摘　　要：弱光逆境是设施桃树栽培的主要限制因素之一,探明桃树对弱光逆境的生理反应,可以为优化设施桃树栽培技术体系和桃树耐弱光育种提供参考依据。从弱光逆境对桃树的生长发育、光合特性以及光合产物的转化与分配等方面的影响综述了国内外的相关研究进展,并分析了目前研究中存在的问题,展望了今后的进一步研究方向和途径。Low light stress is one of the main limiting factors to the protected cultivation of peach tree. Understanding its physiological responses to low light stress can provide some useful information for the optimization of protected cultivation technology and breeding of low light tolerant cultivars in peach tree. It was reviewed that the worldwide research advances on the effects of low light stress on the growth and development, photosynthetic characters, and photo-assimilation changing and partitioning in peach tree. Also, the problem in the present research was analyzed and the orientation and path in the further research was forecasted.
