In experiment 1, fruit from cv. 'Oso Grande', that were treated
with chitosan at postharvest (Fig. 1A) or were not so treated
(Fig. 1B) showed similar behavior. Gray mold began to appear from
the seventh day of storage and reached an incidence of 50% at 22
days of storage. In experiment 2, fruit from cv. 'Camarosa' that were
not chitosan treated at postharvest exhibited gray mold at the
seventh day of storage, reaching an incidence of 74.0% at 22 days of
storage (Fig. 1C), whereas fruits of this cultivar that were chitosan
treated at postharvest achieved an incidence of 50.0% of gray mold
at 22 days of storage (Fig. 1D).
