Abstract

The ripening of discs cut from the pericarp of green tomato (Lycopersicon esculentum Mill.) fruits is inhibited by treatments with GA₃ and several divalent cations, including calcium. Normal ripening is marked by an increase in the solubility of wall pectins. Calcium and GA₃ alter the pattern of pectin solubility changes. In part this may be because polygalacturonase synthesis and/or secretion to the apoplast is reduced. The impact of divalent cations on ripening-related tissue softening appears to have a nonmetabolic component. Ripening-inhibiting ions rapidly reduce tissue softening, pectin solubilization and the normal ripening-related decrease in cellular turgor
