Abstract
Ethylene production rates of fresh market tomatoes (cv Caruso) were studied by applying aqueous calcium chloride solutions at 0.75% (w/v) and 1.5% (w/v) concentrations via vacuum infiltration. In all cases, calcium treatment at both concentrations inhibited ethylene production. Activities ACC synthase and EFE, and ACC and MACC concentrations of Caruso tomatoes were determined at mature green, pink and red stages of maturity, with and without 1.5% (w/v) CaCl2 infiltration. ACC synthase activity was not affected by calcium treatment at all the three stages of maturity, while EFE activity was lower in calcium treated tomatoes at the three stages.
