Summary:In Guerrero, Morelos and Chiapas states, Mexico, 102 collections of Mexican plum (Spondias purpurea L) were carried out, both at humid (49) and dry (53) seasons. Physical, physiological and chemical characteristics, and antioxidant activity, were determined. The weight of fruits fluctuated from 6 to 35g, polar and equatorial diameters were 22-44.6mm and 18.5-16.1mm; 19% of collections had a purple red epicarp (hue = 5.1-16.1), 30.4% red (17.2-49.8), 41.1% orange (50-70), 8% yellow (70-90), and 0.9% green (hue = 153.6). Total soluble solids varied 8.2 to 228[degrees]Brix, titratable acidity was 0.11-0.74% in epidermis and 0.10-0.81% in pulp. Respiration rate and ethylene production showed a large variatoin (CV = 81-107%). The largest concentrations of phenols, carotenoids and antioxidant activity were found in the epicarp, with high coefficients of variation (CV = 36-60%). Conglomerate analysis separated four groups: 1) the 53 humid season collectiosns, 2) 44 dry season collections, 3) three wild dry season collections and 4) two commercial dry season collections. The characteristics that separated the groups were chromaticity, hue, weight, dimensions, soluble solids content, total pulp carotenoids, titrable acidity in pulp and epicarp, and FRAP antioxidant activity in the pulp.
