| description | Since the root system is responsible for water and nutrient absorption from the soil, the objective of this research was to determine the root activity of five-year old plants of common acid lime on ‘Common Lime’ rootstock using isotope 32P as a tracer. In Flandes, Tolima, Colombia (28ºC mean temperature, 68% relative humidity, 1.177 mm annual precipitation, and sandy-loam soil), the application of 32P on three soil depths (15, 30, and 45 cm) and distances from the stem (100, 150, and 200 cm) were evaluated. The isotopic solution was applied at a rate of 5 mL to the zone of the tree disc. The experimental unit was one tree, and a standard sampling technique was used for leaves, branches (stem), and fruits with a 15 day sampling interval and a total of six samples. The isotope activity in the samples was determined by a counter of liquid sparkle using the Cerenkov method. The highest root activity appeared in the first 15 cm and between 15-30 cm of soil depth, reaching values between 14.5 and 18%. The distance where the highest percentage of activity was found, lay at 100 to 150 cm from the stem. The structure of the plant, where the greatest detection of the isotope was achieved, was the leaf. This information indicates that, for five-year old trees of common acid lime, the most active roots are located in the first 30 cm of soil, and between 100 and 150 cm from the stem. Therefore, it is in this zone where fertilizers and water should be supplied and multiple cultures may not be located. |

Puesto que el sistema radical es responsable de la toma de agua y nutrientes desde el suelo, el objetivo de este trabajo fue determinar la actividad radical en plantas de lima ácida común (sobre el patrón Limón común), de cinco años de edad, mediante la utilización del isótopo 32P como trazador. En Flandes, Tolima (Colombia), a 28ºC temperatura y 68% HR, 1.177 mm precipitación/año, en un suelo franco arenoso, se evaluaron tres profundidades de aplicación del 32P 15, 30 y 45 cm y tres distancias desde el tronco 100, 150 y 200 cm. La solución isotópica se aplicó en dosis de 5 mL ubicados alrededor de la zona de plateo del árbol. La unidad experimental fue un árbol y se empleó una técnica de muestreo estándar para hoja, ramas (tallo) y frutos con un intervalo de muestreo de 15 días y un total de seis muestreos. La actividad del isótopo en las muestras se determinó por conteo en un contador de centelleo líquido por efecto Cerenkov. La mayor actividad de las raíces se presentó en los primeros 15 cm y entre 15-30 cm de profundidad, alcanzando valores entre 14,5 y 18%. La distancia a la cual se encontró el mayor porcentaje de actividad fue a 100 cm y hasta los 150 cm desde el tronco. La estructura de la planta donde se logró hacer mayor detección del isótopo fue la hoja. Esta información indica que para árboles de lima ácida común de cinco años las raíces más activas se ubican en los primeros 30 cm de profundidad y entre 100 y 150 cm de distancia desde el tronco, por lo tanto es en esta zona donde deben ubicarse los fertilizantes y el suministro de agua para el cultivo y no ubicar arreglos de cultivos múltiples.
