Abstract: | Freshly harvested seeds of soybean (Glycine max L. Merr.) orseeds shelled, then dried, were non-viable. Seeds dried in intactpods, even when only 17% of normal size, matured into viableseeds and produced healthy plants. These seeds maintained activityof various enzymes but gained little soluble protein while air-dryingin intact pods. There was a qualitative change in seed proteinsassociated with maturation. Seeds matured in intact pods havea greater proportion of protein as slow-moving bands and havecompletely lost one fast-moving band compared with seeds shelledbefore drying. Seed maturation is a distinct phase of seed production,is independent of the parent plant, and can be imposed on theseed at many stages of development. |
