Growth, yield, and fruit weight of spur-bound 'Delicious' apples treses following spur-pruning and BA plus, GA4+7 application
1991
Marini, R.P. | Sowers, D.
Twenty-eight-year-old 'Starkrimson Delicious' and 10-year-old 'Fullred Delicious' apple (Malus domestica Borkh.) trees were spur-pruned in 1986 and 1987 and/or treated with 500 mg BA + GA4+7/liter in 1986 in an attempt to improve spur growth and increase fruit weight. All treatment combinations generally failed to improve yield or fruit size. BA + GA4+7 reduced yield and fruit weight and increased the number of pygmy fruit in 1986, but had little effect on fruiting or vegetative growth for 3 years after treatment. Spur-pruning reduced spur density in 1986 and 1987 and increased yield, but not fruit weight, in 1987. Although spur-pruning improved spur length, spur bud diameter, leaf area per spur, and leaf dry weight per spur, fruit weight was not improved.
