Plant Stress

Over the course of their entire life-cycle, plants don’t usually develop under optimal conditions, but rather face various adverse situations that cause different types of stress, preventing them from achieving maximum yields. In addition, the physiological optimum of a species differs from the so-called ecological optimum, so in each case the plant has to adapt to its habitat's environmental conditions. 

Any environmental factor that impacts the plant, affecting its biochemical and physiological responses and potentially causing occasional harm and injury is considered stress. In general, stress situations trigger a series of compensatory physiological changes to take place within the plant with the purpose of maintaining the vital conditions of the organism.
