摘　　要：茶树原产于热带及亚热带地区,是一种喜温畏寒的植物,北方冬季寒冷干燥,会造成茶树的冻害。因此,茶树抗寒机理的研究对北方茶树的规模种植和增产具有重要意义。基于低温胁迫下茶树的主要生理变化,从糖代谢途径、Ca^(2+)信号途径,ABA、CBF/DREB诱导抗寒基因的表达几个方面综述了茶树的抗寒机理研究进展,并介绍了抗寒机理在茶树育种、栽培中的应用。Camellia sinensis was originated in the tropical and subtropical regions,which was suitable in warm rather than cold area. When planted in Northern China,tea plants were often usually destroyed by frozen damage in cold and dry winter.Therefore, researching the mechanism of cold resistance of Camellia sinensis was of great significance for the large-scale planting and yield increase of northern tea plant.In this research, we reviewed the main physiological changes and resistance mechanism of tea plant in low temperature with the aspects of carbohydrate metabolism pathway,Ca^2+ signaling pathway,ABA and CBF/DREB gene expression.In addition,application of the mechanism of cold resistance in tea plant breeding and cultivation was also introduced.
