Abstract
The concentrations of adenosine triphosphate and phytic acid in testa, embryo plus scutellum, aleurone, and endosperm fractions from grain of Triticum vulgare cv. Insignia have been determined during development under both normal conditions and those of water stress. Phytic acid was not detected in the endosperm. In the embryo plus scutellum and aleurone fractions there was a rapid build-up of phytic acid, but the adenosine triphosphate level did not change markedly at this time. These results are not consistent with physiological roles previously suggested for phytic acid other than the role of phytin as a phosphorus and cation store for the germinating seed.
摘要
测定了普通小麦品种“ insignia”籽粒在正常条件和水分胁迫条件下发育过程中，种皮、胚加盾片、糊粉层和胚乳部分中三磷酸腺苷和植酸的浓度。胚乳中未检测到植酸。在胚加盾片和糊粉层部分，植酸迅速积累，但此时三磷酸腺苷水平没有明显变化。这些结果与先前提出的植酸的生理作用不一致，除了肌醇六磷酸作为发芽种子的磷和阳离子储存库的作用。
