问:有人说红粒小麦的品质不如白粒的好,这种说法对不对?(读者杨明)答:小麦品质的好坏与粒色关系不大。小麦籽粒叫做颖果:它由果皮和种子组成。种子包括种皮、无色透明的珠心层、胚和胚乳四个部分。籽粒的颜色是由种皮内色素含量多少而决定的。色素含量多,籽粒颜色就深。 Q: Some people say that the quality of red grains is not as good as that of white grains. Is this not correct? (Reader Yang Ming) A: The quality of wheat has little to do with grain color. Wheat grain is called caryopsis: it consists of peel and seeds. Seeds include seed coat, colorless and transparent beads, embryo and endosperm four parts. The color of the seed is determined by the amount of pigment in the seed coat. More pigment content, the color of the kernel on the deep.
