Ngosong, C., Halpern, M. T., Whalen, J. K. and Smith, D. L. 2013. Purslane (Portulaca oleraceaL.) has potential for desalinizing greenhouse recirculation water. Can. J. Plant Sci. 93: 961-964. Recirculating fertigation solutions improves the environmental sustainability of hydroponics-based vegetable production in Canada. Purslane is an edible halophyte with proported medicinal benefits that could absorb excess salts from recirculation water. It grew well in hydroponic solutions with up to 1000 mg NaCl L^-1. Greatest Na absorption occurred during earlier vegetative growth.
