pear (pyrus communis l.) storage protocols are changing in the last years as new storage technologies have been emerged. since the discovery of 1-mcp and the development of the dynamic controlled atmosphere storage, research about the storability and ripening evolution of pears after storage have been intensified. depending on harvest maturity, growing region and orchard management, pears show different responses to 1-mcp treatment and storage conditions. the following text describes the main harvest indices for pears as well as the main storage procedures and conditions around the world. it was possible to separate the pear c*rs in three groups according with their tolerance to low oxygen or high carbon dioxide partial pressures, and to report about the main responses of pears to 1-mcp treatment regarding storage duration, occurrence of storage disorders and ripening evolution during shelf-life. one of the great new result presented herein is the possibility to store some pear c*rs at extremely low oxygen partial pressure as low as 0.5 kpa o2 for 8.5 months without occurrence of storage disorders and with adequate ripening evolution during shelf-life.
随着新的存储技术的出现，梨存储方法在过去几年中发生了变化。随着1-mcp的发现和动态气调贮藏技术的发展，对梨贮藏后的贮藏性能和成熟演化进行了研究。根据果实成熟度、生长区域和果园管理，梨对1-mcp处理和贮藏条件的反应不同。下文介绍了梨的主要收获指标，以及世界各地的主要贮藏程序和条件。根据梨品种对低氧分压和高二氧化碳分压的耐受性，可以将其分为三组，并对梨在贮藏期、贮藏障碍的发生和货架期成熟演化等方面对1-mcp处理的主要反应进行了研究。本文提出的一个重要的新结果是，在极低的氧分压(0.5 kpa o2)下将一些梨品种贮藏8.5个月，而不会出现贮藏障碍，并且在保质期内有充分的成熟演化
