| description | *Passiflora tarminiana* is a climbing glycophyte, native to the Andean region that has tolerance to salinity and moderate water stress. The aim of this study was to evaluate its capacity for sodium excretion as a possible strategy for salinity tolerance and the drought. Salt excretion and excreted ion concentrations were evaluated in plants grown for seven months under various levels of salinity [(NaCl) 2.5, 4.0, and 5.5 dS m^-1^ (25, 40 and 55 mM)] and moderate water stress (33 and 100% moisture in the substrate). The experiment design was completely randomized in a split-plot array, where the plot was determined by the percentage of water saturation (33% and 100%). The ubplot had saturation levels of salinity (EC: 2.5, 4.0, and 5.5 dS m^-1^), with five replicates. The experiment unit consisted of one plant. Salt crystals and structures of the leaf epidermis were evaluated. Salts were excreted in the adaxial leaf surface, possibly because of specialized salt secreting glands. Other structures, such as trichomes and papillae, were also observed, which are believed to also be involved in the salt tolerance of *P. tarminiana*. |

Passiflora tarminiana es una glicofita trepadora, nativa de la región andina que tiene tolerancia a la salinidad y estrés hídrico moderado. El objetivo de este estudio fue evaluar la capacidad para la excreción de sodio como una posible estrategia de esta especie para la tolerancia a la salinidad y a la sequía. La excreción de sal y las concentraciones de iones excretados se examinaron en plantas cultivadas durante siete meses bajo varios niveles de salinidad [(NaCl) 2,5; 4,0 y 5,5 dS m-1 (25, 40 y 55 mM)] y de estrés hídrico moderado (33 y 100% de humedad en el sustrato). El experimento fue llevado a cabo en un diseño completamente al azar con un arreglo de parcelas subdivididas, donde la parcela constituye el porcentaje de saturación de agua (33 y 100%), la subparcela los niveles de saturación de sal (CE: 2,5; 4,0 y 5,5 dS m-1), con cinco repeticiones, y la unidad experimental compuesta por una planta. Se evaluaron los cristales de sal y las estructuras de la epidermis foliar. Las sales fueron excretadas en la superficie adaxial de la hoja, posiblemente debido a las glándulas secretoras de sal especializadas. Se observaron otras estructuras como tricomas y papilas, que se cree que también están implicadas en la tolerancia a la salinidad en P. tarminiana. 2018 2018-05-11T19:00:22Z 2018-05-11T19:00:22Z Journal Article https://hdl.handle.net/10568/92524 en Open Access Sociedad Colombiana de Ciencias Horticolas Hurtado-Salazar, Alejandro, Pereira da Silva, Danielle Fabíola, Ceballos-Aguirre, Nelson., Ocampo, John, Bruckner, Claudio Horst (2018).
