| 摘 要： | 以‘嘎拉’和‘红富士’苹果为对象，研究热空气处理（38°C 4d）对苹果伤口愈合的影响。扫描电镜观察发现，38°C 4d热空气处理能使苹果表面的果蜡融化，从而封堵微小伤口，并使真菌菌丝体胶囊化而失活，阻止病原菌的入侵。与人工刺伤后立即接种病原菌相比较，苹果伤口在38°C或者20°C下处理 4d后再接种病原菌能显著提高伤口的抵抗能力，降低伤口处病害的发生和发展。与20°C处理相比，38°C热处理有利于‘红富士’苹果人工刺伤伤口的愈合，但是不利于‘嘎拉’的伤口愈合。

| 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. |
