| description | Background and Aims: Peltogyne mexicana is the only species of the genus Peltogyne in Mexico, but its natural populations are subject to fragmentation processes and conservation strategies are needed. Nursery propagation can contribute to the conservation of the species, but appropriate germplasm management strategies must be developed. It is important to know the morphological characteristics of the seeds and their germination. The objectives of this work were: (1) to characterize the intrapopulation variation of some morphological traits (qualitative and morphometric) of P. mexicana seeds, and (2) to analyze the influence of size on germination.Methods: Traits such as color, shape, length, width, thickness, and weight of seeds of individuals of P. mexicana were described and characterized. The relationship between traits was examined with a Pearson correlation analysis and intrapopulation variation was tested with an analysis of variance. The influence of size on germination was also analyzed using logistic regression and the Weibull function, in all cases at a significance level of 5%.Key results: The seeds of P. mexicana are dark red with an ovoid shape. There is a high intrapopulation variation in traits. Width is the trait with the least variation, weight varies the most. All traits are significantly correlated with each other, but length and weight have the highest degree of association. Germination is significantly related to seed weight. The probability of germination increases as weight also increases. High germination rates occur for seeds weighing 0.65 g and germination occurs most frequently at 11.20 days.Conclusions: Seed morphological traits of P. mexicana vary intrapopulationally. Seed weight influences germination. |

Antecedentes y Objetivos: Peltogyne mexicana es la única especie del género Peltogyne en México, pero sus poblaciones naturales están sometidas a procesos de fragmentación, siendo necesarias estrategias de conservación. La propagación en vivero puede contribuir a conservar la especie, pero deben desarrollarse estrategias adecuadas de manejo del germoplasma. En esto es importante conocer las características morfológicas de las semillas y su germinación. Los objetivos de este trabajo fueron: (1) caracterizar la variación intrapoblacional de algunos rasgos morfológicos (cualitativos y morfométricos) de las semillas de P. mexicana, y (2) analizar la influencia del tamaño en la germinación.Métodos: Se describieron y caracterizaron rasgos como el color, forma, largo, ancho, grosor y peso de las semillas de P. mexicana. Se examinó la relación entre los rasgos con un análisis de correlación de Pearson y se probó la variación intrapoblacional con un análisis de varianza. También se analizó la influencia del tamaño en la germinación mediante regresión logística y la función de Weibull, en todos los casos a un nivel de significancia de 5%.Resultados clave: Las semillas de P. mexicana son de color rojo obscuro con forma ovoide. Existe una variación intrapoblacional alta en sus rasgos. El ancho es el rasgo con menor variación, el peso es el que más varía. Todos los rasgos se correlacionan significativamente entre sí, pero el largo y el peso tienen el mayor grado de asociación. La germinación se relaciona significativamente con el peso de las semillas. La probabilidad de germinación aumenta a medida que el peso también se incrementa. Tasas altas de germinación se presentan en semillas con un peso de 0.65 g y la germinación ocurre con mayor frecuencia entre los 11.20 días.Conclusiones: Los rasgos morfológicos de las semillas de P. mexicana varían intrapoblacionalmente. El peso de la semilla influye en la germinación.
