Efecto de auxinas en el cultivo de sandía (Citrullus lanatus), para promover la reducción de semillas en el fruto, en la parroquia Lago San Pedro, cantón Joya de los Sachas

Abstract

The lack of studies in Joya of Sachas canton on production alternatives provided by auxin phytohormones in watermelon cultivation has repercussions on range of knowledge and economic profitability of farmers in area. Therefore, the objective this research was to assess the effect of auxins in the watermelon crop (Citrullus lanatus), through an analysis of morphometric variables (fruit weight, fruit diameter, fruit length and number seeds), to promote the fruit seed reduction, in the property of Mr. Segundo Elías Astudillo Calle, in Lake San Pedro Parish, Joya of Sachas Canton. The methodology had a quantitative approach, study design was adjusted to an experimental type of research, through which an association of variables was established and was proposed in three treatments with auxins; T1 (1 cc/l), T2 (2 cc/l) and control, with three replicates. The application of the plant hormone was made by spraying in aerosol form. The methodology showed statistically significant differences between treatments, T2 treatment being superior in fruit terms, with average values 15.32 kg weight; 24.63 cm diameter; 41.40 cm length; and 548.10 seeds. Compared T1 treatment and control. Thus, it is concluded that treatment with the highest dose (T2) produced a greater reduction in the number of seeds, in addition, it maximized the proportions in weight and size of the fruit.
