The Analysis of Influence of Fluctuations Level on Resistance Plants to Action Stress-Factors

Mathematical model of adaptation in plants was devised. This model was based on qualitative descriptions of adaptation process of Veselova and co-authors (1993). Model included basic and stressful states, which differed on resistance to action stress-factors. The analysis of model had shown that various intensity of stress-factor and forms of fluctuation dependence induce mono- or diphase changes of resistance. Experimental verification of model had shown that cold-resistance dependence from a level of fluctuations in pumpkin has diphase character. This experimental result supports theoretical results of analysis of mathematical model.
