Information on the developmental stage of pear pre-harvest and in shelf-life is crucial to determine the optimum timing of harvest, post-harvest treatment, and time of consumption ensuring high eating quality. In the present study, CO emission and fruit quality of European pear ( L.) 'Conference' were analysed pre- and post-harvest with emphasis on shelf life for three years. Additionally, cytochrome and cyanide-resistant O consumption were analysed in the last year of experiments. The respiration rate of pear showed typical climacteric rise of CO emission in two years only, despite daily measurements. However, in each year the fruit quality in shelf life was closely linked to harvest date suggesting climacteric fruit response. Thus, the developmental stage of 'Conference' pear should be analysed by additional methods. Particularly, the cytochrome and cyanide-resistant O consumption showed an encouraging potential to obtain data on characteristic respiratory patterns.
了解梨采前和货架期的发育阶段对于确定最佳采收时间、采后处理和食用时间至关重要，以确保高食用品质。在本研究中，对欧洲梨（L.）‘康佛伦斯’采前和采后的CO排放和果实品质进行了分析，重点关注了三年的货架期。此外，在实验的最后一年分析了细胞色素和抗氰呼吸耗氧量。尽管进行了每日测量，但梨的呼吸速率仅在两年内呈现出典型的呼吸跃变期CO排放增加。然而，每年货架期的果实品质与采收日期密切相关，表明果实具有呼吸跃变反应。因此，应通过其他方法分析‘康佛伦斯’梨的发育阶段。特别是，细胞色素和抗氰呼吸耗氧量显示出获取特征呼吸模式数据的令人鼓舞的潜力。
