| description | Blackberry is an important species among small fruits that have gained prominence in recent years in family farming in Brazil's southern and southeastern regions. Due to the lack of efficient methods in vegetative propagation, there is a need for exogenous application of growth regulators to promote root development. Therefore, the objective of this study was to evaluate the effect of indole butyric acid (IBA) and paclobutrazol (PBZ) on the rooting of stem cuttings of blackberry cv. Tupy. The cuttings were prepared with a length of 10 cm and planted in 114 cm3 tubes containing medium-sized vermiculite as substrate and conducted in a greenhouse with intermittent misting. The treatments consisted of three concentrations of IBA (500; 1,000 and 2,000 mg L-1) and PBZ (100, 200, and 400 mg mL-1)in addition to the control treatment. A completely randomized experimental design was used in a 4×4 factorial scheme, with three replicates and 10 cuttings per experimental unit. After 120 days, the percentages of rooted cuttings, callus formation, alive, dead, and sprouted cuttings, shoot length, number, length, and fresh weight of roots were evaluated. The use of plant hormones did not have a favorable effect on the propagation of blackberry cv. Tupy through stem cuttings, with inhibition of rooting observed. |

La mora es una especie importante entre los frutos pequeños que han ganado protagonismo en los últimos años en la agricultura familiar del sur y sureste de Brasil. Debido a la falta de métodos eficientes en la propagación vegetativa, existe la necesidad de la aplicación exógena de reguladores del crecimiento para promover el desarrollo de las raíces. Por lo tanto, el objetivo de este estudio fue evaluar el efecto del ácido indolbutírico (AIB) y paclobutrazol (PBZ) en el enraizamiento de estacas de la mora negra cv. Tupi. Las estacas se prepararon con una longitud de 10 cm y se plantaron en tubetes de 114 cm3 que contenían vermiculita de tamaño mediano como sustrato y se llevaron a cabo en un invernadero con nebulización intermitente. Los tratamientos consistieron en tres concentraciones de AIB (500, 1.000 y 2.000 mg L-1) y PBZ (100, 200 y 400 mg mL-1), además del tratamiento control. Se utilizó un diseño experimental completamente al azar en esquema factorial 4×4, con tres repeticiones y 10 estacas por unidad experimental. Después de 120 días, se evaluaron los porcentajes de estacas enraizadas, formación de callos, estacas vivas, muertas y brotadas, longitud de brotes, número, longitud y peso fresco de raíces. El uso de hormonas vegetales no tuvo efecto favorable en la propagación de la mora negra cv. Tupy a través de estacas, observándose inhibición del enraizamiento.
