在种子萌发过程中，胚产生赤霉素，赤霉素可以刺激糊粉层合成一些酶特别是淀粉酶。
1·The nutrient transported from dorsal vascular bundles first unloaded into apoplast via nucellar projection, then was absorbed by aleurone layer cells;
由背部维管束运来的养分经珠心突起先卸至质外体，其后再由糊粉层细胞吸收；
2·Aleurone layer was the cell layer by which the endosperm assimilated nutrients.
糊粉层是胚乳吸收养分的细胞层。
