Research Progress on the Response of Coffee Plants to Low-Temperature Stress
Coffee is a vital cash crop in the tropical and subtropical regions of the world.With the rapid increase in coffee consumption in China in recent years,the coffee industry has gradually occupied a crucial position in the prosperity of the economic development of ethnic minorities in the border areas and the promotion of rural revitalization in border areas.This paper searches the domestic and international literature with the keywords"coffee""low temperature"and"cold resistance"to understand the current status of research on coffee response to low-temperature stress and then summarizes the progress of domestic and international research on the cold resistance of coffee.Based on the previous studies,this paper summarized various aspects the effects of low-temperature stress on coffee growth,photosynthesis,physiological changes,and the mo-lecular basis of these effects.We summarized the strategies to improve the low-temperature tolerance of coffee from the as-pects of cultivar selection and exogenous regulation,as well as future research directions.
