Editing Germination (section)

=== Dormancy ===
Some live seeds are [[dormancy|dormant]] and need more time, and/or need to be subjected to specific environmental conditions before they will germinate. [[Seed dormancy]] can originate in different parts of the seed, for example, within the embryo; in other cases the seed coat is involved. Dormancy breaking often involves changes in membranes, initiated by dormancy-breaking signals. This generally occurs only within hydrated seeds.<ref>{{cite book | first1 = J Derek | last1 = Bewley | first2 = Michael | last2 = Black | first3 = Peter | last3 = Halmer | name-list-style = vanc | title = The encyclopedia of seeds: science, technology and uses Cabi Series| url = https://books.google.com/books?id=aE414KuXu4gC&pg=PA203| year = 2006| pages = 203| isbn = 978-0-85199-723-0 }}</ref> Factors affecting seed dormancy include the presence of certain plant hormones, notably [[abscisic acid]], which inhibits germination, and [[gibberellin]], which ends seed dormancy. In [[brewing]], barley seeds are treated with gibberellin to ensure uniform seed germination for the production of barley [[malt]].<ref name="Raven"/>
