不同类型玉米子粒灌浆特性分析

以普通玉米、糯玉米、爆裂玉米和甜玉米为材料,用Logistic方程拟合子粒灌浆过程,分析一系列次级灌浆参数。结果表明:不同类型玉米粒重表现为普通玉米>糯玉米>甜玉米>爆裂玉米,不同部位粒重表现为下部>中部>上部。相关分析表明,玉米子粒最终粒重的高低主要取决于灌浆速率的大小,而不是灌浆持续时间的长短。

Analysis on Kernel Filling Characteristics for Different Maize Types

Normal corn, waxy corn, pop corn and sweet corn were used in this experiment. Logistic equation was used to simulate kernel filling processes of four maize types. A series of subsequent parameters of kernel filling were analyzed. The results showed that kernel weight was in the order of normal corn > waxy corn > sweet corn > pop corn among different maize types and basal > middle > apical among different ear positions. Correlation analysis indicated that the final kernel weight of maize rest with the rate of filling mostly, not the duration of filling.
