Abstract
Succinic acid -2,2-dimethylhydrazide (Alar) was applied at various postbloom spray intervals and concentrations to ‘Ranger’ peaches from 1965 to 1969 and to ‘Cardinal’ and ‘Blake’ peaces in 1969. Fruit of each cultivar was harvested at a uniform firmness to determine the influence of Alar on quality attributes not directly associated with changes in fruit maturity. Color attributes, particularly flesh color, were enhanced by Alar over a wide range of spray dates to a much greater degree than other quality attributes at a given maturity. The results indicated a stimulation of anthocyanin biosynthesis by Alar without a corresponding effect on other attributes normally considered to be indicators of physiological maturity.
