Abstract
The effects of bagging on the occurrence of black stain (BS) on fruit skin of 'Shinsyu' persimmon (Diospyros kaki L.) grown under a transparent film were investigated. All fruits of each tree were covered with paper bags on 17 September (the beginning stage of coloration), and all fruits of bagged and non-bagged trees were harvested on 22 and 27 October, respectively. The time required for bagging one fruit was about 21 seconds. Bagging significantly decreased the occurrence of BS and increased the ratios of BS-free fruit in two harvest dates by 4 to 7 times over the non-bagged ones. Bagging did not affect yield per tree, average fruit weight, fruit colour, flesh firmness, and total soluble solid content in two harvest dates. Suitable bagging dates for the prevention of BS are from 50 to 35 days before harvest.
