Salicylic acid (SA) activated the plant defense response in potato against phytoplasma attack, reduced infection symptoms, favored photosynthates translocation and improved the quality of tubers. SA induced effects at short and long terms and it was equally efficient when it was first applied on in vitro culture followed of transplanting or directly sprayed on greenhouse conditions. Low levels of exogenous SA (0.1 and 0.001 mM) showed higher biological activity. The reduction of damage was associated to high hydrogen peroxide and ascorbic acid contents, together with reduction of peroxidase activity suggesting an important role of SA on the regulation of these molecules and counteracting the pathogens effects.
