One of the important factors present during any deterioration or stress is electron transfer inducing the production of free radicals which are responsible for energy production. A reduction of the potential of various redox couples in a cell could be viewed as a trigger to activate cellular switchboards that move the cell from proliferation through various physiological stages into apoptosis and finally necrosis equilibrium . The redox couples are important for all living systems vitrified or hydrated they contribute to stress tolerance and manage development and by this the life cycle on a cellular level. The germination process requires energy which is provided by the environmental temperature and in the next step by the energy of the double phase shifting of the water front under defined temperature conditions. The entered and in this way produced energy activates a whole range of reactions including hydrolysis and biosynthesis as concomitant processes increasing as a consequence also the energy. When the biochemical reactions in imbibed seeds reach a critical point inducing cell division germination commences giving as a product a new plant. The next phase is characterized by the distribution of water and substances from hydrolysed seed substance denoted as the plant growth - biosynthesis. In comparison to the energy introduced by hydration processes the free energy of hydrolysis and particularly of biosynthesis have significantly lower absolute values. The domination of exergonic reactions is the release of the necessary energy and the more intensive they are the higher is the growth potential of the system. From that point of view water with its characteristics redox signals and substance conversion including environment are crucial points of .
