Evaluación del tipo y altura del anillado en el cultivo de rosa (Rosa sp) en la producción de brotes laterales

Abstract

The cultivation of rose (Rosa sp) in Ecuador represents an important contribution to the economy of farmers due to the adaptation that the crop has to the climatic and geographical characteristics of the areas in which it is cultivated. With the practice of ringing, it is a question of making a transversal cut in the bark without removing tissues with a suitable tool. In order to temporarily interrupt the passage of the elaborated sap and hormones towards the root system, this leads to an increase in new shoots, fruit set and fruits with a greater volume. The hypothesis raised was that at least one of the treatments carried out will have a positive effect on ringing in roses. The experimental design used was randomized complete blocks in a 3x3+1 factorial arrangement with three repetitions. The study factors used were ring height; C1 (base of the plant), C2 (5 cm), C3 (10 cm) and ring diameter; D1 (scratched), D2 (ringed at 0.5 cm), D3 (ringed at 1em). The data was analyzed using the Turkey test (p< 0.05) for the comparison of the means. The treatments were applied according to the cuts; striped, ringed to 0.5 cm in diameter, and ringed to 1 cm in diameter. This activity was carried out only at the beginning of the investigation. For data collection, it was collected from five plants of each treatment where data such as; initial stem diameter, final stem diameter, number of sprouted buds, shoot diameter and shoot length. The results obtained showed significant differences in each variable studied. In the stem diameter at 60 days, it could be observed that the best treatment was C1D2 with an average of 17.23 mm, while the control (T) showed 15.22 mm, becoming the smallest of all the treatments. treatments. . In the variable number of sprouted buds, the C1D2 treatment presented an average of 3 sprouts per plant, reaching a numerical difference over the other treatments. The shoot diameter variable showed that the C2D3 treatment was the best in the trial, presenting an average of 11.03 mm, but only with a numerical difference to the other treatments. In the shoot length variable, the best in the trial was the C1D3 treatment, presenting an average of 31.33 cm per plant.
