doesn't equal to the time difference of sprouting,however,they are in obviously direct proportion.Different seeding time influences cone self-bred emerging rate greatly.The time difference of self-bred seeding time doesn't equal to the time difference of male and female spike blooming time,however,they are in direct proportion. |

| Keywords: | corn self-bred system seeding time emerging rate female and male spike blooming period |
