Abstract
Pink rot caused by wound-infected pathogenic fungus Trichothecium roseum is one of the most destructive diseases of harvested muskmelon.
Therefore, preventing the invasion of pathogenic fungus by promoting healing process provides a new possibility for controlling postharvest diseases of muskmelons.
Muskmelon fruits were sprayed with BTH during development in this study.
The roles of BTH sprays on wound healing were evaluated and related mechanisms were explored.
Results showed that BTH sprays elevated the level of endogenous SA, increased metabolic activity of phenylpropanoid, and promoted the synthesis of cinnamic acid, caffeic acid, ferulic acid and p-coumaric acid at wounds.
BTH sprays also increased the feruloyl transferase and peroxidase activities, thereby contributes to the accumulation of SPP and lignin at wounds.
In addition, BTH reduced water loss and inhibited lesion expansion of muskmelons inoculated with Trichothecium roseum. Collectively, we conclude that preharvest BTH multiple sprays accelerate the healing process of muskmelons by inducing endogenous SA synthesis and activating phenylpropanoid metabolism.
