摘　要：

库尔勒香梨(Pyrus sinkiangensis Yu)是新疆特色的优良梨品种, 栽培地域性极强, 在新疆特色林果业发展中有着重要的地位。低温冻害是库尔勒香梨产业发展的主要限制因子。国内许多学者对低温条件下香梨生理生化应答机制进行了大量的研究, 并取得了一些成果。基于前人的研究成果, 本文对库尔勒香梨的冻害成因、冻害症状、抗寒生理生化进行了较系统的综述, 并概述了库尔勒香梨的防寒措施, 提出了库尔勒香梨未来抗寒研究工作的展望。

Abstract:

Korla fragrant pear (Pyrus sinkiangensis Yu) is an excellent pear variety with local characteristics in Xinjiang, its cultivation demands a specific regional environment, and it plays an important role in the development of Xinjiang characteristic forestry and fruit industry. Low temperature freezing injury is the main factor which limits the development of Korla fragrant pear industry. Extensive researches have been carried out to study on the physiological and biochemical response mechanism of Korla fragrant pear under low temperature conditions and some achievements have been obtained. Based on the previous studies, the reasons of freezing injury, freezing symptoms and physiology and biochemistry characteristics were systematically reviewed in this paper, the cold-resistant measures of Korla fragrant pear was presented, and the related research work in the future was also involved.

Key words: Korla fragrant pear; freezing injury; cold resistance; research progress
