| 摘 要： | 以9个玉米品种为材料，在夏播条件下进行叶片出生数与穗分化关系的试验观察，结果表明：各品种的雄穗与雌穗分化时期之间均有着明显的对应关系；总叶片数相同的品种，其各出叶数所对应的雄、雌穗分化时期是相同的；不同品种的叶龄指数所对应的雄、雌穗分化各时期是基本一致的。结果揭示了夏玉米出叶数、叶龄指数与穗分化进程的对应关系，为夏玉米高产栽培提供了理论依据。 |
| 关 键 词： | 夏玉米 出叶数 叶龄指数 穗分化 |

| Abstract: | With 9 maize varieties used as materials, the relationship between the leaf emergence number and the spike differentiation was studied under the summer sowing. The results indicated that the male spike was obviously related with female spike differentiation stages. For variety that total leaf number is same, its emerged leaf number right related to the male and female spike differentiation stages is same. Leaf number index right should the spike differentiation all stages within different variety were very similar. The results elucidated the relationship between emerged leaf number, leaf number index and spike differentiation progress. The fundamental was supported for high yield cultivation in summber maize. |
| Keywords: | summer maize emerged leaf number leaf number index spike differentiation |
