| 摘 要： | 应用灰色关联度分析方法，对玉米杂交种“棒三叶”光合性状间的相关性进行了分析。结果表明：与玉米杂交种“棒三叶”光合速率最为相关的性状是叶长，其后依次是长宽比、叶向值、叶面积、叶片干重、叶绿素含量、叶厚、比叶重、叶宽。玉米杂交种“棒三叶”光合性状间具有复杂的相互关系。 |
| 关 键 词： | 玉米杂交种 棒三叶 光合速率 农艺性状 灰争关联度分析 |

| Abstract: | The correlation of photosynthetic charateristics of three ear-leaves of hybrids of corn with the analysis of grey correlation degree. The results showed that the magnitude on effects of vary characters on PN in turn was length, length/wide, value of orientation, area, weight, concentration of chlorophyll, thickness, specific leaf weight and wide of three ear-leaves. And the correlation is complex between photosynthetic characteristics of three ear-leaves of corn. |
| Keywords: | Maize hybrid Three ear-leaves PN Agronomic character Grey correlation degree analysis |
