Abstract
‘Huaizhi’ and ‘Nuomici’ are two of the most widely planted litchi cultivars in South China.
Activities of chitinase,
-1, 3-glucanase and peroxidase increased in the peel of‘Huaizhi’ and ‘Nuomici’ after inoculation with Peronophythora litchii, which was one of the most troublesome pathogens in China.
These enzymes were pathogenesis-related proteins in infected fruit.
The inoculation also induced an increase in glutathione (GSH) and ascorbate (Vc) contents.
There were much higher activities of these enzymes, GSH and Vc, and less disease in‘Huaizhi’than in‘Nuomici’, which did not store as well.
It was suggested that the resistance to postharvest diseases was related to antioxidants, pathogenesis-related proteins and peel texture.
