El presente estudio tuvo como objetivo determinar los caracteres diferenciales en la respuesta fisiológica a la sequía entre variedades de frijol contrastantes en su tolerancia al estrés hídrico. El experimento se realizó en condiciones de invernadero y utilizando tratamientos de sequía como fuente de variación experimental durante dos etapas fenológicas con cuatro variedades. Las respuestas fisiológicas a la sequía fueron diferentes entre las variedades susceptibles y tolerantes, incluso entre estas. De acuerdo con los resultados, la variedad más tolerante fue Pinto Saltillo (PS). La tasa de fotosíntesis, la producción de semillas, la biomasa del follaje (BF) y la raíz pueden ser criterios útiles en la identificación y selección de genotipos tolerantes a este estrés.]]></p></abstract>

The aim of this study was to determine the differential traits in the physiological response to drought among bean cultivars contrasting in their tolerance to water stress. The experiment was performed in greenhouse conditions using drought treatments as a source of experimental variation during two phenological stages with four cultivars. The physiological responses to drought were different between susceptible and tolerant cultivars. According to the results, Pinto Saltillo (PS) was the most tolerant cultivar. Photosynthesis rate, seed production, foliage and root biomass could be used as criteria to identify and select tolerant genotypes to water stress.]]></p></abstract>
