摘　　要：枇杷是一种秋冬季开花、果实成熟于初夏的亚热带果树,抗冻性较差。当遇到冬春季寒流时,极易出现花及幼果受冻,冻害严重时会极大的影响枇杷的产量和经济效益。现通过分析枇杷产生冻害的原因,结合枇杷花果冻害调查,对枇杷抗冻栽培研究现状进行了系统阐述,并分析综述了与枇杷抗寒性有关的生理指标。旨在通过综合分析与总结,为枇杷抗冻栽培技术体系的建立提供理论指导,从而采取适当的措施减轻枇杷冻害,提高经济效益。Loquat is a subtropical fruit tree,blooming in fall and winter,fruit ripening in early summer,frost resistance is poor,when encounteres the cold snap in winter and spring,flower and young fruit endures the cold easily,when freeze injure happenes seriously will greatly affect the loquat production and economic benefits.Now by analyzing the causes of loquat freezing injury,combined the cold injury survey of loquat flowers and fruits,expounded the research progress of loquat antifreeze cultivation and analyzed the physiological indexes related to the frost resistance in detail.Aimed at through comprehensive analysis and summary,providing theoretical guidance to establish the system of cultivation techniques for loquat antifreeze,so as to take appropriate measures to reduce the loquat freeze injury,to improve the economic benefits.
