Effect of 2 Kinds of Bud Grafting Methods on the Breeding of Fast-growing Peach Seedlings

The aim of the research was to discuss the factors that affected the survival rate of peach seedling,the percentage of seedling-selling and seedling growth.T-shaped budding and shield bud grafting with wood were used for peach grafting experiment at 3 stages.The effects of grafting methods and time on survival rate of grafting,the utilization rate of rootstock and scions,and the lifting rate of seedling in the current year were studied.After grafting for 20 d,the survival rate of seedling with T-shaped budding was higher than that of shield bud grafting with wood.The survival rate of seedling grafted in June 6th～16th was higher.The utilization rate of rootstock and scions with shield bud grafting with wood were higher than that with T-shaped budding and increased gradually with the delay of grafting time.The utilization rate of rootstock and scions with T-shaped budding were low in early stage and higher in late stage.The seedling rate and first-grade rate with T-shaped budding were higher.Shield bud grafting with wood had more seedling number and the number of first-grade seedling per unit area in nursery.The research provided scientific basis for mass and rapid breeding of seedlings in the production.
