Effects of NaCl on Hydroponic Cultivation of <i>Reichardia picroides</i> (L.) Roth

Wild edible plant species are often more tolerant to salinity than many crop plants. Considering the salinization of irrigation water that is progressively affecting the Mediterranean region and the market demand for new plant foods, the cultivation of wild edible species could represent a valid alt...
