Antistress activity of plant growth regulator Epin-extra

The physiological activity of the plant growth regulator Epin-extra is investigated under conditions of sodium chloride salinity, cadmium stress, and low temperature. Epin-extra lessens the negative effect of stress factors on growth of spring wheat, Welsh onion, and cabbage: it reduces the level of cadmium-induced chromosome aberrations and concentration of this metal in plants exposed to a cadmium acetate solution. An increase of the level of expression of the cabbage cold shock protein gene (CSP5) under the effect of the bioregulator is established by the real-time PCR method with the use of interprimer fluorescence resonance energy transfer.
