GD, “Golden Delicious”; GR, “GoldRush”; WC, “WineCrisp”; PC, “Pixie Crunch”; CC, “CrimsonCrisp”. Data are presented as mean ± standard error (). Capital letters indicate mean separation among cultivars of each treatment and each storage day by Tukey’s HSD at . Lowercased letters show significant difference between storage durations of 70 and 140 days of each cultivar and each treatment, and 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.
