This article studies the effect of salicylic acid (SA) and nitric oxide (NO) on Triticum aestivum L. wheat plants exposed to the influence of high concentrations of copper and zinc compounds. It is shown that heavy metals (HMs) caused a decrease in the growth parameters in the overground and underground plant parts and contributed to a sharp deterioration in the energy balance and the situation regarding oxidative stress. SA and NO exerted a protective effect, which was expressed in the increased ability to accumulate shoot and root mass, stabilize the energy balance, and reduced lipid peroxidation. Resemblance of protective reactions of wheat plants affected by SA and NO appeared as the alteration of energy (Rtot/Pnet and alternative respiration) and antioxidant (MDA) balance of studied plants was identified. The resemblance possibly evidences of common signaling pathway for SA and NO caused by effect of toxic concentrations of heavy metals.
