ABSTRACT: The evolution in a growing chamber of fruits from 10 Pineapple Guava (Acca sellowiana) cultivars belonging to a Pontevedra commercial plantation was studied. Cultivars were 'Apollo', 'Alpe', 'Coolidge', 'Castroviejo', 'David', 'Gemini', 'Mammoth', 'Triumph', 'Unique' and 'Vilagarcía'. Weight and length of collected fruits were recorded. At harvest and after maintaining the fruits at 2-4 ºC for 5, 10, 15 and 20 days dry matter, soluble solids, titratable acidity and starch content were determined along the period of evolution of the fruit subjected to these conditions. Weight and size of the fruit ranged among cultivars and even among fruits belonging to the same cultivar, which both affects commercialization and diffusion of the fruit. Larger fruits corresponded to 'Apollo' and 'Unique' cultivars and smaller fruits were 'Castroviejo' and 'Vilagarcía'. Fruits from most cultivars presented similar and stable values of dry matter, soluble solids, titratable acidity and starch content during conservation. The highest values of titratable acidity were obtained with 'Gemini' and 'Mammoth' fruits, but during conservation fruit acidity descended to levels similar to those of the other studied cultivars Keywords: Pineapple guava, cultivars, dry matter, soluble solids, titratable acidity, starch |
