Background and Aims: Croton guatemalensis is a native species that is used locally and plays an important role in the traditional medicine of people of the rural comunities of the Zoque Forest, Chiapas, Mexico. Currently it is protected by the NOM-059-SEMARNAT-2010 under “Special Protection”. The ob...

| description | Background and Aims: Croton guatemalensis is a native species that is used locally and plays an important role in the traditional medicine of people of the rural comunities of the Zoque Forest, Chiapas, Mexico. Currently it is protected by the NOM-059-SEMARNAT-2010 under “Special Protection”. The objectives of this research were to evaluate the morphometry, viability, health and germination of seeds collected from wild populations in four Protected Natural Areas of the Zoque Forest, Chiapas; and generate basic information that will allow the development in the future local programs or projects of conservation, restoration and forest management of the species, in order to reduce the impact on wild populations.Methods: From November 2016 to October 2017, plant material was collected to corroborate the taxonomic identification of Croton guatemalensis, and fruits and seeds to determine, under a random design, the size (length × thickness), weight, percentage of viability, health and germination of the seeds. Due to the abnormality of the data, the comparison and determination of the statistical differences between areas was carried out by Kruskal-Wallis and Mann-Whitney analyses, in the software R 3.24.Key results: The results indicate that there are statistically significant differences between the four collection zones. The most contrasting results were present in the Area Subject to Ecological Conservation La Pera and Protected Forest Area Vedada Villa de Allende. In the first, the seeds had larger size (5.13±0.06 × 3.26±0.06 mm), high percentage of health, viability and final germination (98±2.16, 98±2.30, 98±3.84%, respectively), while in the second, the seeds were smaller (4.63±0.09 × 2.69±0.08 mm), they obtained 68±6.65% of health, 19±5.03% of viability and 6±3.84% of final germination.Conclusions: The present study provides reproductive information essential for the generation of strategies for conservation, restoration and forest management of the species Croton guatemalensis. |

Antecedentes y Objetivos: Croton guatemalensis es una especie nativa que tiene diversos usos locales y juega un papel importante en la medicina tradicional de los habitantes de las comunidades campesinas de la Selva Zoque, Chiapas, México. Actualmente, la especie se encuentra protegida por la NOM-059-SEMARNAT-2010 bajo “Protección Especial”. El presente trabajo tuvo como objetivos evaluar la morfometría, viabilidad, sanidad y germinación de semillas recolectadas en poblaciones silvestres de cuatro Áreas Naturales Protegidas de la Selva Zoque, Chiapas, así como generar información básica que permita desarrollar en un futuro programas o proyectos locales de conservación, restauración y manejo forestal de la especie, para así contribuir a disminuir el impacto sobre las poblaciones silvestres.Métodos: De noviembre 2016 a octubre 2017 se recolectó material vegetal para corroborar la identificación taxonómica de Croton guatemalensis, y frutos y semillas para determinar, bajo un diseño al azar, el tamaño (longitud × grosor), peso, porcentaje de viabilidad, sanidad y germinación de las semillas. Debido a la anormalidad de los datos resultantes, la comparación y determinación de las diferencias estadísticas entre zonas se realizó mediante los análisis de Kruskal-Wallis y Mann-Whitney, por el software R 3.24.Resultados clave: Los resultados indican que existen diferencias estadísticamente significativas entre las cuatro zonas de recolecta. Los resultados más contrastantes se presentaron en la Zona Sujeta a Conservación Ecológica La Pera y Zona Protectora Forestal Vedada Villa de Allende. En la primera, las semillas presentaron mayor tamaño (5.13±0.06 × 3.26±0.06 mm), alto porcentaje de sanidad, viabilidad y germinación final (98±2.16, 98±2.30, 98±3.84%, respectivamente), mientras que en la segunda, las semillas fueron más pequeñas (4.63±0.09 × 2.69±0.08 mm), obtuvieron 68±6.65% de sanidad, 19±5.03% de viabilidad y 6±3.84% de germinación final.Conclusión: El presente estudio aporta información reproductiva fundamental para la generación de estrategias de conservación, restauración y manejo forestal de Croton guatemalensis.
