| 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 ambienttemperature (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. |

| Keywords: | Pre heat treatment Persimmon Chilling injury Cell wall hydrolases |
