dc.descriptionHydroponic lettuce (Lactuca sativa) is a form of plant management that allows cultivation without soil. This technique mainly produces herbaceous plants that take advantage of non-traditional sites or areas without neglecting them, and at the same time keeping in mind the needs of the plants, such as light, temperature, water, nutrients, planting density and pest and disease problems that will strongly affect the crop yield.The objective of the study is to determine the effect of salicylic acid and brassinosteroids as inducers of resistance to salinity in the province of Los Ríos, at the Technical University of Babahoyo, a project carried out at the Faculty of Agricultural Sciences, through a greenhouse study located within the experimental type faculty, which has an adaptable system for hydroponics, where 9 treatments were carried out with an electrical conductivity of 3.5 and 7.0 due to high amounts of salt in the water, and applying 2 that they were salicylic acid and brassinosteroids, the data of plant height, number of leaves, leaf size, root length, dry and fresh weight, chlorophyll and yield were evaluated, all this was evaluated using the Tukey test in infostat. The results obtained from these data indicate that water with a high percentage of salinity is directly detrimental to the growth of lettuce crops. Salicylic acid has been shown to give the most favorable results when exposed to high salinity in water, even when these products contribute to control potential saline stress in lettuce crops.es_ES

dc.description.abstractLa lechuga hidropónica (Lactuca sativa) es una forma de manejo vegetal que permite el cultivo sin suelo. Esta técnica produce principalmente plantas herbáceas que aprovechan sitios o áreas no tradicionales sin descuidarlos, y a su vez tener presente las necesidades de las plantas, como luz, temperatura, agua, nutrientes, densidad de siembra y problema de plagas y enfermedades que incidirán fuertemente en el rendimiento del cultivo. El objetivo del estudio es determinar el efecto del ácido salicílico y brasinoesteroides como inductores de resistencia a salinidad en la provincia de Los Ríos , En la universidad Técnica de Babahoyo , proyecto realizado en la facultad de ciencias agropecuaria, mediante un estudio de invernadero localizado dentro de la facultad de tipo experimental , que cuenta con un sistema adaptable para la hidropónicas, en donde se llevó a cabo 9 tratamientos con una conductividad eléctrica de 3,5 y 7,0 debido a altas cantidades de sal en el agua, y aplicando 2 que fueron ácido salicílico y brasinoesteroides, se evaluaron los datos de altura de planta, numero de hojas, tamaño de hojas, longitud de raíz, peso seco y fresco , clorofila y rendimiento, todo esto se evaluara mediante la prueba de Tukey en infostat. Los resultados obtenidos a partir de estos datos indicaron que el agua con un alto porcentaje de salinidad es directamente perjudicial para el crecimiento de los cultivos de lechuga, Se ha demostrado que el ácido salicílico brinda los resultados más favorables cuando se expone a una alta salinización en el agua, aun cuando estos productos aportan a controlar el estrés salino potencial en los cultivos de lechuga.es_ES
