Other claims from this paper (11)
- Intervention effect Harpin Ea significantly reduced top rot incidence with over 75% control across consecutive seasons.
- Intervention effect Harpin Ea increased fruit yield by over 9%.
- Intervention effect Harpin Ea exhibited negligible direct antifungal activity in vitro, with 3.39-8.25% inhibition.
- Intervention effect Harpin Ea enhanced antioxidant enzyme activities.
- Intervention effect Harpin Ea elevated defense-related compound levels.
- Intervention effect Harpin Ea improved photosynthetic performance.
- Intervention effect Harpin Ea reinforced fruit epidermis and cell walls and increased cellulose, lignin and carbohydrates by 102-200%.
- Intervention effect Harpin Ea upregulated the phenylpropanoid-flavonoid pathway and enhanced expression of PAL, 4CL and CHS genes.
- Intervention effect Harpin Ea promoted accumulation of p-cinnamic acid, caffeic acid and phenylalanine.
- Intervention effect Harpin Ea promoted accumulation of naringenin, quercetin and hesperidin.
- Mechanism Harpin-induced resistance is mediated by synergistic physical barrier enhancement and activation of phenylpropanoid-flavonoid metabolism.
