Popis: Treatments with (2-chloroethyl)-phosphonic acid (ethephon) in the field initially caused green berries of cranberries (Vaccinium macrocarpon Ait.) to turn pink. Untreated berries increased in redness up to commercial harvest. Preharvest ethephon applications on mature, red berries caused no change in redness, but rather a decrease in yellowness, resulting in a change in hue, which may indicate a difference in relative amounts of the various pigments. Ethephon decreased the L reading of the berries, compared to the controls. Increasing the amount of water, in which the ethephon was dispersed, from 1.87 to 3.74 kliter/ha proved beneficial for coloring berries located deep in the vines not exposed to full sunlight. Ethephon treatments did not result in more rapid breakdown of the berries during storage. Only at extremely high rates of ethephon was berry size reduced. The commerci
