禾谷类作物的籽粒胚乳里含有初级营养储存物,后者在种子萌发后即变成提供幼苗生长的易流动物质。胚乳储存物的这种可移动作用,受酶水解作用及其后输往到生长幼苗的降解物运输作用的影响。萌动大麦籽粒的早期生理学研究证明,酶水解作用与胚乳营养贮存物的溶解作用,均受生长中的胚及糊粉细胞的双重控制。后来的研 The cereal endosperm of cereal crops contains primary nutrient stocks that become readily flowable substances that provide seedling growth after germination. This moveable effect of endosperm storage is affected by enzymatic hydrolysis and subsequent transport of degradants transported to growing seedlings. The early physiology studies of sprouted barley grain demonstrate that the enzymatic hydrolysis and the solubilization of the endosperm nutritional stock are both controlled by the growing embryo and aleurone cells.
