Improving blueberry cold storage quality: the effect of preharvest hexanal application on chilling injuries and antioxidant defense mechanisms

open access: yesJournal of the Science of Food and Agriculture, Volume 104, Issue 14, Page 8837-8851, November 2024.
Abstract Blueberries are vulnerable to chilling injury (CI). This can lead to limited longevity when they are subjected to cold storage conditions. This study investigated the effectiveness of a preharvest spray containing 0.02% hexanal in reducing CI and improving the postharvest storage quality of ‘Star’ and ‘Biloxi’ blueberries. The blueberries were
