The objective was to reveal the effects of ozone treatment on quality maintenance and resistance to Botrytis cinerea and Penicillium expansum in kiwifruit during postharvest storage. Kiwifruits were treated with 79.44 ppm gaseous ozone for 1 hr once a day for 7 day at 0°C to determine the effects of ozone treatment on the quality and disease incidence caused by B. cinerea and P. expansum in vivo and the growth of B. cinerea and P. expansum in vitro. Ozone treatment significantly reduced the disease incidence of kiwifruit and inhibited the mycelial development and spore germination of B. cinerea and P. expansum . High levels of fruit firmness and titratable acidity were maintained in the ozone‐treated kiwifruit, and the activities of the defence‐related enzymes were remarkably enhanced. Therefore, ozone treatment may be an effective method to maintain the quality of kiwifruit and control its decay during postharvest storage.
