Effect of the application of the hormone Giberelin on the growth and development of the cultivation of Maracuyá (Passiflora edulis f. flavicarpa) established on the sidewalk Fatima of the municipality of La Plata, Huila

Abstract

The cultivation of passion fruit (P. edulis) is part of an important production system of Huila, which is why in this project it was proposed to evaluate the effect of the application of the Giberelin hormone on the growth and development of the cultivation of passion fruit established in the sidewalk Fatima of the municipality of La Plata (Huila); the experimental design consisted of two treatments, differentiated as follows: one witness group (T1) and another experimental group (T2) to which a dosage of 0.075 grams of giberelic acid (ACIGIB 10 SP®) was applied after the crop cleaning pruning. In the field, variables such as: number of flowers and fruits were tracked, and in laboratory physical-chemical parameters were measured such as: fruit weight (gr), Solid soluble total (Brix), titratable acidity (%) and pH; all of them with a randomly chosen sample size (n=10). With the results obtained, a simple Anova was performed to determine whether each of the proposed treatments (referred to as a factor) had a significant effect on the response variables (fruit weight, SST, AT and pH), with a confidence level of 95%. These analyses were performed using the Statgraphics Centurion XVI program. The results showed that for the variables: Flower and fruit number, SST and pH there were no significant differences. In the meantime, for pulp weight variables and acidity percentage, if significant differences were found, obtaining that in T1 the pulp weight was 102.5g versus T2 weighing 134.94 g, and in percentage of acidity T1 (3.41%) and T2 (4.05%) you can see a slight advantage of those plants that were treated with the hormone, a key aspect for the quality control of the fruits for later marketing.
