摘要

[Objective] The physiological radiation spectrum and fruit quality in different canopies of sweet cherry tree were studied.[Method] Optical fiber spectrum was applied to determine the physiological radiation spectrum in different canopies of sweet cherry tree.The fruit quality in different canopies was determined.[Result] The results showed that from the top part to the lower part and from the outer part to inner part of sweet cherry canopy,the physiological radiation intensity and ratio of short wave light reduced significantly,while ratio of long wave light increased.Fruit mass,VC,TSS and total sugar content were significantly decreasing,while organic acid content increasing,but the fruit edible percent was similar.Furthermore,the physiological radiation intensity was strong,fruit mass,TSS,VC and total sugar content increased,but organic acid content reduced.[Conclusion] The higher and bigger canopy of sweet cherry,the poor and lower physiological radiation intensity,photosynthesis accumulation and fruit quality.The study provided theoretical foundation and reference for the trim of sweet cherry.
