A non-destructive monitoring system that assesses low-oxygen stress of chlorophyll-containing fruit (HarvestWatch; Satlantic Inc., Halifax, N.S., Canada) was applied during storage. It allows for the changing of the atmospheric composition in the CA-room dynamically to the actual physiological state of the fruit (DCA), in contrast to the usually static conditions of CA storage. A decrease of the oxygen concentration to the lowest levels tolerated by the fruit should optimize the greatest benefits of ultra low oxygen (ULO) storage without risking losses caused by anaerobic conditions. The monitoring system is based on the measurement of chlorophyll fluorescence by means of FIRM (fluorescence interactive response monitor, Satlantic Inc.) sensors on samples of six apples.[...]
