DIVERSIDAD DE ESPECIES NATURALIZADAS DEL GÉNERO OPUNTIA (CACTACEAE) UTILIZADAS POR LOS POBLADORES DEL NORTE DE CÓRDOBA (ARGENTINA).

Diversity of naturalized species of the genus Opuntia (Cactaceae) used by the people of Northern Córdoba (Argentina). Agriculture understood as cultivation and domestication of plants constitute a practice orientated by botanical knowledge of different cultures. The study of plant diversity, cultivated and domesticated by a community is useful for understanding the underlying interests around them. In Argentina, particularly in Córdoba, there are few ethnobotanical research works about the relationship established between human groups and Cactaceae. That is why, in this study, an ethnobotanical research was conducted white creole inhabitants in the north of Córdoba. Methodology consisted of open and semistructured interviews, field exploration and herbarium material collection. We identified seven different kinds of “tunas", which have been collected from natural ecosystem and currently undergo domestication process. Six of them belong to the botanical species Opuntia ficus-indica (4 to form ficus-indica: “Amarilla", “Cordobesa", “Italiana" and “Salteña"; and 2 to form amyclaea: “Colorada" and “Blanca"), and the seventh belongs to the botanical species Opuntia robusta (“Cuaresma").
