| 摘 要： | 通过分析灌浆期籽粒干物重，并将其与Logisac方程拟合，研究了鲜食糯玉米籽粒的灌浆规律和特征。结果表明：鲜食糯玉米籽粒的灌浆速度随灌浆日期呈现出慢-快-慢的“S”型曲线变化趋势，开始灌浆后的第三十四天灌浆速度最大，为8.57g／d。这一结论可作为确定鲜食糯玉米鲜穗适宜采收期的参考。

| Abstract: | Based on the analysis of dry matter yield of grain during grain filling stage of fresh food waxy corn,the date were fitted by the Logistic equation to study the law and characteristics of grain filling.The results show that the grain filling rate presented the"s"curve,that is,the trend of slow-fast-slow with the development of grain filling dates.And the grain filling rate reached the largest at the 34th day,and it was 8.57 g/d.This conclusion could give some references for determining the optimal harvest time of the fresh ear of fresh food waxy com. |
