Concentración de fructosa en frutos de toronja (Citrus paradisi Macf.) en desarrollo

Abstract

El estudio se realizó en el ciclo 2014-2015, en una huerta de toronja (Citrus paradisi Macf.) variedad Rio Red, del Municipio de General Terán, N.L. México. El objetivo fue evaluar la concentración de fructosa en frutos de toronja en desarrollo procedentes de árboles de producción elevada («on») y producción escasa («off»), en un ciclo de producción en respuesta a la aplicación de ácido giberélico (Acigib 10% de GA3 , 25 ppm), urea foliar (1 kg 100 L-1) y anillado de ramas. La fructosa fue cuantificada en frutos de toronja a los 30, 60 y 90 dda (días después de antesis). El análisis de fructosa se realizó mediante Cromatografía Líquida de Alta Presión (HPLC). A los 30 dda, las aplicaciones de urea foliar y GA3 en árboles «on» resultaron en los valores más altos en la concentración de fructosa en frutos. A los 60 dda no se presentaron diferencias estadísticas entre los tratamientos. A los 90 dda los frutos de árboles «on» con urea foliar y con anillado se comportaron estadísticamente diferentes al resto de los tratamientos, con menor concentración de fructosa. El comportamiento de la concentración de fructosa en frutos de toronja entre muestreos fue de un incremento en todos los tratamientos de árboles «on» y «off». Abstract This research was conducted during the production year 2014- 15 on a 18-year in a grapefruit (Citrus paradasi Macf.) grove, Rio Red variety in the municipality of General Teran, N.L. Mexico. The objective was to evaluate the concentration of fructose in small fruits from trees with a high production year («on») and others with a low production year («off») throughout the whole productive cycle, as a result of the application of gibberellic acid (Acigib 10% of GA3 , 25 ppm), foliar urea (1 kg 100 L-1) and girdling. Fructose was quantified in fruits of grapefruit at 30, 60 and 90 days after anthesis (DDA). Fructose analysis was done by High Pressure Liquid Chromatography (HPLC). According with the results, application of foliar urea and GA3 on trees «on» at 30 DDA, resulted in the highest values in the concentration of fructose in fruit. Treatments applied at 60 DDA resulted in not statistically differences for fructose concentration in fruits. Fruit fructose concentration from samples at 90 DDA showed statistical differences in trees «on» treated with foliar urea and girdling obtained the lowest concentration of fructose. The behavior of the concentration of fructose between samples was increased in all treatments of trees «on» and «off». Keywords: Girdling, carbohydrates, citrus, gibberellic acid, foliar urea.
