Soluble solids, titratable acidity, fruit weight, ethylene emis sion and external color during the fruit development, from 15 days after pollination (DAP) to fruit harvesting (45 DAP) were determined. Changes in color correlated with the changing characteristics of melons. The research was focused on finding a chromatic index to appraise 'harvesting maturity' in a non-destructive way. Among the different relationships investigated (L/a; a/b; COL = 2000 a/ L.C; CCI = 1000 a/L.b; L/C) the L/C ratio, derived directly from the external reflectance of the fruit, showed the highest correlation with harvesting maturity (35 DAP)
