title: [Behavior of Ethephon residues on stone fruits and berries. 1. Ethephon residues on sweet and sour cherries].
abstract: The authors describe a gas chromatographic method for determing Ethephone residues. Studies on the residual behaviour of Ethephon on sweet cherries showed that the fruits contained 0.88, 1.45 and 1.83 p.p.m. of Ethephon after applications of 0.05, 0.075 and 0.1% Flordimex mixture, respectively. When the same doses were applied to sour cherries, the fruits contained 0.54, 1.12 and 1.44 p.p.m. of Ethephon; and the juices, 0.81, 1.36 and 1.77 p.p.m.
