Abstract
Con el objetivo de evaluar cuatro bioestimulantes en la inducción de la resistencia sistémica en pepino (Cucumis sativus L.) y tomate (Solanum lycopersicum Mill.) en monocultivo y cultivo asociado en invernadero, fueron aplicados cinco tratamientos en tres estadios de desarrollo (crecimiento, floración y fructificación): T1 Bioremedy (2.0 g/L), T2 Grandsil (2.0 g/L), T3 Testigo (agua) T4 Fossil (5.0 g/L), T5 L-amino (2 cm3/L). Los tratamientos fueron distribuidos en arreglo factorial 3 x 5 y evaluados en un diseño experimental Completamente Aleatorio. Cada unidad experimental estuvo constituida por tres hileras. Las variables de respuestas fueron: altura de planta (cm), diámetro de tallo (mm), número de frutos por planta, volumen del fruto (cm3) y peso de fruto (kg). Los resultados, pepino en monocultivo no presento diferencias notables para ninguna de la variable evaluadas, con excepción de la altura de planta, se observó diferencias significativas al P<0.05 de probabilidad, Bioremedy, L-amino y testigo fueron los mejores. En monocultivo de tomate, hubo diferencias significativas al P<0.05 de probabilidad para todas las variables, destacándose a Bioremedy para altura de planta, diámetro de tallo, peso de fruto diámetro de fruto y número de fruto. En el cultivo asociado tanto el pepino como el tomate con diferencias significativas al P<0.05 de probabilidad para todas las variables evaluadas, destacándose al Bioremedy como el mejor.
In order to evaluate four biostimulants in the induction of systemic resistance in cucumber (Cucumis sativus L.) and tomato (Solanum lycopersicum Mill.) in monoculture and associated greenhouse cultivation, five treatments were applied at three developmental stages (growth, flowering and fruiting): T1 Bioremedy (2.0 g/L), T2 Grandsil (2.0 g/L), T3 Control (water), T4 Fossil (5.0 g/L), T5 L-amino (2 cm3/L). The treatments were distributed in a 3 x 5 factorial arrangement and evaluated in a completely randomised experimental design. Each experimental unit consisted of three rows. The response variables were: plant height (cm), stem diameter (mm), number of fruits per plant, fruit volume (cm3) and fruit weight (kg). The results, cucumber in monoculture did not present notable differences for any of the evaluated variables, with the exception of plant height, significant differences were observed at P<0.05 of probability, Bioremedy, L-amino and control were the best. In tomato monoculture, there were significant differences at P<0.05 for all the variables, with Bioremedy standing out for plant height, stem diameter, fruit weight, fruit diameter and fruit number. In the associated crop, both cucumber and tomato had significant differences at P<0.05 for all the variables evaluated, with Bioremedy being the best.
