Ascorbic acid (mg/100 g), soluble sugar (%), titratable acid (%), and sugar acid ratio of the tomatoes for the control and leakage treatments (CO2 leakage during the tomato growth period). The blue and orange dots represent control and leakage treatments. The dashed line shows the tomatoes’ appropriate sugar acid ratio (6.9–10.8).
