It is shown that before sowing treatment of triticale seeds with the growth regulators epin and zir con resulted in an increase in the F 742 /F 686 ratio of the stationary fluorescence intensities of plant leaves at the wavelength bands of 742 and 686 nm corresponding to the maxima in the leaf fluorescence spectrum. Triticale under the treatment of seeds with growth regulators showed higher chlorophyll content, higher productivity, and higher indices of crop yield.
