| description | The expansion of 'Hass' avocado areas in the Colombian territory added to the problems associated with production, requires advancing the research efforts in order to elucidate the behavior of avocado in the conditions of the Andean tropics of Colombia. The aim of this study was to determine the effect of photosynthetically active radiation (PAR), ambient temperature, relative humidity and cardinal position of the inflorescences on the retention and final growth of 'Hass' avocado fruits in two contrasting zones of the Andean tropics of Colombia. The study was conducted in two commercial orchards located in different altitudinal zones in the department of Caldas, Colombia, Villamaría at 2,400 m above sea level (m a.s.l.) (5º01'05'' N) classified as a humid cold climate and Aranzazu at 1,900 m a.s.l. (5º18'40'' N) with semi-humid temperate climate. Evaluations were conducted on four five-year-old 'Hass' avocado trees per orchard. Monitoring was carried out on number of inflorescences that developed in each quadrant was determined and that thus learned the effect of PAR, temperature and humidity on floral development and identified the most reproductively successful quadrant of the trees in the two zones. Initial fruit set and fruit retention over time were quantified at each cardinal point of the tree. A completely randomized experimental design and Tukey's comparison of means was used. Significant differences were found PAR incidence, ambient temperature, air humidity, fruit weight and diameter according to cardinal location on the tree and locality, epidermal roughness of the fruit was higher in the lower altitude zone. The location of the different quadrants and the incidence of environmental factors it had an effect in fruit set, the final retention, size and quality of fruit at two different altitude and climatic zones of the Andean tropics of Colombia. The highest fruit retention was obtained at 1,900 m a.s.l. in the northern and western quadrants, while fruit weight and diameter were highest at 2,400 m a.s.l. |

La expansión de las áreas de aguacate 'Hass' en el territorio colombiano sumado a los problemas asociados a la producción, requiere avanzar en los esfuerzos de investigación con el fin de dilucidar el comportamiento del aguacate en las condiciones del trópico andino de Colombia. El objetivo de este estudio fue determinar el efecto de la radiación fotosintéticamente activa (RFA), temperatura ambiente, humedad relativa y posición cardinal de las inflorescencias sobre la retención y crecimiento final de frutos de aguacate 'Hass' en dos zonas contrastantes del trópico andino de Colombia. El estudio se realizó en dos huertas comerciales ubicadas en diferentes pisos altitudinales en el departamento de Caldas, Colombia, Villamaría a 2.400 m sobre el nivel del mar (msnm) (5º01'05'' N) clasificado como clima frío húmedo y Aranzazu a 1.900 msnm (5º18'40'' N) con clima templado semihúmedo. Se realizaron evaluaciones en cuatro árboles de aguacate 'Hass' de cinco años por huerto. Se realizó un seguimiento del número de inflorescencias que se desarrollaron en cada cuadrante y así se conoció el efecto del RFA, la temperatura y la humedad en el desarrollo floral y se identificó el cuadrante más exitoso reproductivamente de los árboles en las dos zonas. El cuajado inicial de frutos y la retención de frutos a lo largo del tiempo se cuantificaron en cada punto cardinal del árbol. Se utilizó un diseño experimental completamente al azar y comparación de medias de Tukey. Se encontraron diferencias significativas en la incidencia de RFA, temperatura ambiente, humedad del aire, peso y diámetro del fruto según el punto cardinal del árbol y la localidad, siendo mayor la rugosidad epidérmica del fruto en la zona de menor altitud. La ubicación de los diferentes cuadrantes y la incidencia de los factores ambientales tuvo efecto en el cuajado, la retención final, el tamaño y la calidad del fruto en las dos zonas altitudinales y climáticas diferentes del trópico andino de Colombia. La mayor retención de fruto se obtuvo a los 1,950 msnm en los cuadrantes norte y oeste, mientras el peso y el diámetro de los frutos tuvo valores más altos a los 2,400 msnm.
