| description | Background and Aims: Prosopis laevigata, a widely distributed species in Mexico, is considered a resource with ecological and socioeconomic importance. Although its seeds and fruits have nutritional value, research on its morphological and anatomical variation is scarce. This study is the first to address the morpho-anatomy and histochemistry of the fruit and seed of P. laevigata and aims to contribute to the knowledge of its biology, as well as provide the basis for other research with an ecophysiological approach of this and other species of the genus.
Methods: Fruit and seed samples were collected from Prosopis laevigata trees in a locality of Lagos de Moreno, Jalisco, Mexico, to analyze their morphometric, anatomic, and histochemical characters. Additionally, its micro elemental composition was studied by scanning electron microscopy (SEM) coupled to energy-dispersive X-ray spectroscopy (EDS). ANOVA and correlation analyzes were applied to determine intrapopulation variability and association between morphometric variables.
Key results: The highest coefficient of variation (47.7%) was for the number of seeds per fruit. The ANOVA showed significant statistical differences for the variables seed length (F=7.51, p<0.0001) and seed width (F=8.75, p<0.0001); the highest correlation (0.937) was for fruit width-seed width. The fruits have an epicarp, mesocarp with calcium oxalate crystals and a leathery endocarp. The seeds present a pleurogram, subapical micropyle, and a thick seed coat with an epidermis of macrosclereids, and osteosclereids in the hypodermis. Cotyledons contain protein bodies and starchy endosperm. The testa and the embryo present macroelements (S, K, Mg) and microelements (Al, Si, Cu).
Conclusions: The morphological and anatomical characteristics and histochemical structure of fruits and seeds of the P. laevigata were similar to other Prosopis. The palisade epidermis, hypodermis with osteosclereids in the seed coat, stomata and prismatic crystals in the pods could represent important ecophysiological characters. |

Antecedentes y Objetivos: Prosopis laevigata, especie de amplia distribución en México, es considerada un recurso con importancia ecológica y socioeconómica. A pesar de que sus semillas y frutos tienen valor nutrimental, los estudios sobre su variación morfológica y anatómica son escasos. Este trabajo es el primero en abordar la morfo-anatomía e histoquímica del fruto y semilla de P. laevigata y tiene como objetivo contribuir al conocimiento de su biología y proporcionar las bases para otras investigaciones con un enfoque ecofisiológico en esta y otras especies del género. Métodos: Muestras de frutos y semillas fueron recolectadas de árboles de P. laevigata en una localidad de Lagos de Moreno, Jalisco, México, para analizar sus caracteres morfométricos, anatómicos e histoquímicos. Adicionalmente, se estudió su composición micro elemental mediante microscopía electrónica de barrido (MEB) acoplada a espectroscopia de rayos X de energía dispersiva (EDS). Se aplicaron análisis ANOVA y de correlación para conocer la variabilidad intrapoblacional y asociación entre variables morfométricas. Resultados clave: El coeficiente de variación más alto (47.7%) fue para el número de semillas por fruto. El ANOVA demostró diferencias estadísticas significativas para las variables longitud (F=7.51, p<0.0001) y ancho de la semilla (F=8.75, p<0.0001); la correlación más alta (0.937) fue para ancho fruto-ancho semilla. Los frutos presentan epicarpo, mesocarpo con cristales de oxalato de calcio y endocarpo coriáceo. Las semillas tienen pleurograma, micrópilo subapical, testa gruesa con epidermis de macroesclereidas y osteoesclereidas en la hipodermis. Cotiledones contienen cuerpos de proteína y endospermo con almidón. La testa y el embrión presentan macroelementos (S, K, Mg) y microelementos (Al, Si, Cu). Conclusiones: La estructura morfológica, anatómica e histoquímica de frutos y semillas de P. laevigata fueron similares a otros Prosopis. La epidermis en empalizada, hipodermis con osteoesclereidas en la testa de la semilla, los estomas y cristales prismáticos en las vainas podrían representar caracteres ecofisiológicos importantes.
