Comment
A dormancy process (GO:0022611) is a developmental process in which dormancy (sometimes called a dormant state) is induced, maintained or broken. Dormancy is a suspension of most physiological activity and growth that can be reactivated. This term only applies to a whole plant in the sporophyte stage, not to the dormant stage of a seed, bud, or other plant structure. Dormancy of a plant may be preceded by the senescence of its parts such as leaves in woody plants or most of the shoot system herbaceous perennials and by the formation of dormant buds. The end of dormancy in a sporophyte is marked by resumed growth of buds and/or growth of vascular cambium. The dormant stage may be a response to environmental conditions such as seasonality or extreme heat, drought, or cold. Examples of a sporophyte dormant stage are the resurrection plants Selaginella lepidophylla (a lycopod) and Craterostigma plantagineum (an angiosperm) while they are dessicated, and deciduous woody plants and herbaceous perennials or biennials that have a dormant stage in response to drought or cold.
