Background and aims: Opuntia’s natural distribution encompasses from Canada to Argentina and it is part of the landscape in some regions of the world. There are between 191 and 215 Opuntia species. The ex situ conservation of this phytogenetic resource has gained relevance, but the species identification using the seeds is a limitation when there is a lack of reliable morphological traits. The purpose of this research work was to characterize the seed morphology of seven Opuntia species and identify their own morphological traits, in order to establish the species’ identification criteria when seeds are the only source of preserved plant material.
M&M: We used the attrition and image analysis technique to measure: seed coat thickness (GT), ventral funicular coat thickness (GCFV), embryo’s length, embryo’s surface area, major axis length and minor axis length. The most outstanding traits were detected through exploratory ANDEVA and main components methods. The species classification and forecasting were based on a supervised multivariate analysis. Results: Differences in all the variables among species were significant. Opuntia ficus-indica had the largest seeds. GCFV and GT were the most helpful variables in terms of discrimination. The main component analysis explained 92% of the total variation. K- Nearest Neighbor method was able to forecast correctly 83% of the species classification cases.
Conclusions: The assessed seed traits, mainly GCFV and GT, can help in the morphological description of prickly pear species and in the Opuntia species identification, when there are only seeds. |

Introducción y Objetivos: Opuntia se distribuye naturalmente desde Canadá hasta Argentina, actualmente forma parte del paisaje en algunas regiones del mundo, comprende entre 191 y 215 especies; la conservación ex situ de este recurso fitogenético ha adquirido relevancia, pero la identificación de especies por semilla es una limitante cuando no se tienen caracteres morfológicos confiables. El objetivo del estudio fue caracterizar la morfología de semillas de siete especies de Opuntia e identificar caracteres morfológicos propios, para tener un criterio en la identificación de especies cuando el material vegetal conservado es semilla. M&M: Mediante la técnica de desgaste y análisis de imágenes se evaluó: grosor de testa (GT), grosor de la cubierta funicular ventral (GCFV), longitud del embrión (LE), área del embrión (AE), longitud del eje mayor (LEMA) y del eje menor (LEME). Por medio de ANDEVA exploratorios y componentes principales (CP) se detectaron los caracteres más sobresalientes. Para la clasificación y predicción de especies se realizó un análisis supervisado con los métodos K-NN y LDA. Resultados: Las diferencias en todas las variables entre especies fueron significativas. Opuntia ficus-indica presentó semillas de mayor tamaño. Las variables que más ayudan a discriminar son GCFV y GT. El análisis de componentes principales explicó el 92% de la variación total. El método de predicción K-NN, fue capaz de predecir correctamente el 83% de los casos en la clasificación de las especies. Conclusiones: Los caracteres de semillas evaluados, principalmente el GCFV y GT, pueden coadyuvar en la descripción morfológica de las especies de nopal o o en identificación de especies de Opuntia cuando sólo se tiene semilla.
