What is plant stress?
Normally, plants do not grow in optimum conditions during their life cycle, but suffer many adverse situations that cause different types of stress, and prevent them from reaching maximum development. In addition, the physiological optimum for any one species differs from what is known as the ecological optimum, and therefore in each particular case, the plant has to adapt to the environmental conditions prevailing in its habitat.
Stress is considered as a change in any environmental factor that has an impact on the plant by affecting its biochemical and physiological response to such changes, and may on occasions lead to damage or injury.
In general, the stressful situations cause a series of physiological changes in the plant to offset these situations that are intended to maintain the plant’s vital functions.
