Concentrations of cob sucrose and TNC were higher for apical than for basal cob and higher for TNG 351 Than for TNG Y 365 during mid and late kernel-filling. 上位穗轴之蔗糖与非构造性碳水化合物浓度在子粒充实中、后期高于下位穗轴，并以台农3别号显著高于台农育365号，证明光台物质可顺利转移至上位穗轴，且叶片供源能力充裕，并非限制子粒充实之因子；

Corn hybrids Tainung 351 (TNG 351) and Tainung Yu 365 (TNGY 365) were used as experimental material.The two hybrids have the same maternal inbred but different paternal inbred. 摘要本试验以单杂交玉米台农351号及台农育365号为材料，两者具相同母本及不同父本，且后者子粒充实性优于前者；
