| description | Croton guatemalensis is a threatened and multipurpose species in communities of southeastern Mexico and Central America. For the first time, its reproductive phenology and its relationship with environmental variables present in four different natural protected areas of the Zoque Tropical Forest Biological Corridor was determined. Throughout a year the flowering and fructification of the species was monitored, the local environmental variables were recorded and fruits and seeds were collected to determine, under a random design, the germination of the seeds and the growth of seedlings in the laboratory and in nursery respectively. In all cases, flowering was presented from July to April, while fructification occurred from March to September, coinciding with the months where the rains diminish considerably. In terms of seed germination, it presented a statistically significant difference between seeds from the four protected areas. The most contrasting results were presented between La Pera and Area Villa de Allende (98% ± 3.84% and 6% ± 3.84% respectively). According to the generalized linear model, soil porosity was the only variable that influenced the germination of the species (the higher the porosity, the higher the percentage of final germination, t = 2.237, P = 0.0503). Because this is the first study on the ecophysiology of C. guatemalensis in southern Mexico, the importance of it becomes relevant when providing fundamental reproductive information for the generation of strategies for conservation, restoration and forest management of the species. |

Croton guatemalensis es una especie amenazada y multipropósito de comunidades del sureste de México y América Central. Por primera vez, se determinó su fenología reproductiva y su relación con las variables ambientales presentes en cuatro áreas naturales protegidas del Corredor Biológico Selva Zoque. A lo largo de un año, se monitoreó la floración y fructificación de la especie, se registraron las variables ambientales locales y se recolectaron frutos y semillas para determinar, bajo un diseño aleatorio, la germinación de las semillas y el crecimiento de las plántulas en el laboratorio y en el vivero respectivamente. En todos los casos, la floración se presentó de julio a abril, mientras que la fructificación ocurrió de marzo a septiembre, coincidiendo con los meses en que las lluvias disminuyen considerablemente. En términos de germinación de semillas, se presentó una diferencia estadísticamente significativa entre las semillas de las cuatro áreas naturales protegidas. Los resultados más contrastantes se presentaron entre La Pera y Área Villa de Allende (98% ± 3.84% y 6% ± 3.84% respectivamente). Según el modelo lineal generalizado, la porosidad del suelo fue la única variable que influyó en la germinación de la especie (a mayor porosidad, mayor porcentaje de germinación final, t = 2.237, P = 0.0503). Debido a que este es el primer estudio sobre la ecofisiología de C. guatemalensis en el sur de México, el estudio se vuelve relevante al proporcionar información reproductiva fundamental para la generación de estrategias de conservación, restauración y manejo forestal de la especie.
