Altering the level of phytic acid phosphorus by nutritional means had no effect on the ability of soybean (Glycine max L. [Merr.], cv ;Williams 79') seeds to germinate under laboratory or greenhouse conditions. Dry matter moved out of the cotyledons at similar rates whether the germinating seeds initially contained low (0.19), medium (0.59), or high (1.00 milligram per seed) phytic acid phosphorus. Growth of roots and shoots from 3 to 9 days after planting was similar for seeds containing low and medium levels of phytic acid phosphorus. The medium level of phytic acid resembles that found in field-grown seed, so it is clear that soybean seeds normally contain a phosphorus reserve far above that needed for germination and early seedling growth.
通过营养手段改变植酸磷水平，对大豆（Glycine max L. [Merr.], cv ；Williams 79'）种子在实验室或温室条件下的发芽能力没有影响。无论发芽种子最初含有低（0.19）、中（0.59）还是高（1.00 毫克/粒）植酸磷，干物质从子叶中移出的速度相似。播种后 3 至 9 天，根和芽的生长对于含有低和中植酸磷水平的种子是相似的。中植酸磷水平类似于田间生长种子中的水平，因此很明显，大豆种子通常含有远远超过发芽和早期幼苗生长所需的磷储备。
