"Elucidating The Involvement Of Ethylene And Oxidative Stress During On- And Off-Tree Ripening Of Two Pear Cultivars With Different Ripening Patterns". Plant Physiology And Biochemistry 155: 842-850. doi:10.1016/
dc.description.abstractScarce information is available about the ripening process of European pears attached and detached from the tree. Accordingly, this study aimed to investigate the physiological and biochemical processes underlying both on- and off-tree fruit ripening in a summer (‘Conference’) vs. a winter (‘Flor d’Hivern’) pear cultivar. For each cultivar, a batch of fruit was harvested at the commercial harvest date and ripened at 20 °C and another batch was left to ripen on the tree. In both cultivars the inability of the fruit to soften on-tree, was related to a very limited ethylene metabolism but also associated to high content of H2O2 and low lipid peroxidation levels. In contrast, ripening in detached fruit was cultivar-dependent. In ‘Conference’ pears, the sharp firmness loss and colour changes observed during off-tree ripening were not strictly associated to an enhanced ethylene production but rather triggered by an oxidative related process preceding the climacteric rise. In contrast, ‘Flor d’Hivern’ pears experienced limited softening and degreening during off-tree ripening not being related to the action of ethylene or oxidative stress. Collectively our results showed that pear ripening was not exclusively dependent of ethylene production and that the fruit potential to limit oxidative damage may be involved with the inability of some European pear cultivars to ripen
