Sarcocornia species grow naturally on salt marshes, are extreme salt-tolerant halophytes and considered as a promising vegetable to human consumption due their adequate nutritional profile, levels of bioactive components, including polyphenols, and functional properties, such as antioxidant [1]. Targeting its commercial cultivation, this work aimed at the optimization of the asexual reproduction of Sarcocornia perennis (Mill.) A. J.Scott ecotypes, under an IMTA system. Cuttings were collected in the Southern Portugal (Algarve), submitted to hormone rooting treatments, planted on substrate (coir and perlite) and maintained waterlogged on an IMTA system with different salinities. The plant survival was evaluated and collected biomass was evaluated for productivity (amount of produced biomass) and minerals, while total phenolics and radical scaveging activity (RSA) were determined on methanol extracts. Cuttings had higher rooting rates with hormone treatment (87,5%). Plants had better productivity on the lower salinity. Sodium was the major element (> 70 mg/g), followed by K, Mg and Ca. The highest total phenolics content, RSA and copper and iron chelating activity were observed on methanol extracts from plants grown on lower salinity.
