Evaluación del uso de ácido giberélico (AG3) en el ciclo fenológico del cultivo de Delphinium elatum después del pinch, en tres variedades

Abstract

Currently, improving the yield and production of a crop has become an advantage for Ecuador as one of the flower exporting countries and is an essential pillar in its economy. For this reason, the present investigation had as objective the evaluation of the use of gibberellic acid (AG3) in the phenological cycle of the Delphinium elatum crop after the pinch, in three varieties (blue bird, summer skies and galahad). For this, a randomized design was used as well as with two doses of gibberellic acid (AG3) 0.5cc/l and 0.75cc/L for the treatments. In the same way, the phenological state of the crop will be determined from the pinch and variables such as length, diameter of the stem, days of sprouting, length and days of inflorescence appearance and the production achieved will be evaluated. Among the results, the increase in the length of the stem, stem diameter, length of the inflorescence and the decrease in the days of sprouting are evident. In the same way, it was possible to observe that the dose of 0.75cc/L applied to the varieties improved crop production compared to the dose of 0.5cc/L. And by counting the stems harvested for each variety and treatment, a higher production of the Delphinium elatum summer skies crop variety is assumed, where the results show that the application of 0.75cc/L N-large doses of the product containing 65.10g/l.
