摘要: 以软儿梨为试材,研究了1?mL/L乙烯利处理对(20±3)℃、相对湿度85%~90%条件下贮藏的采后软儿梨果实后熟期生理和品质指标的影响。结果表明:采后乙烯利处理软儿梨果实能够提高果实乙烯释放量并使其呼吸高峰提前2?d出现,加速了果实的后熟;在后熟第16天时,乙烯利处理组果实的质量损失率(5.4%)显著低于对照组果实(6.1%)(P<0.05),提升了果实的色泽,但就整个后熟过程而言,对果实的硬度、还原糖、可滴定酸和石细胞含量无显著性影响(P>0.05)。

Abstract: The effect of postharvest treatment with 1 mL/L ethephon on the physiological and quality attributes of Ruan’er pear fruits during ripening at relative humidity of 85%–90% and (20 ± 3) ℃ was investigated. It was shown that postharvest ethephon treatment could elevate ethylene release and result in earlier occurrence of the respiration peak in fruits by 2 days, thus accelerating fruit ripening. After 16 days of ripening, the percentage weight loss of ethephon-treated fruits (5.4%) was significantly lower than that (6.1%) of the control group (P < 0.05). Ethephon treatment improved the color of pear fruits, but for the whole ripening process, the treatment had no significant effect on the firmness, reducing sugar, titratable acidity and stone cell contents of the fruits (P > 0.05).

Key words: fruit, ripening, ethephon, postharvest physiology, quality
