摘要: 柿果实冷藏后移到常温下后熟时, 果肉组织的内切-多聚半乳糖醛酸酶、β-半乳糖苷酶、阿拉伯聚糖酶、木聚糖酶活性受到抑制, 引起果实冷害发生。贮前热处理能显著提高这几种酶的活性, 从而降低冷害指数, 使果实正常软化。

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
