为进一步提高优质专用小麦生产水平 ,近两年对强筋小麦品种济南 17进行了剪叶和剪穗试验 ,其籽粒灌浆过程以L ogistic方程拟合 ,分析各处理籽粒灌浆特征表明 :(1)剪叶和剪穗对灌浆时间影响较小 ,而对灌浆速率影响显著 ;(2 )成熟期粒重与最大灌浆速率和平均灌浆速率相关极显著 ,而与灌浆时间相关不显著 ;(3)籽粒灌浆过程的前、中、后三个时期以中期灌浆速率最大 ,对粒重的影响也最大。
In order to further improve the quality of special-purpose wheat production, the strong gluten wheat variety Jinan17 was cut and spike-harvested in the past two years. The grain filling process was fitted by L ogistic equation. The grain filling characteristics of each treatment showed that: (1) (2) The grain weight at maturity was significantly correlated with the maximum filling rate and the average filling rate, but not with the filling time; (3) The grain weight The grain filling rate was the highest in the middle, middle, and last stages of grain filling, and had the greatest impact on the grain weight.
