| description | Proline is an amino acid that accumulates in plants in response to stress conditions. Exogenous application of proline has been reported to increase stress tolerance. An experiment was conducted to evaluate the effect of different exogenous proline solutions applied to melon seedlings grown under saline stress. Four concentrations of proline were evaluated: 0, 5, 10 and 20 mM. Plants were grown at 8.0 dS m-1 electrical conductivity. Plants treated with 10 and 20 mM proline showed higher proline content as well as increased growth parameters. Chlorophyll content was higher in the 10 mM treatment. The results suggest that exogenous application of 10 and 20 mM proline allows plants to increase salt tolerance response. |

Exogenous application of proline has been reported to increase stress tolerance.

La prolina es un aminoácido que se acumula en plantas en respuesta a condiciones de estrés. Se ha reportado que la aplicación exógena de prolina aumenta la tolerancia al estrés. Se realizó un experimento para evaluar el efecto de diferentes soluciones de prolina exógena aplicadas a plántulas de melón cultivadas en estrés salino. Se evaluaron cuatro concentraciones de prolina: 0, 5, 10 y 20 mM. Las plantas se cultivaron con una conductividad eléctrica de 8,0 dS m-1. Las plantas tratadas con prolina 10 y 20 mM tuvieron un mayor contenido de prolina así como un aumento de los parámetros de crecimiento. El contenido de clorofila tuvo el valor más alto para el tratamiento 10 mM. Los resultados sugieren que la aplicación exógena de prolina 10 y 20 mM permite aumentar la respuesta de tolerancia al estrés salino. EEA AMBA Fil: Castañares, José Luis.
