Abstract
Effect of some preharvest spraying treatments such as potassium
sorbate (PS), chitosan (CH), propolis (PRO) and benzoic acid combined
with modified atmosphere (MA) to control postharvest decay and rots on
melon fruits caused by Fusarium semitectum, Aleternaria alternata, and
Rhizopus stolonifer were investigated. In vitro trials, potassium sorbate
showed the highest direct effect against the mycelial growth of all tested
fungi. Chitosan and propolis had the highest effect against A. alternata
and R. stolonifer, respectively. Benzoic acid showed the highest
inhibitory effect on the mycelial growth of all tested fungi. Modified
atmosphere in vitro had low effect at all tested concentrations among all
tested alternatives. In vivo trials, preharvest spraying treatments
combined with modified atmosphere showed a high level of protection
against development of postharvest rots of all tested fungi, in which
benzoic acid + Modified atmosphere was the most effective treatment.
Pretharvest spraying treatments combined with MA showed a low level
of activity for both peroxidase and polyphenol oxidase enzymes, as well
as significantly maintained the physical and chemical properties.
