| description | Biostimulants can potentially improve plant growth and development, modifying physiological processes. This study evaluated the effect of four biostimulants on the growth of ‘Hartón’ plantain plants and the leaf gas exchange during the vegetative phase. This experiment was developed on a plantain farm’s nursery in Fuente de Oro (Colombia) with a randomized complete block design with four replicates. The treatments were the biostimulants: Bactox WP®: Bacillus subtilis (Bs); Baliente®: Bacillus amyloliquefaciens (Ba); Tierra Diatomeas®: silicon dioxide (Si); Re-Leaf®: salicylic acid (SA) and the control (water). All products had a positive effect on the accumulation of total dry matter (DM) (between 58.4 and 21.9%) and on the photosynthetic activity (a maximum of 110 and 24.3% in first and second evaluation), as compared to the control, while no differences were found (P>0.05) for the foliar emission rate and chlorophyll content between the treatments. The plants treated with Bs had the greatest DM accumulation at the end of the study and a constant, high photosynthetic activity. All the while Bs, Ba and Si managed to stimulate greater early photosynthetic activity. According to the results, the use of these biostimulants during the vegetative phase had an effect on the physiological processes that enhance DM accumulation in plantain plants, which could be potentially useful for the transplanting stage and increase the reserves used during their establishment and development in the field. |

Los bioestimulantes son productos que potencialmente pueden mejorar el crecimiento y desarrollo de las plantas al modificar procesos fisiológicos. En este estudio se evaluó la influencia de cuatro bioestimulantes en el crecimiento de plantas de plátano ‘Hartón’ e intercambio de gases en un periodo de la fase vegetativa. El experimento se desarrolló en el vivero de una finca productora de plátano en Fuente de Oro (Colombia), en un diseño de bloques completos al azar generalizados con cuatro repeticiones. Los tratamientos correspondieron a los bioestimulantes Bactox WP®: Bacillus subtilis (Bs); Baliente®: Bacillus amyloliquefaciens (Ba); Tierras de diatomeas®: dióxido de silicio (Si); Re-Leaf®: ácido salicílico (As) y el control (agua). Todos los productos mostraron tener un efecto positivo en la acumulación de materia seca (MS) total (entre 58,4 y 21,9%) y en la actividad fotosintética (en un máximo de 110 y 24,3% en primera y segunda evaluación) respecto al control, mientras que en ritmo de emisión foliar y contenido de clorofila no se encontraron diferencias (P>0,05) entre tratamientos. Plantas tratadas con Bs tuvieron la mayor acumulación de MS al finalizar el estudio y una alta actividad fotosintética constante. Mientras que Bs, Ba y Si lograron estimular una mayor actividad fotosintética temprana. De acuerdo con los resultados el uso de estos bioestimulantes durante esta fase vegetativa tiene efecto sobre procesos fisiológicos que mejoran la acumulación de MS en plantas de plátano, lo que podría capacitarlo para enfrentar la etapa de trasplante y aumentar las reservas para ser utilizadas durante su establecimiento y desarrollo en campo.
