Abstract

The fruits used in this study were harvested from eleven-year old 'Valencia' orange trees grown on calamandarin rootstocks. Under Los Baños conditions. 'Valencia' orange attained acceptable taste 24 weeks from full bloom, at which time the fruits had an average diameter of 71.8 mm. juice content of 32.2 ml per 100 gm of fruit and a solid to acid ratio of 12.3: 1 at 9.0 per cent total soluble solids. Rind color ranged from D to E in the standard color chart used for determining the color of the rind of oranges while flash texture was classified as coarse. The prime eating stage of 'Valencia' orange on calamandarin rootstock was attained about the 30th week from full bloom, when the average diameter of the fruit was 75.3mm, volume of juice 44.5 ml per 100 gm of fruits, and 18.8:1 of solid to acid ratio at 10.1 per cent total soluble solids. Rind color was D and flesh texture was normal
