Abstract

Abstract: Persimmon chilling injury can be due to lower activities of polygalacturonase , β2galactosidase , arabinanase and xylanase when the fruit were removed from cold storage (1 ±1) ℃and followed by the ripening at ambient
temperature (20 ℃) . As pre2heat treatment significantly enhanced the above cell wall hydrolase activities , the chilling injury index and firmness of persimmon were significantly lower than those of persimmon under cold storage , resulting in fruit ripening xormally.

Key words: Pre-heat treatment, Persimmon, Chilling injury, Cell wall hydrolases
