摘要

“Xenia”是德国一种新的、受欢迎的梨品种，已经在欧洲其他国家推广。本研究的目的是确定生长在德国南部的“Xenia”梨的最佳储存条件。“Xenia”在常规空气（RA）、可控气氛（CA）（1.0 kPa O2 +≤ 0.7 kPa CO2、2.0 kPa O2 +≤ 0.7 kPa CO2）和基于CO2监测（DCA-CD）的dca储存下保存9个月。所有条件下的储存温度均为0℃。在每个测试的储存系统中，梨果实分为两批：对照（未经处理的果实）和1- mcp（用1- mcp 300 nL L−1处理的梨）。在贮藏端，1-MCP处理和DCA贮藏的果实总可溶性固形物（TSS）、葡萄糖、果糖和山梨醇含量较高。ra贮藏的梨乙烯产量和呼吸速率最高，而2.0 kPa O2 CA、1-MCP处理和dca贮藏的梨果实硬度、TSS、可滴定酸度、苹果酸较高，果皮颜色更绿。在300 nL L−1浓度下施用1- mcp可以有效地保持‘Xenia’梨的品质，尽管其影响取决于储存策略，并且在低于1.0 kPa O2的条件下，这种影响会减弱。

Quality of ‘Xenia’ pear under controlled atmosphere storage and 1-methylcyclopropene application

‘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.

期刊介绍： The journal is devoted exclusively to the publication of original papers, review articles and frontiers articles on biological and technological postharvest research. This includes the areas of postharvest storage, treatments and underpinning mechanisms, quality evaluation, packaging, handling and distribution of fresh horticultural crops including fruit, vegetables, flowers and nuts, but excluding grains, seeds and forages. Papers reporting novel insights from fundamental and interdisciplinary research will be particularly encouraged. These disciplines include systems biology, bioinformatics, entomology, plant physiology, plant pathology, (bio)chemistry, engineering, modelling, and technologies for nondestructive testing. Manuscripts on fresh food crops that will be further processed after postharvest storage, or on food processes beyond refrigeration, packaging and minimal processing will not be considered.
