Evaluación de tres métodos de polinización artificial en el cultivo de chirimoya (Annona cherimola) en el cantón Patate

Abstract

This research was carried out in the Patate canton in order to evaluate the different methods of artificial pollination in the cultivation of cherimoya (Annona cherimola) in the Patate canton, with the purpose of generating quality products, thus improving the economy of the farmers. For the present research, an experimental design of completely randomized blocks with three treatments and three replications was used. In addition, an analysis of variance (ADEVA) was performed and then the data were examined by means of Tukey tests at 5% of the treatments that presented statistical significance. The positive results obtained for the variables under study in the case of the variables fertilization percentage, days of appearance of the first fruits and number of fruit set, T2 was the best treatment using the insufflator technique, with an average of 94.29%, 27 days and 2.77 fruit set per branch, followed by treatments T1 and T3, unlike the control, which showed the lowest efficiency in terms of the variables analyzed. However, the size of fruit set in T3 by hand-pollination technique showed an average of 23.76 mm in polar diameter and 24.24 mm in equatorial diameter, followed by T1 and T2 with 21.59 mm and 20.26 mm in polar diameter; however, in polar diameter, the treatments did not show significant differences.
