The effect of methyl jasmonate (MeJA, 10 μM) seed treatment on seed germination, growth and some parameters of photosynthesis and water metabolism in wheat (Triticum aestivum L.) plants of the Zlata variety grown at optimal (5 mg/kg) or excessive (46 mg/kg) zinc content in the substrate was studied. It was shown that elevated zinc concentrations inhibited shoot growth and led to a decrease both in chlorophyll content and transpiration intensity. MeJA seed treatment stimulated germination, but slightly inhibited plant growth during the tillering phase at optimum zinc content in the substrate. Conversely, at higher zinc levels, MeJA seed treatment reduces its inhibitory effect on plant growth and transpiration rate.
