辣椒耐低温胁迫研究进展OA

Low temperature is a major limiting factor for protected cultivation of pepper in winter and spring as well as early-spring field production.Low temperature impairs multiple developmental processes including seed germination,seedling growth,flowering and fruit set,and fruit development;it also disrupts membrane system stability,chloroplast structure and photosynthetic performance.This paper reviews research advances regarding low-temperature injury symptoms in pepper,physiological and molecular regulatory mechanisms underlying pepper responses to low-temperature stress,the breeding of low-temperature-tolerant cultivars,and agronomic regulation strategies.Prospects for future investigations are also proposed,aiming to provide references for dissecting low-temperature tolerance mechanisms,screening low-temperature-tolerant germplasm resources,and facilitating stress-resistant breeding in pepper.
