Abstract

Overtree misting for bloom delay reduced fruit set of 'Golden Delicious' apple (Malus domestics Borkh.) flowers hand-pollinated with 'Jonathan' or 'Golden Delicious' pollen in 1978, or open-pollinated or hand cross-pollinated with 'Jonathan' pollen in 1979. Misting did not affect fruit set of flowers that were open-pollinated in 1978 or self-pollinated in 1979. The number of seeds per fruit was not reduced. Soil Ca, Mg, pH and base saturation of Ca and Mg were in-creased, and flower and spur leaves contained lower concentrations of N, P, K, B, Mn, Fe, Zn, and Cu at either full bloom or petal fall as a result of misting. Foliar sprays of B increased B concentrations but did not influence fruit set on either misted or nonmisted trees.
