description Previous experiences demonstrated the efficiency of the floating system for growing lisianthus (Eustoma grandiflorum L.) seedlings. Using this system, root growth usually expands through the plug cell drainage hole into the solution originating some difficulties at transplant. Pruning roots could facilitate transplant as seedlings could be taken out of the tray more easily. However, root damages at the cutting point are a possible access for pathogens. The use of Cu(OH)2 in the nutrient solution as a chemical pruning method was evaluated. Lisianthus seeds were sown in floating trays and placed in nutrient solutions containing 0, 12, 23, 46, 92 and 138 g L-1 Cu(OH)2. After 30, 40, 47 and 54 days, fresh and dry weights of seedlings were recorded. When seedlings reached four expanded leaves they were transplanted to soil in a greenhouse. At flowering, shoots were harvested to evaluate flower stem quality. Total root and shoot fresh and dry weights were higher for seedlings cultivated with 0.023 or higher doses of Cu(OH)2. However, roots mass inside the tray cell were higher in all treatments compared to the control. The use of Cu(OH)2 during plug stage improved transplant size and no effect on further plant growth and development was observed

La poda mecánica de raíces podría permitir que los plantines sean extraídos de la bandeja con mayor facilidad. Sin embargo, daños en las raíces debido al corte podrían ser vías de ingreso de patógenos. Semillas de lisianthus (Eustoma grandiflorum L.) fueron sembradas en bandejas flotantes utilizando soluciones nutritivas con 0, 12, 23, 46, 92 y 138 mg L-1 de Cu(OH)2 para evaluar su uso como agente de poda química. Luego de 30, 40, 47 y 54 días, se registró el peso fresco y seco de los plantines. Posteriormente se trasplantaron a un cantero dentro de un invernáculo y en floración se cosecharon para determinar la calidad de la vara. El peso fresco y seco de los plantines fue mayor al control en los tratamientos con 23 mg L-1 o mayores concentraciones de Cu(OH)2. Sin embargo, la masa de raíces dentro de la celda fue mayor en todos los tratamientos respecto del control. El uso de Cu(OH)2 durante la producción de plantines mejoró el tamaño del plantín y no tuvo efecto en el crecimiento y desarrollo posterior del cultivo.
