The efficacy of aqueous formulations of 1H-cyclopropabenzene (BC) containing different adjuvants to retard ethylene production and maintain fruit quality of Japanese plums (Prunus salicina Lindl. cvs. ‘Angeleno’, ‘Fortune’ and ‘Tegan Blue’) following 25 d and 40 d cold storage (1 °C) was evaluated. Plum fruit were sprayed with different solutions of 2 μM BC (i.e., aqueous solutions containing distilled water only or 5 % ethanol or 0.02 % Tween® 20 or 5 % β-cyclodextrin) or fumigated with 1 μM BC at ambient temperature. Plum fruit without any treatment were regarded as control. Regardless of the cultivars tested, all formulations of BC remarkably suppressed the ethylene production, while the fumigation was most effective treatment, when compared to control. Effects of BC on fruit firmness, weight loss and all other fruit quality parameters varied among formulations and cultivars. The fruit treated with BC had lower total anthocyanins levels than control whilst, total phenolic content and total antioxidant capacity did not differ significantly. BC solutions prepared containing 5 % ethanol or 0.02 % Tween® 20 outperformed other BC aqueous formulations in impeding production of ethylene and maintaining quality of cold stored Japanese plums.

含有不同佐剂的 1 H-环丙苯 (BC)水性配方对延缓乙烯产生和保持日本李子 ( Prunus salicina)果实品质的功效林德尔。简历。对冷藏 25 天和 40 天（1 °C）后的“Angeleno”、“Fortune”和“Tegan Blue”）进行了评估。用不同的 2 μM BC 溶液喷洒李子果实（即，仅含有蒸馏水或 5% 乙醇或 0.02% Tween® 20 或 5% β-环糊精的水溶液）或在环境温度下用 1 μM BC 熏蒸。未经任何处理的李子果实被视为对照。无论测试的品种如何，与对照相比，BC 的所有配方都显着抑制了乙烯的产生，而熏蒸是最有效的处理方法。BC 对果实硬度、重量减轻和所有其他果实质量参数的影响因配方和品种而异。用 BC 处理的果实的总花青素含量低于对照，而 总酚含量和总抗氧化能力没有显着差异。含有 5% 乙醇或 0.02% Tween® 20 的 BC 溶液在阻碍乙烯生产和保持冷藏日本李子质量方面优于其他 BC 水性配方。
