dormancy

(dor′măn-sē)
Temporary inactivity; e.g., a state of transiently reduced metabolic activity.
dormant, adjective

dormancy

a state in which seeds and other structures (such as underground stems) reduce their metabolic activities to a minimum level during unfavourable conditions (e.g. low temperature, drought) so as to survive until conditions improve. In fungal spores dormancy can be EXOGENOUS, requiring an external stimulus (e.g. presence of nutrients) for germination; or ENDOGENOUS, where dormancy is controlled by an innate property of the spore and is unaffected by the ambient environment when in this state. See GERMINATION for events that occur when seed dormancy is broken.
