| 摘 要： | 玉米的产量是由多个因素共同作用的结果，果穗产量性状是其直接表现。玉米植株中部叶片尤其是穗位叶的光合性状对籽粒产量的形成具有重要作用。因此，分析玉米穗位叶光合性状与玉米杂交种产量性状间的相互关系对选育高产、优质、抗病、广适玉米新杂交种具有重要意义。此文应用灰色关联度分析方法，对玉米杂交种穗部产量性状与穗位光合性状间的相关性进行了分析。结果表明：与玉米杂交种单穗粒重最为相关的穗部光合性状是穗位茎节长，其次是叶面积、叶长、光合效率和比叶重等。对玉米杂交种穗部产量性状综合影响较大的穗位光合性状有穗位茎节长、叶长、比叶重等。

| Abstract: | The photosynthetic characteristics of ear on corn play an important role in yield formation of corn. Application of grey relational analysis method, the correlation of yield characteristics and photosynthetic characteristics of ear on corn were analyzed. The results showed that the magnitude on effects of vary photosynthetic characters on weight per Ear in turn was ear stem length, area, length, PN, specific leaf weight, wide, concentration of chlorophyll, ear position, plant height, value of orientation, e... |
