Abstract
Chang Fu II apple tree with 18-year-old dwarfing interstock were used as experimental materials,which were subjected to root system pruning in different developmental stages,such late growth stage(autumn),sprouting stage and post-anthesis to investigate suitable periods of root system pruning.Photosynthetic characteristics of the leaves and fruit quality were measured.The results showed that root system pruning improved photosynthetic rate,stomatal conductance and intercellular CO2concentration.In the early growing season,root pruning reduced transpiration rate and improved water use efficiency,but there were little differences among treatments in late growing season.Root pruning in autumn had better photosynthetic capabilities to other treatments.Root pruning was conducive to improve fruit soluble solid,acid,vitamin C and anthocyanin contents,and the vividness of fruit surface and firmness of fruit were better.Autumn root pruning had better performance.Comprehensive analysis showed that autumn root pruning was more suitable on improving photosynthetic characteristics of leaves and fruit quality.
