AbstractSince the application of poor-quality irrigation water is frequently the cause of the salinization of the soils given over to the cultivation of roses in Tenerife we carried out an irrigation trial with two waters of high salinity at concentrations of 15,70 meq/l of Cl-, and 13,60 meq/l of CO$H- respectively. Both types of water caused a significant reduction in the yields of the cultivar "Sonia", which was greater in the treatment with chlorinated water. The quality of the flower (expressed as a percentage of extra flowers) decreased considerably in the plants treated with bicarbonated water, and was reduced by 50% in relation to the control, in the case of rose bushes treated with chlorinated water. In neither of the two cases were visible symptoms of salt toxicity noticed.
