Abstract
Sixteen hundred fruits were randomly collected from 16 kiwifruit (Actinidia deliciosa) orchards in Jeonnam, Gyeongnam and Jejn provinces in Korea in 2000 and incidences of postharvest fruit rots were examined. The overall disease incidence was 32% and varied much with locations of orchards ranging from 5 to 68%. The percentages of kiwifruits showing internal, external, and both internal and external symptoms were 21.9%, 4.9%, and 5.2%, respectively. Several fungi were isolated from rotten fruits; Botryosphaeria dothidea, Diaporthe actinidiae and Botrytis cinerea were the major pathogens with the average isolation rates of 83.3%, 11.9% and 1.4%, respectively. Based on the symptoms on kiwifruits and the characteristics, the postharvest fruit rots caused by B. dothidea and D. actinidiae are suggested to be named as ripe rots and stem-end rots, respectively.
