| description | The Andean blueberry (Vaccinium meridionale Swartz) is a promising fruit crop that has gained importance in the market because of its nutritional and medicinal properties; however, there are few studies on the optimal conditions for growth and production. In this study, the vegetative growth of Andean blueberry plants was evaluated for 200 days in three sites at different altitudes in the Department of Cundinamarca (Colombia): municipality of San Francisco (1,885 m a.s.l.), Bogota (Universidad Nacional de Colombia - UNAL, 2,556 m a.s.l.), and Cruz Verde páramo (3,298 m a.s.l.). For the evaluation, 2-year-old plants were used that were propagated in vitro. The experiment had a repeated measures design, with 3 treatments (locations) and 5 data collection times, with destructive measurements at the beginning and at the end of the trial. Data for leaf area per plant, plant height, stem width, number of primary branches, branch length, and chlorophyll contents in leaves were taken. The tallest plants, with the largest leaf area and most dry matter, were found at the UNAL (2,556 m a.s.l.). Morphological and physiological variations were observed in response to each of the environments, with correlations between the growth variables and the environmental variables. The highest percentage distribution of dry matter in leaves was in the plants from the Cruz Verde páramo (3,298 m a.s.l.), while the percentage distribution of dry weight in the stem was higher in the plants from San Francisco (1,885 m a.s.l.). The percentage distribution of root dry weight was greater in the plants from San Francisco than those from other locations. The results indicated that the Andean blueberry plants had the most suitable conditions for vegetative growth at altitudes close to 2,556 m a.s.l. |

El agraz (Vaccinium meridionale) es un frutal promisorio que ha adquirido importancia en el mercado por sus propiedades nutricionales y medicinales, sin embargo, existen pocos estudios acerca de las condiciones óptimas para su crecimiento y producción. En este trabajo se evaluó el crecimiento vegetativo de plantas de agraz durante 200 días en el departamento de Cundinamarca (Colombia), donde se seleccionaron tres sitios con altitudes diferentes: municipio de San Francisco (1.885 msnm), Universidad Nacional de Colombia – UNAL (2.556 msnm) y páramo Cruz Verde (3.298 msnm). Para la evaluación se utilizaron plantas de 2 años de edad propagadas in vitro. El experimento tuvo un diseño de medidas repetidas, con 3 tratamientos (localidades) y 5 muestreos de toma de datos, con mediciones destructivas al inicio y al final del ensayo. Se tomaron datos de área foliar por planta, grosor del tallo, altura de la planta, número y longitud de ramas primarias y el contenido de clorofila en las hojas. Las plantas más altas con mayor área foliar y materia seca se presentaron en la UNAL (2.556 msnm). Se observaron variaciones morfológicas y fisiológicas en respuesta a cada uno de los ambientes, presentando correlaciones entre las variables de crecimiento y las variables ambientales. La distribución de materia seca en hojas presentó un mayor porcentaje en las plantas del páramo (3.298 msnm), mientras que la distribución de peso seco de tallo fue mayor en las plantas de San Francisco (1.885 msnm). La distribución de peso seco de raíces fue mayor en las plantas de San Francisco con respecto a las de otras localidades. Los resultados indicaron que las plantas de agraz en altitudes cercanas a los 2.556 msnm, posean las condiciones más adecuadas para su crecimiento vegetativo.
