Evaluación del tiempo de exposición de luz leds, en las características agronómicas de la fresa (Fragaria ananassa), variedad Albión, en el cantón Tisaleo

Abstract

The strawberry (Fragaria ananassa) is characterized as one of the main fruits consumed worldwide because it has high levels of vitamins, fiber and other nutrients that are essential for good nutrition, and also because of its organoleptic importance, present in the fruit is used as a fresh or processed product either in the production of preserves, jams, wines and other products. The present research was developed with the purpose of evaluating the effect of LEDS artificial light exposure on the agronomic characteristics of the strawberry crop, for which an experimental design of divided plots with three treatments and three replications was implemented. Positive results were obtained for the study variables such as number of leaves, leaf area, which were reported at 30 and 45 days, as well as determining the days at the beginning of flowering, in which the days after transplanting were counted until the plants presented a true flower bud, for the variable concentration of soluble solids the Brix degrees were determined with the help of a refractometer. For the determination of fruit size, a vernier caliper was used, which allowed us to obtain both the maximum polar and equatorial diameter of the fruit; however, for fruit firmness, a penetrometer was used, and finally, yield. The results showed significant differences between each of the treatments, with T2 being the best treatment in each of the variables studied. It was determined that the incorporation of artificial light LEDS in a period of hours of natural light + 4 hours of artificial light LEDS yielded the best results compared to the other treatments under study.
