Alternate bearing and phenology of ‘Valencia’ orange (Citrus sinensis [L.] Osbeck) in the lowland wet tropics of Colombia
In tropical conditions near the equatorial, precipitation is the main climatic factor that influences the growth and development of citrus plants. In a ‘Valencia’ orange orchard planted with 11-year-old trees located in the higher portion of the foothills of Corpoica, La Libertad Research Center in Villavicencio, Meta, Colombia, we recorded tree production data between the years 2008-2010. Information on the phenology of ten marked trees was gathered fortnightly from four cardinal directions using the methodology of Garrán et al. (1993) during the years 2009 and 2010. For this same period, the water balance was calculated for this orchard. The data were analyzed with descriptive statistics for most variables, and a mean-comparison test was carried out for the phenology observed at the cardinal points and for the correlation between annual precipitation and phenology. There was a positive correlation of 0.6 between rainfall and vegetative growth in 2009 and a negative correlation of -0.18 in 2010. There were no differences in phenology at the cardinal points. In 2008, the plants produced 168.8 kg/plant, causing the plants to present a strong vegetative growth and low yield (42.4 kg/tree) in 2009, whereas in 2010 there was an increase in the number of reproductive shoots, a decrease in the number of vegetative shoots and the harvest was 147.8 kg/tree. An alternation in the use of carbohydrates was observed between plant yield and vegetative growth.

In a ‘Valencia’ orange orchard planted with 11-year-old trees located in the higher portion of the foothills of Corpoica, La Libertad Research Center in Villavicencio, Meta, Colombia, we recorded tree production data between the years 2008-2010. Information on the phenology of ten marked trees was gathered fortnightly from four cardinal directions using the methodology of Garrán et al. (1993) during the years 2009 and 2010.

There was a positive correlation of 0.6 between rainfall and vegetative growth in 2009 and a negative correlation of -0.18 in 2010. There were no differences in phenology at the cardinal points. In 2008, the plants produced 168.8 kg/plant, causing the plants to present a strong vegetative growth and low yield (42.4 kg/tree) in 2009, whereas in 2010 there was an increase in the number of reproductive shoots, a decrease in the number of vegetative shoots and the harvest was 147.8 kg/tree.

En condiciones tropicales cerca de la línea ecuatorial, la precipitación es el principal factor climático que influye sobre el crecimiento y desarrollo de las plantas de cítricos. En un cultivo de naranja ‘Valencia’ de 11 años de edad ubicado en suelos de la terraza alta del piedemonte llanero en Corpoica, Centro de Investigación La Libertad, en Villavicencio, Meta, Colombia, se llevaron los registros de producción por árbol en los años 2008 a 2010. A diez árboles marcados se le tomó información quincenal de la fenología de la planta en los cuatro puntos cardinales utilizando la metodología de Garrán et al. (1993) durante los años 2009 y 2010. Para estos mismos años se calculó el balance hídrico para el cultivo. La información se analizó con estadística descriptiva para la mayoría de las variables, prueba de comparación de medias para la fenología por puntos cardinales y correlación entre la precipitación anual y la fenología. Se presentó una correlación positiva de 0,6 entre precipitación y crecimiento vegetativo en el año 2009 y negativa de -0,18 en el año 2010. No se presentaron diferencias en la fenología por puntos cardinales. En el año 2008 las plantas obtuvieron 168,8 kg/planta, lo que ocasionó que en el año 2009 estas presentaran una fuerte brotación vegetativa y baja cosecha (42,4 kg/árbol); mientras que en el año 2010 aumentaron los brotes reproductivos, disminuyeron los brotes vegetativos y la cosecha fue de 147,8 kg/árbol. Se presentó una alternancia en el uso de carbohidratos entre el rendimiento de la planta y la brotación vegetativa. 2019-08-09T19:29:58Z 2019-08-09T19:29:58Z 2013 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion http://revistacta.agrosavia.co/index.php/revista/article/view/248 10.21930/rcta.vol13_num2_art:248 http://hdl.handle.net/20.500.12324/35130 reponame:Biblioteca Digital Agropecuaria de Colombia repourl:https://repository.agrosavia.co instname:Corporación colombiana de investigación agropecuaria AGROSAVIA spa http://revistacta.agrosavia.co/index.php/revista/article/view/248/251 application/pdf Corporación Colombiana de Investigación Agropecuaria (Agrosavia) Ciencia y Tecnología Agropecuaria; Vol 13 No 2 (2012); 136-144 Ciencia y Tecnología Agropecuaria; Vol. 13 Núm. 2 (2012); 136-144 revista Corpoica Ciência e Tecnologia Agropecuária; v. 13 n. 2 (2012); 136-144 2500-5308 0122-8706 10.21930/rcta.vol13-num2 |
