Title: Growth and Yield Response of High Density Peaches and Nectarines from Annual Topping
Authors: M.J. Young and R.H. Sharpe
Cultural methods to control tree size and increase fruit production in high density orchards have received much attention in recent years (1, 8, 10, 12, 13, 14). Summer and traditional winter pruning have been used to check vegetative growth and facilitate other orchard operations (3, 6, 7, 11). Higher tree densities are being used to maximize early bearing potential (3, 5, 9, 11). The chronic problem of short tree life in the South, lack of dwarfing rootstocks compatible with commonly grown scion cultivars (4, 11) and pest damage have necessitated examination of alternative cultural systems. A long period of favor able weather after fruit harvest in May and June permitted examination of effects of postharvest topping on growth, yield and pest problems.
