Relationship among dry matter content and maturity indexes at harvest and quality of ‘Gala’ apples after storage

Abstract The objective of this study was to determine the relationship among dry matter content (DMC) and maturity indexes at harvest quality ‘Gala’ apples after storage. Apple fruit four strains produced on two rootstocks three growing regions were used for experiments 1 2. For all experiments, assessed one day stored removal from storage plus seven days 22 °C. experiment 1, harvested weekly along final stages growth maturation tree. 2, commercial under a controlled atmosphere 0.7 oC 195 days. 3, orchards in air 1oC 50, 110, or 194 DMC did not change during growth, however, there significant changes firmness, starch index, soluble solids (SSC) same period. At harvest, showed high correlation with SSC, titratable acidity (TA) firmness. also SSC TA but firmness flesh browning (FB). decreased slightly results show that is reliable index apple predict FB However, has potential storage, important traits.
