One of the main benefits from the chitosan application was decay control,
which was observed in both the pre- and postharvest applications. The postharvest
concentrations of 0.5, 1 and 2% reduced decay incidence by 75.5, 80.9 and 88.9%
respectively, at the 12
th
day, although the treatments extended the postharvest
life until the 15
th
day after harvest (Fig. 2a). In the pre-harvest application, the 1
and 2% concentrations reduced decay incidence by 13.98% and 27.96% respectively,
extending the postharvest life until the 12
th
day (Fig. 2b).
We found that the weight loss was slightly reduced by all pre- and postharvest treatments, but were not statistically different compared to the control (Fig. 2c
and d
