Abstract: To understand the regulating mechanism of photosynthesis by leaf end-products accumulation in fruit trees after sink-source manipulation, this review summarized several hypotheses that likely involved in the regulating mechanism of photosynthesis regulated by leaf end-products accumulation after sink-source manipulation in fruit trees, and pointed out some shortages of the back forward inhibition hypothesis. Moreover, a new hypothesis that stomatal conductance was promoter and leaf temperature was actor was presented. Finally, the review proposed some research key points in order to understand this mechanism more comprehensively in the future.
