GD, “Golden Delicious”; GR, “GoldRush”; WC, “WineCrisp”; PC, “Pixie Crunch”; CC, “CrimsonCrisp”; SSC, soluble solids content; TA, titratable acidity; Day 0, at harvest; Day 70, 70 days of storage at 0°C followed by 7 days at 20°C; Day 140, 140 days of storage at 0°C followed by 7 days at 20°C. Values for 1-MCP treatment before storage (Day 0) are the same as that for control. These values are kept due to statistical analysis and to assist with comparing the storage duration effects of each cultivar and each treatment. Data are presented as mean ± standard error (). Capital letters indicate mean separation among cultivars of each treatment and each storage day and lowercased letters show significant difference among storage duration treatments of each cultivar and each treatment by Tukey’s HSD at . Asterisks () indicate significant difference between control and 1-MCP treatment in each cultivar at each storage duration treatment by Student’s -test at . NS means nonsignificant. , ​, and ​​ mean significance at , 0.01, and 0.001, respectively.
