| description | The purple passion fruit is a fruit species of great importance in high Andean areas, but it can be affected by water deficit conditions. The objective of this study was to determine the effect of the application of brassinosteroids on purple passion fruit grafted on Passiflora maliformis and under water deficit. The plants were subjected to different levels of irrigation (100%, 50% and 25% of the evaporated amount) and some were applied with brassinosteroid analogue (DI-31). The fresh and dry mass of the aerial part and the root, leaf area, height of the aerial part, electrolyte loss, relative chlorophyll content, stomatal conductance, and maximum PSII quantum efficiency (Fv/Fm) were determined. It was observed that water stress negatively affected the height, leaf area, and fresh and dry masses of the plants at 84 days after treatment (dat). On the other hand, the results indicate a positive effect of the brassinosteroids on the height, leaf area, and fresh and dry masses of the plants at the different levels of irrigation at 84 dat. An effect of water stress or the exogenous application of brassinosteroids on electrolyte loss was not detected, but these factors did affect Fv/Fm at 28 dat. These results are important for the formulation of integrated management plans for the cultivation of Passiflora edulis f. edulis Sims in a climate change scenario. |

La gulupa es una especie frutal de gran importancia para las zonas altoandinas, pero se puede verse afectada por condiciones de déficit hídrico. El objetivo de este estudio fue determinar el efecto de la aplicación de brasinoesteroides en gulupa injertado sobre Passiflora maliformis y bajo déficit hídrico. Las plantas fueron sometidas a diferentes niveles de riego (100%, 50% y 25% de la cantidad evaporada) y algunas se aplicaron con análogo de brasinoesteroide (DI-31). Se determinó la masa fresca y seca de la parte aérea y de la raíz, área foliar, altura de la parte aérea, pérdida de electrolitos, contenido relativo de clorofila, conductancia estomática y eficiencia cuántica máxima del PSII (Fv/Fm). Se observó que el estrés hídrico afectó negativamente la altura, el área foliar, y la masa fresca y seca de las plantas a los 84 días después de tratamiento (ddt). Por otro lado, los resultados indican un efecto positivo de los brasinoesteroides sobre la altura, área foliar, y la masa fresca y seca de las plantas en los diferentes niveles de riego a los 84 ddt. No se detectó un efecto del estrés hídrico o la aplicación exógena de brasinoesteroides sobre la pérdida de electrolitos, pero estos factores sí afectaron la Fv/Fm a los 28 ddt. Estos resultados son importantes para la formulación de planes de manejo integrado del cultivo de Passiflora edulis f. edulis Sims en un escenario de cambio climático.
