对寒地水稻不同品种、不同粒位子粒灌浆过程进行了 Logistic方程的拟合 ;比较了最大灌浆速率、最大灌浆速率期、平均灌浆速率等与子粒灌浆有关参数的品种间、粒位间的差异 ;分析了子粒灌浆特性参数间的相互关系
Logistic equation was used to fit the grain filling process of different varieties and grain positions in cold region. Logistic equation was used to compare grain filling and grain filling with maximum filling rate, maximum filling rate and average filling rate The relationship between grain filling parameters was analyzed
