RESULTS
Postharvest BTH treatment of sweet potatoes promoted lignin accumulation in wounded tissues, and 100 mg L-1 BTH exhibited better effects than 50 mg L-1 or 150 mg L-1 BTH. The biosynthesis of lignin in wounded tissues significantly decreased the weight loss of sweet potatoes. An increase in respiration intensity after BTH treatment was observed. The total phenolic and flavonoid contents and the activity of phenylalanine ammonia-lyase, peroxidase, and polyphenol oxidase were increased in BTH-treated sweet potatoes. This suggests that BTH increases phenylpropanoid metabolism.CONCLUSION
Postharvest 100 mg L-1 BTH treatment could promote wound healing in mechanically damaged sweet potatoes. The activation of the phenylpropanoid metabolism might be the mechanism of action of BTH in wound healing. This article is protected by copyright. All rights reserved.
