Evaluación de yodo agrícola y ácido salícico como biofortificantes en el desarrollo vetegativo de plantas de fresa (Fragaria ananassa)

Abstract

In Ecuador, strawberry production is very extensive, since Pichincha has 400 cultivated hectares, in Tungurahua they cultivate 240 hectares and finally in the provinces of Chimborazo, Cotopaxi, Imbabura and Azuay the production exceeds 40 hectares, likewise this fruit has many benefits Since it has great nutritional value, such as Vitamin C, it also fights anemia and is very beneficial for growing children. For this reason, it is very important that plants grow healthy and resistant to any type of disease stress, increasing their nutritional value through biofortifiers. Well, this is how the idea of this study arose, evaluating the vegetative state of the strawberry (Fragaria ananassa), applying agricultural iodine (YONEX) and salicylic acid (BRAX-T), in three doses: 1.0; 1.5 and 2.0 cc/L. We worked in a net experimental area of 260 m² and the experimental design of complete randomized blocks was carried out in a 3x2+1 factorial arrangement with three repetitions, where 21 treatments were analyzed, in each treatment there were 60 plants. The variables under study were the number of leaves per plant, petiole diameter, petiole length, plant crown diameter, days to flowering, number of flowers per cluster and chlorophyll quantification, treatment data. they were taken 15 days after the last application, then they were analyzed in Infostat, through the Tukey tests, where concrete results were obtained, such as the most suitable product and the most suitable dose, where P1 ( YONEX) according to the statistical analysis was the best product in a dose of 2.0 cc/L (D3) and finally in the total chlorophyll variable, none of the two products YONEX (agricultural iodine)and BRAX-T (salicylic acid) had an influence, since we did not find significant differences.
