Influence of water deficit on growth and development of fruits valencia orange (Citrus sinensis Osbeck) in the piedmont of Meta department, Colombia
In Colombia the area planted with citrus is marginal when compared to the potential area for cultivation,due to factors such as water deficit, nutrition and efficiency of fruit formation.The aim of this study was to evaluate the effect of water deficit by controlled application of water throughsoil profile in orange crop var.Valencia (Citrus sinensis Osbeck) in the foothills Meta department, Colombia.The irrigation treatments (T) were: T1 = 100% of crop evapotranspiration (ETc); T2 = 50% ETc;T3 = control = 0% ETc. Irrigation was applied from the beginning of flowering in February to fruit formationin April 2011. The experimental design was randomized complete blocks with three replicatesper treatment. The variables evaluated were: soil moisture (θg), plant water status (Ψtallo), phenology,budding, flowering, formation, growth and fruit quality. The trees in the T1 had a higher number andsize of fruit, but found no differences (P> 0.05) in yield and quality compared to the control, the θg andΨtallo were different (P

El objetivo del presente estudio fue evaluar el efecto del déficit hídrico mediante la aplicación controlada de láminas de riego en el cultivo de naranja Valencia (Citrus sinensis Osbeck) en el piedemonte del Meta (departamento del Meta, Colombia). Los tratamientos (T) de riego fueron: T1 = 100% de la evapotranspiración del cultivo (ETc); T2 = 50% ETc; T3 = testigo = 0% ETc. El riego se aplicó desde el inicio de la floración en febrero hasta la formación del fruto en abril de 2011. El diseño experimental fue bloques completamente al azar con tres repeticiones por tratamiento. Las variables evaluadas fueron: humedad del suelo (θg), estado hídrico de la planta (Ψtallo), fenología, brotación, floración, formación, crecimiento y calidad del fruto. Los árboles en el T1 presentaron un mayor número y tamaño de fruto, pero no se encontraron diferencias (P > 0.05) en producción y calidad respecto al testigo; la θg y el Ψ tallo fueron diferentes (P < 0.05) entre tratamientos y el testigo mostró los menores valores, 13.82% y -2.5 MPa, lo cual indica un estrés moderado.
