Oat seeds with a higher protein content as a result of chemical applications in 1967 yielded 21 to 42 percent more grain in 1968. Wheat seed, whether from Michigan, Illinois, or Mexico, that contained more protein as a result of field applications of chemicals or nitrogen developed into larger seedlings. The content of protein in the seed correlated with subsequent growth and yield, indicating that the amount of endogenous protein or of a proteinaceous moiety, which can be controlled, may be an important factor in subsequent yield of major agronomic crops.
1967 年经过化学处理的燕麦种子，其蛋白质含量更高，1968 年的谷物产量增加了 21%至 42%。经过田间化学物质或氮处理后蛋白质含量更高的密歇根、伊利诺伊或墨西哥小麦种子，长成的幼苗更大。种子中的蛋白质含量与随后的生长和产量相关，这表明可控制的内源性蛋白质或蛋白质部分的数量可能是主要农业作物后续产量的一个重要因素。
