The results of the investigations of the effect of different concentrations of zircon preparations on the growth parameters and CO2-gas exchange of Timothy meadow s. VIC 9 plants are provided. It was shown that in the studied range of concentrations (1x10-'...1x10‘9) presowing treatment of the seeds at the initial stage of development can stimulate or inhibit the process of germination and significantly enhance the growth of Timothy grass starting from the time of tillering. This effect depends on the concentration of active substances and is maintained throughout the experiment. Besides that, the treatment with growth regulators slightly reduces the intensity of the maximum and the optimum of the net photosynthesis in plants, raising their lability to light and temperature conditions by expanding the boundaries of the optimum in the studied environment parameters. A change in the ratio of the gross photosynthesis and respiration caused by the reduction of the respiratory component was noted.
