水稻（Oryza sativa L.）在开花后4 ~ 32天，每隔4天收集3个品种3对不同蛋白质含量的品系的叶片。分析样品的蛋白质、游离氨基氮、核糖核酸、蛋白酶活性和核糖核酸酶活性。此外，还测定了这三对品系完整籽粒掺入氨基酸的能力。游离氨基态氮的最大水平和能力的发展中国家的粮食纳入氨基酸一致被认为是较高的样品在成熟的粮食中的蛋白质含量高。在高蛋白样品中，籽粒中的核糖核酸含量往往较高。
Rice grains (Oryza sativaL.) from three varieties and three pairs of lines with different protein content were collected at 4-day intervals from 4 to 32 days after flowering. The samples were analyzed for protein, free amino nitrogen, ribonucleic acid, protease activity, and ribonuclease activity. In addition, the capacity of the intact grain to incorporate amino acids was determined for the three pairs of lines. The maximal level of free amino nitrogen and the capacity of the developing grain to incorporate amino acids were consistently found to be higher in the samples with the high protein content in the mature grain. The ribonucleic acid content of the grain tended to be higher in the high protein samples.
