‘Xenia’ is a new and desired pear cultivar in Germany that is already spreading its cultivation to other European countries. The aim of this research was to determine the optimum storage conditions for ‘Xenia’ pear grown in the South of Germany. ‘Xenia’ was stored under regular air (RA), controlled atmosphere (CA) with 1.0 kPa O2 plus ≤ 0.7 kPa CO2, and 2.0 kPa O2 plus ≤ 0.7 kPa CO2 and DCA-storage based on CO2 monitoring (DCA-CD) for 9 months. The storage temperature in all conditions was 0 °C. In each storage system tested, pear fruit were divided into two batches: control (untreated fruit) and 1-MCP (pears treated with 1-MCP 300 nL L−1). At storage end, total soluble solids (TSS), glucose, fructose and sorbitol were higher in fruit treated with 1-MCP and stored under DCA. Pears kept in RA-storage showed the highest ethylene production and respiration rate, while those fruit under CA at 2.0 kPa O2, treated with 1-MCP, and DCA-storage had higher fruit firmness, TSS, titratable acidity, malic acid and greener peel color. The application of 1-MCP at 300 nL L−1 was effective in maintaining the quality of ‘Xenia’ pear, although its impact was dependent on the storage strategy, as well as this effect was mitigated under conditions with less than 1.0 kPa O2.
