Abstract: ‘Redhaven’ peach and ‘Stanley’ prune trees budded on dwarfing Prunus besseyi Bailey rootstocks were grown and fruited in greenhouse sand culture under 2, 90, 180 (control), 270, and 400 ppm Ca to study growth, fruiting, and fruit quality, 1970-72. Peach fruits were smaller, greener, and firmer and had less soluble solids and red blush at 2 and 90 ppm than at higher concentrations, and had poorer flavor at 2 ppm. Peach leaf Ca increased and fruit Ca decreased (except at 2 ppm) as Ca treatment levels increased. Optimum peach fruit quality was obtained when the Ca supply was 180 to 270 ppm and leaf Ca was above 2.00% dry weight. Prunes were little affected by Ca treatments, except that at 2 ppm most fruits dropped after fruit set and the few that remained were smaller and misshapen. Calcium accumulated to a higher level at a given treatment in prune leaves than in peach leaves.
