| description | In Colombia, the blackberry is an important perennial crop for the economic sustainable development of medium and smallholder farmers. Pruning is essential for this crop and aims to renew the productive, fruit bearing branches and normalize the sink-source relationships of photoassimilates. The establishment of physiological indices and growth curves for blackberry crops with different pruning practices will develop proposals for the agricultural handling of this species. In this study, two-year-old blackberry crops were used with a T-trellis; 48 canes were grouped into three pruning treatments; a) control: without pruning; b) short pruning: canes with a 1.6 m length; and c) long pruning; canes with a 2.6 m length. The length of the canes, and the number of leaves and panicles were registered over time, in terms of days after sprouting. The curves and rates of growth were established with a functional analysis. The logistic model was ideal for expressing the growth of the plants. The maximum length of the canes was seen at 231 days after sprouting: 535 cm. The relative growth rate of the canes decreased gradually over time. The values of the absolute growth rate of the canes as well as the number of leaves and panicles decreased over time too. The maximum number of leaves was seen from 55 to 231 days after sprouting; the flowering in the plants in the pruned treatments started at 126 days after sprouting. The average number of inflorescences was 18 in the shrubs without pruning, 10 with the short pruning and 21 with the long pruning. The results showed that pruning is a determinant factor in the physiological and productive development of blackberry shrubs and that the long pruning, with a 2.6 m length, was the best pruning alternative. |

El cultivo de mora en Colombia es un renglón importante para el desarrollo económico de medianos y pequeños productores. Las actividades de poda son labores indispensables en este cultivo y tienen el propósito de renovar las ramas productivas y mejorar la relación entre la oferta y demanda de fotoasimilados. En el presente ensayo se utilizaron plantas de dos años de edad, tutoradas en T; se marcaron 48 tallos bajo diferentes sistemas de poda (testigo: sin podar; poda corta: tallo a 1,6 m de longitud; poda larga: tallo a 2,6 m de longitud), se midió la longitud de los tallos, y se registró el número de hojas y de panículas aparecidas a lo largo del tiempo, se graficó el comportamiento de las variables respecto a los días después de brotación (ddb). Se establecieron las curvas y las tasas de crecimiento mediante análisis funcional. Como resultado se obtuvo que los modelos logísticos fueron de mejor ajuste para la descripción del crecimiento de esta especie, la máxima longitud del tallo se presentó a los 231 ddb con 535 cm, la tasa relativa de crecimiento (TRC) del tallo disminuyó gradualmente, la tasa absoluta de crecimiento (TAC) del tallo así como el número de hojas y panículas disminuyeron con el tiempo. El número máximo de hojas fue de 55 a los 231 ddb; la floración en todos los sistemas de poda inició a los 126 ddb aproximadamente; el número de inflorescencias en promedio fue de 18 en plantas sin poda, mientras que con poda corta tuvo un valor de 10, y de 21 con poda larga. Los resultados mostraron que la poda es un factor determinante en el desarrollo fisiológico y productivo en esta especie de mora.
