| description | Climate factors affect the phenological behavior of Japanese plum (Prunus salicina Lindl.) cultivation in tropical elevation. Thermal time is more precise than chronological time for the cultivation labor program and for the estimation of crop phenological events. The objective of this study was to determine the base temperature (Tb) and thermal time for the development of the 'Horvin' plum fruit, estimating the Tb for the reproductive phenological phase of the plum. Twenty trees, consisting of ten trees per rowat two different elevations of 2,195 and 2,567 m a.s.l. (meters above sea level), in the municipality of Nuevo Colon (Colombia), were marked by locality. The appearance of each phenological stage was recorded from floral bud to harvest, estimating Tb with the minimum coefficient method of variation in function of growing degree day (GDD). The results show Tb for the phenological stages floral-anthesis with 2.84°C; anthesis-fruits set, 3.05 °C, and fruit set-harvest, 1.76°C. Therefore, this variety should be grown where there is a minimum temperature of 3.05°C during the reproductive phase. In addition, the results show that an average of 1,243.17 and 1,172.12 GDD is required to go from fruit set to fruit harvest at elevations 2,195 and 2,567 m a.s.l., respectively. |

Los factores climáticos afectan el comportamiento fenológico del cultivo de ciruelo japonés (Prunus salicina Lindl.) en la altitud tropical. El tiempo térmico es más preciso que el tiempo cronológico para la programación de labores culturales y para la estimación de eventos fenológicos del cultivo. El objetivo de este estudio fue determinar la temperatura base (Tb) y el tiempo térmico para el desarrollo del fruto de ciruela 'Horvin', estimando la Tb para la fase fenológica reproductiva de la ciruela. Se marcaron por localidad veinte árboles, diez árboles por surco, en dos elevaciones diferentes: 2.195 y 2.567 msnm (metros sobre el nivel del mar), en el municipio de Nuevo Colón (Boyacá, Colombia). La aparición de cada estado fenológico se registró desde el botón floral hasta la cosecha, estimando la Tb con el método de coeficiente mínimo de variación en función de los grados día de crecimiento (GDC). Los resultados muestran las Tb para los estados fenológicos botón floral-antesis con 2,84°C; antesis-cuajado de fruto 3,05°C y 1,76°C cuajado de fruto-cosecha. Por lo tanto, esta variedad debe cultivarse donde haya una temperatura mínima de 3,05°C durante la fase reproductiva. Además, los resultados revelan que se requiere un promedio de 1.243,17 y 1.172,12 GDC, para pasar del cuajado a la cosecha del fruto en las elevaciones 2.195 y 2.567 msnm, respectivamente.
