Phaseolus vulgaris L. is a legume of high nutraceutical value, widely cultivated and consumed. However, common bean production faces challenges such as water stress that severely affects its growth and yield. This study evaluated the morphological and physiological response of four native P. vulgaris accessions subjected to different irrigation treatments under greenhouse conditions. A completely randomized design with factorial arrangement was used, evaluating three irrigation frequencies (100%, 50%, 25%) in combination with four accessions (PER1003541, PER1003542, PER1003543, PER1003544). The results showed that with the 25% irrigation treatment, PER1003544 showed a 54.62% decrease in leaf area, while PER1003542 and PER1003543 experienced reductions of 56.56% and 59.24%, respectively. In addition, accession PER1003544 reported a smaller reduction in the number of flowers and pods, with...

El frijol (Phaseolus vulgaris L.) pertenece a la familia Fabaceae, que comprende aproximadamente 150 especies en todo el mundo. El estrés hídrico es una de las principales limitantes para su productividad; sin embargo, se ha estudiado muy poco sobre los efectos de la sequía en el crecimiento y desarrollo de accesiones de frijol que están en proceso de adaptación a las condiciones de la selva peruana. Esta investigación tuvo como objetivo evaluar la respuesta morfológica y fisiológica de cuatro accesiones de frijol (PER1003541, PER1003542, PER1003543, PER1003544) sometidas a diferentes dosis de riego (100%, 50% y 25% de su capacidad de campo). Los resultados mostraron que los factores evaluados influyeron significativamente en los parámetros estudiados, destacándose la accesión PER1003544 por sus mejores características morfológicas y un comportamiento fisiológico superior (...
