Dormancy break refers to the process of interrupting a plant's dormancy, a state of inactivity or reduced metabolic function that occurs in response to unfavorable conditions like cold temperatures. Dormancy break typically happens naturally as environmental conditions improve, but it can also be induced by growers using techniques such as temperature manipulation, light exposure, or chemical treatments. Dormancy break is crucial for triggering growth, flowering, or germination after winter or periods of stress.
