The original general stress concept for living organisms was developed by Hans Selye (Selye, H., 1936) and can be summarized in the following two sentences "all agents can act as stressors, producing each stress and specific action" and "there exist agent specific responses and non-specific general responses (Levitt, J. 1980) defined stress as "any environmental factor potentially unfavorable to living organisms". Plant stress is a state in which increasing demands made upon a plant lead to an initial destabilization of functions, followed by normalization and improved resistance (Larcher W. 1987) and also if the limits of tolerance are exceeded and the adaptive capacity is overworked, the result may be permanent damage or even death (Lichtenthaler HK, 1998). The present concept of stress in plants has been well developed over the past 60 years. Any unfavourable condition or substance that affects or blocks a plants metabolism, growth, or development is regarded as stress. Plant stress may be a state wherever a plant is growing in non-ideal growth conditions and has accumulated demands placed on it.
