| description | Champa (Campomanesia lineatifolia R. & P.), is a fruit species of the Mirtaceae family with high trading potential due to the palatability of its fruits. Its spread by seeds has difficulties related to a low germination percentage and a long time to complete this stage. Taking into account that the effect of the light on champa seeds is unknown, the objective of this study was to determine the effect of different light treatments on the germination of champa seeds under laboratory conditions. The plant material was collected in Miraflores, a municipality of Boyacá state in Colombia. An experiment was carried out in a completely randomized design with 4 treatments corresponding to different light conditions, for which the seeds were sown in Petri dishes that were covered with aluminum foil (dark), red cellophane paper, blue cellophane paper and one group was not covered (control). Each treatment had 4 repetitions, the experimental unit was composed of a Petri dish with 35 seeds. Germination and viability (tetrazolium test) parameters were determined. The maximum germination percentage (57.85%) and the highest germination speed (0.39 germinated seeds/d) were obtained with the red light treatment, the opposite response was obtained with the seeds in the dark. The freshly harvested seeds presented 93.74% viability. The seeds that did not germinate had a representative percentage of viable seeds (between 15 and 20%). These results allow us to conclude that C. lineatifolia has a positive photoblastism behavior and presents dormancy conditions, possibly physiological dormancy.

La champa (Campomanesia lineatifolia R. & P.) es una especie frutal de la familia Myrtaceae, con gran potencial de comercialización por el agradable sabor de sus frutos. Su propagación por semillas presenta dificultades asociadas a un bajo porcentaje de germinación y un tiempo prolongado para culminar esta etapa. Como se desconoce el efecto que pueda generar la luz en las semillas de champa, el objetivo de este estudio fue determinar el efecto de diferentes tratamientos de luz sobre la germinación de semillas champa en condiciones de laboratorio. El material vegetal fue recolectado en el municipio de Miraflores, Boyacá, Colombia. Se hizo un experimento en un diseño completamente al azar con cuatro tratamientos correspondientes a diferentes condiciones de luz: las semillas fueron sembradas en cajas Petri que se cubrieron con papel aluminio (oscuridad), papel celofán rojo, papel celofán azul y un grupo testigo sin cubierta. Cada tratamiento tuvo cuatro repeticiones, la unidad experimental estuvo compuesta de una caja Petri con 35 semillas. Se determinaron parámetros de germinación y de viabilidad a través del test de tetrazolio. Máximo porcentaje de germinación (57,85 %) y mayor velocidad de germinación (0,39 semillas germinadas/d) con el tratamiento de luz roja; respuesta contraria con las semillas en oscuridad. Las semillas recién cosechadas presentaron 93,74 % de viabilidad. Las que no germinaron obtuvieron un porcentaje representativo de semillas viables (entre el 15 y 20 %). Estos resultados permiten concluir que C. lineatifolia tiene comportamiento de fotoblastismo positivo y presenta condiciones de latencia, posiblemente fisiológica.
