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.
Review Plant hormone interactions during seed dormancy release and germination by Kucera, Cohn, Leubner-Metzger, Seed Science Research 15: 281-307 (2005) Table 1: Seed dormancy and germination of Arabidopsis hormone mutants Figure 2: Hormonal interactions during seed dormancy release and germination. Figure 2. Ethylene and pea seed germination: Increased ethylene evolution accompanies seed germination of many species including P. sativum. 2  We found that Ethylene promotes ethylene biosynthesis during pea seed germination by positive feedback regulation of 1-aminocyclopropane-1-carboxylic acid oxidase (ACC oxidase; ACO).
