Watercress – cultivation methods and health effects

摘要: Watercress, Nasturtium officinale R. Br., is a native water or semiaquatic plant that has high nutrient density. Physiologically relevant are the various glucosinolates, which possess positive health effects in form of their thio- and isothiocyanates. In an interdisciplinary project, we aim to develop hydroponic, finally aquaponic, circulatory cultivation system study watercress. humans, there lack data-based knowledge on potential beneficial Growth watercresswas followed during one season open-door hydroponic system. Watercress was also cultivated greenhouse different substrates with concentrations nutrients salt. The biomass production strongly dependent temperature. glucosinolate contents differ significantly growing season, especially flowering. naturally grows rich fresh waters, however, when at NaCl up 120 mM gain still high. human proof of-concept study, indications for antioxidant anti-inflammatory watercress were observed already after single dose intake (85 g). Further vivo vitro studies planned its metabolic activity.
