Aplicación de láminas de riego y utilización de giberelina en la producción de limón sutil [Citrus aurantifolia (Christm.) Swingle]

Abstract

Currently, lemon production is often threatened by the effects of climate change, with drought being the main problem, which is why producers are forced to meet the water demands of the crop, however, it is of the utmost importance. seek to save water without affecting the productivity of the crop, therefore, a moderate reduction of water is convenient, with 50% of the ETC. Gibberellins also play an important role as a regulator of plant growth and especially in fruit set, they have been involved in different physiological processes and improve the production and quality of the fruit, being considered a highly profitable alternative for the producer. The purpose of this research was to determine irrigation sheets and the application of gibberellins in the production of subtle lemon (Citrus aurantifolia Swingle). The trial was carried out in the Santa Ana Canton, Manabí province. Three irrigation sheets (51,72 m3 h-1; 46,55 m3 h-1; 38,79 m3 h-1) and two doses of gibberellic acid (80 ppm and 200 ppm) were applied to the subtle lemon crop. Among the yield variables, fruit growth, fruit weight, equatorial and polar diameter were evaluated, while the internal quality variables of the fruit that were evaluated were pulp weight, shell weight, juice content, number of seeds and fruit content. of soluble solids “brix degrees”. As results, it was obtained that the highest growth rates of the fruit (45,40 g) and yields (49,47 kg/tree) were reached with water volumes of 51,72 m3 h-1 corresponding to sheet. While that the doses of GA3 did not differ significantly in any of the variables of growth and internal quality of the fruit. Therefore, it is concluded that the effect of the irrigation sheets was more present than the hormonal effect.
