The effect of drought and salt stress was studied by generating the same water potential (Ψ) with polyethylene glycol (PEG) and sodium chloride (NaCl). In addition, as the magneto-priming was demonstrated to be a non-invasive method to improve germination, the study was performed by comparing water absorption of magnetically treated and non-treated seeds of triticale (X Triticosecale Wittmack) under stress conditions. Seeds water uptake was inversely proportional to the PEG and NaCl concentration, although the absorption was greater for magnetically treated seeds in comparison to the untreated ones (increments up to 11%). Seeds magnetically treated absorbed more water under the influence of NaCl than PEG, especially with low Ψ levels. The adverse effect of salinity and drought on water absorption can be circumvented by exposing seeds to magnetic treatment with a stationary magnetic field induction of 3.71 mT (milliTeslas) during 10 h.
