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。
Pyrus sink pear (Pyrus sinkiangensis Yu) is an excellent pear varieties in Xinjiang, the cultivation of extremely strong regional characteristics in Xinjiang fruit industry has an important position. Cold damage is Korla pear industry the main limiting factor. Many domestic scholars have carried out a lot of research on physiological and biochemical response mechanisms of pear under low temperature conditions, and achieved some results. Based on the research results of predecessors, this paper systematically reviewed the causes of frost damage, frost damage and physiological and biochemical reactions of Korla fragrant pear, and summarized the cold-proof measures of Korla fragrant pear and put forward the research work of future cold-resistant of Korla pear Outlook.
