Growth areas are not a tool to stop development; rather, they are used to geographically indicate where more development is appropriate and public Q. What is the Experience With Growth Boundaries in Other Areas? A. Oregon created urban growth boundaries as part of its state and regional land use policies.
Stage One - Hydration and Metabolism. In the first stage of germination, seeds begin to absorb water, a process called imbibation.. The seed coating softens as it absorbs water, and the seed then begins to metabolize, as the water triggers release of an enzyme that speeds cellular respiration, where starch is transformed into sugar.
Germination process and soil temperature. Seed absorbs about 30 percent of its weight in water; temperature does not affect that process. But temperature does affect growth of both the radicle (first root) and coleoptile (shoot).With soil temperatures below 50 F, seeds readily absorb water but do not initiate root or shoot growth.ut temperature does affect growth of both the radicle (first root) and coleoptile (shoot).
