| 摘 要： | 以中、晚熟小麦品种（系）为对照，对早熟高产小麦灌浆期干物质积累和子粒灌浆过程进行了研究。结果表明，早熟、高产小麦品种在子粒灌浆期较多地利用了花前贮藏的营养物质，对同化物的利用较协调；灌浆高峰来得迟，高峰峰值高；高峰出现后，灌浆速率下降稍快于中、晚熟类型小麦品种（系），但在花后35d内，灌浆速率仍显著高于中、晚熟类型小麦品种。 |
| 关 键 词： | 小麦 早熟 高产 灌浆 |

| Abstract: | Grain grouting character was studied on eight high grain yield wheat cultivars which popularized in Guanzhong area belong to early,medium and late-maturing.The result showed that: the high grain yield of early-maturing wheat cultivars take much use of nourishment prefloral storage and usage of photoassimilates correspond during grain grouting period,grouting peak is late and the peak value is high,after peak,grouting rate drop quicker than medium-late maturing cultivars,but grouting rate is high remarkably than medium-late maturing cultivars,till about 35 days postfloral. |
| Keywords: | Wheat Early-maturing High grain yield Grain grouting |
