Soil salinity is considered a serious problem that limits agricultural productivity. Currently, solutions are being sought to mitigate the negative impact of salt on economically important crops. The aim study was evaluate effect foliar application silicon (Si) physiological and epigenetic responses wheat grown under stress conditions. experiment with seedlings established in pots 200 mM NaCl added. After 7 days, fertilizer (200 g L−1 SiO2) used at concentrations 0.05, 0.1 0.2%. Physiological parameters were measured three times. addition caused significant decrease values plants all variants. In sprayed Si conditions, increase CCI selected gas exchange (PN, Ci, E, gs) chlorophyll fluorescence (PI, RC/ABS, FV/Fm, Fv/F0) observed. doses 0.2% showed better mitigating compared dose 0.05%. observed maintained over time. results obtained indicate positive role for fertilization wheat. Epigenetic mechanisms play an regulating gene expression response stress. Changes status methylation 5′CCGG3′ sequence nuclear genome exposed treated different determined by MSAP approach. clear alteration DNA as experimental factors. changes dose-dependent. These modifications may suggest mechanism plant adaptation after application.
