Resumen:
The aim of this study was to evaluate the mineral content of ten garlic cultivars (all belonging  to the Argentinean germplasm and cultivated under identical agro-ecologic conditions). In  addition, four cultivars were planted in different geographic regions. The objective was to  observe how the environment influences the cultivars. Mineral profiles (Br, Rb, Na, La, Cr,  Cs, Sc, Fe, Zn, Co and Eu) were determined through Neutronic Activation Analysis (NAA).  The results obtained for mineral concentrations and trace elements of each sample constitute  the collection of data submitted to Multivariate Data Analysis (MDA) of principal components (PC). Hence, the general objective of this study was to determine whether the  mineral content of garlic cultivars was more influenced by genetics than by agro-ecologic conditions. We demonstrate that garlic cultivars cultivated under identical agro-ecologic  conditions can be categorized into groups by using just four metals as variables. It remains to be determined whether a methodology requiring the use of mineral profiles associated with a MDA constitutes an adequate tool for determining the geographic origin of garlic bulbs.
