Effect of Ethylene Inhibitors on Quality Attributes of Apricot cv. Modesto and Patterson during Storage

Apricot (Prunus armeniaca L.) fruit are highly susceptible to flesh softening, loss of flavor and fruit decay, particularly during postharvest storage. Most of these quality changes observed during fruit ripening are under ethylene regulation. We performed a study with the objective of determining t...
