Abstract:
In recent years，global climate warming and the frequent occurrence of extreme high-temperature events have posed serious threats to the normal growth and industrial development of kiwifruit.As a typical temperate fruit tree with a narrow optimal temperature range，kiwifruit is highly sensitive to heat stress，which can lead to leaf wilting，poor fruit coloration，and reduced yield and quality.This study systematically reviewed the phenotypic changes，physiological responsed，and molecular regulatory mechanisms of kiwifruit under heat stress.It focused on recent advances in understanding how heat stress impairs photosynthesis，activates the antioxidant enzyme system，promotes the accumulation of osmotic adjustment substances，affected cell membrane stability，and regulates gene expression.Additionally，differences in heat tolerance among various kiwifruit cultivars were summarized.Current research was primarily concentrated on the physiological level，while studied on molecular mechanisms remain insufficient，and there was a lack of standardized evaluation systems,in order to provide reference for future breeding of heat-tolerant kiwifruit varieties and the development of stress resistance strategies.
