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.
Changes in oxygen, light, temperature, soil chemistry, and/or humidity each may play a role in triggering germination. The effect of any environmental stimulus on a seed depends on its own unique genes as determined by the evolutionary history of its ancestors and any new mutations it may carry.
