What is dormancy?
1 Answer
Dormancy is a strategy of higher plants to survive adverse conditions by pausing growth and development.
Explanation:
In plant physiology dormancy is a period of arrested plant growth which occurs in different organs like seeds and buds.
Dormancy is controlled by both genetic and environmental factors. Natural hormones known as gibberellins break bud dormancy in most cold requiring plants.
Gibberellins, cytokines, and ethylene are natural hormones that are involved in breaking seed dormancy. Mature seeds contain a complete embryo along with a reserve food supply and are formed within ripened fruit. If it is not for germination inhibitors present in the fruit or seed, the seeds would begin to germinate while still in the fruit.
The plant hormone abscisic acid plays an important role in establishment and maintainance of dormancy.
