Activities of ATPase, acid and alkaline pyrophosphatases and phytase in the germs and endosperms of rice seeds of varying germinative power were measured during their swelling and germination. Maximum ATPase activity was found in the cytoplasmic fraction. Activity of pyrophosphatase was higher in the germ and that of phytase in the endosperm. As the swelling and germination continued, the enzyme activity increased. Losses of germinating power during prolonged storage were accompanied by a decline in the activity of the enzymes which, however, never disappeared; the activity of pyrophosphatases was maintained by 55-70% and that of ATPase and phytase by 40-44%.
在不同发芽能力的水稻种子的胚和胚乳吸水膨胀及萌发过程中，测定了ATP酶、酸性和碱性焦磷酸酶以及植酸酶的活性。发现ATP酶活性在细胞质部分最高。焦磷酸酶在胚中的活性较高，而植酸酶在胚乳中的活性较高。随着吸水膨胀和萌发的持续，酶活性增加。长时间储存期间发芽能力的丧失伴随着酶活性的下降，然而酶活性从未消失；焦磷酸酶的活性维持在55 - 70%，ATP酶和植酸酶的活性维持在40 - 44%。
