摘要：

研究4 种不同贮藏条件（－1～0 ℃条件下5×10－6 m3/m3（以空气计）臭氧处理和5～6 ℃条件下2×10－6、4×10－6 m3/m3臭氧及2%～5% O2结合2%～4% CO2处理）对新疆厚皮甜瓜贮藏品质和生理特性的影响，贮藏过程中每15 d测定呼吸强度、乙烯释放速率、可溶性固形物含量、可滴定酸含量、pH值、果肉硬度、还原糖含量和过氧化物酶（POD）活性；贮藏68 d统计所有处理组甜瓜的腐烂和冷害情况。结果表明：低温冷藏（－1～0 ℃）条件下的甜瓜呼吸强度最低，但是出现了冷害现象，68 d时冷害指数为39%；贮藏于5～6 ℃条件下每日通入30 min2×10－6 m3/m3臭氧气体的甜瓜贮藏效果好于对照组，贮藏于5～6 ℃条件下每日通入30 min 4×10－6 m3/m3臭氧气体的甜瓜贮藏效果最好，其中呼吸高峰延迟出现，且呼吸强度降低，同时乙烯释放速率最小，还原糖含量、果肉硬度和POD活性较高，68 d时的腐烂指数仅为0.318；5～6 ℃环境下的气调（2%～5% O2）甜瓜可滴定酸含量最高，与其他处理组的差异性极显著（P＜0.01）；对照果实贮藏效果最差。

Abstract:

Xinjiang thick-skinned melon is a type of fruit which is extraordinarily favored by people, but it does not
withstand storage or transportation. This study was concerned with the effects of 4 different storage conditions i.e., a)
treatment with ozone at 5 × 10-6 m3/m3 (on an air basis) for 5 h every seven days during storage at −1–0 ℃; b) 2 × 10-6 m3/m3
ozone for 30 min every day during storage at 5–6 ℃; c) 4 × 10-6 m3/m3 ozone for 30 min every day during storage at 5–6 ℃;
and d) 2%–5% O2 + 2%–4% CO2 during storage 5–6 ℃, on the storage quality and physiological properties of Xinjiang
thick-skinned melon. Untreated fruits were used as control. With this aim, we determined respiration intensity, ethylene
production rate, soluble solids content, titratable acid content, pH, fruit hardness, reducing sugar content and peroxidase (POD)
activity of melon under these conditions were determined every 15 days of storage, and we also statistically analyzed decay
index and chilling injury index of melon fruits in all treatment groups after 68-day storage. The experiment results suggested
that low-temperature storage (−1–0 ℃) resulted in the minimum decay index, but caused chilling injury (the chilling injury
index after 68-day storage was 39%). The second treatment better maintained the quality of melon fruit than the control
group, and the third treatment provided the best maintenance of fruit quality as indicated by delaying the occurrence of
the respiratory peak, decreasing respiration intensity, minimizing ethylene production rate, and increasing reducing sugar
content, fruit flesh firmness and POD activity, consequently achieving a decay index of only 0.318 after storage for 68 days.
The highest titratable acid content was found in the fourth treatment, showing a highly significant difference as compared
with the other three treatment groups (P < 0.01). The control group was the least effective at preserving the quality of melon fruit.

Key words: Xinjiang thick-skinned melon, low temperature storage, ozone, controlled atmosphere, quality
