The processes of the growth of plants after laser irradiation of their seeds before sowing and their cultivation on environments with pro- and anti-oxidants of the lipid peroxidation were investigated with the use of mathematical methods. It is established that the germination of laser photoactivated seeds increases in comparison with the normal seeds, especially on the peroxide environment. Among researched factors of influence on the growth parameters are irradiation, pro- and antioxidants, and also joint influences of these factors. Only the influence of the first two and their interaction are statistically significant. The growth of photoactivated plants is expressed by a mathematical model as a multiplicative function of regression with coefficients which depend on the influencing factors.
Key words: plant growth, laser photoactivation, antioxidants, mathematical model.
