However,
no differences were observed between the control and the best treatment (2.5L/L) after 12 days (Fig. 5A) for disease incidence.
In the present study, fruit exposed to 1.5 and 2.5L/L ozone for
up to 96 h showed no phytotoxic effects (data not shown). Some
surface browning appeared on papaya treated with 3.5 and 5L/L
ozone continuously for 96 h (after 8 days of storage at 25±1 ◦C).
