Abstract

Abstract:

The main research of this paper focused on the effects of hot air treatment (38°C 4d) on the wound healing of 'Gala' and 'Red Fuji' apple fruits. SEM (Scanning electron microscopy) analysis found that the epicuticular wax was melted by heat treatment, and then filled in the micro-wounds and encapsulated the hyphae, thereby, prevented the invasion by fungi. Artificial wounds cured for 4 days either at 20°C or 38°C before inoculation could decrease susceptibility to infection, and thereby, the decay development was reduced. But the effects of heating on the wound healing in apples were cultivar dependent. Compared to curing at 20°C, curing at 38°C accelerated the wound healing in 'Red Fuji' apple, but retarded the wound healing in 'Gala' apple.

Key words: apple, heat treatment, wax, wound, healing
