To determine whether ozone can regulate fruit ripening and delay aging, Kiwifruit (Actinidia deliciosa 'Guichang') was fumigated with different concentrations (100 μL/L, 200 300 μL/L) for 3 h, stored at 1 °C 85 ± 5% RH three months, then matured 20 85% 12 days. Compared controls, the optimal concentration of delayed kiwifruit during cold storage by delaying respiratory burst that precedes decay...
