Three-year-old‘Fujiminori’grapes grafted on‘SO4’were grown in sunlight greenhouse and three renewal pruning treatments(10,20 and 30 days after harvest)were set to compare the effects on the growth and fruit quality of‘Fujiminori’grape. The results indicated that the renewal pruning treatments could promote the germination of winter buds and the growth of new shoots at various extent,but the late renewal pruning treatment led to the short growth time of new shoots and the incomplete development of branches. Renewal pruning could effectively advance the phenological period of grape,of which the ripening of grape berries could be advanced with 20 and 13 days by renewal pruning at 10 and 20 days after harvest,respectively. Three renewal pruning treatments significantly increased the grape yield per plant,reaching 3 610.3,3 372.8 and 2 874.5 g,respectively,which were significantly higher than that of the control group(975.2 g). Renewal pruning treatments effectively increased the total soluble solids and anthocyanin content of grape berries,decreased their titratable acid content,whereby promoting berry ripening and quality improvement. Renewal pruning treatments at 10 and 20 days after harvest showed more significant effect mentioned above than late renewal pruning(30 days after harvest).
