不同类型、子粒颜色的玉米经过控制的互相授粉,当代果穗上子粒原有的粒型、色泽按基因独立分配规律发生改变。不同型的甜玉米,经过互相授粉,子粒消失其原有的甜质子粒的特征。果皮颜色不参与花粉直感,也不受花粉直感的影响。不同子粒颜色的玉米可因花粉直感作用使果穗上子粒的体积和重量增大。 Different types of grain color of corn under the control of each other pollination, contemporary ear particles on the original grain size, color distribution according to the laws of gene-independent changes. Different types of sweet corn, pollinated each other, the particles disappear the characteristics of the original sweet proton. Peel color does not participate in the sense of pollen directly, nor is it affected by the sense of pollen. Different grain color of corn can be due to the direct effect of pollen on the ears of the grain size and weight increase.
