Abstract

Foliar calcium sprays applied every 14 days, starting two weeks after full bloom and continuing until one week before harvest, did not reduce surface discoloration or increase fruit quality of mid- or late season peach and nectarine cultivars. Multiple commercial calcium foliar sprays did not affect fruit soluble solids concentration (SSC), fruit firmness, fruit internal breakdown, and fruit flesh calcium concentration at harvest. Calcium concentration in the skin of the fruit was raised in three of the four varieties studied, leaf calcium was increased in two of the late cultivars.
