The effects of two new ethylene antagonists namely 1H-cyclopropabenzene (BC) and 1H-cyclopropa[b]naphthalene (NC), as well as 1-methylcyclopropene (1-MCP) on ethylene production and fruit quality of Cripps Pink and Granny Smith apple in ozonized cold storage, were investigated. When compared to control, Cripps Pink fruit fumigated with BC and NC exhibited significantly lowest ethylene production and respiration, whilst the Granny Smith fruit treated with 1-MCP exhibited lowest ethylene production followed by NC and BC treatments. Application of ozone in cold storage maintained higher levels of sugars but elevated ethylene production in both the apple cultivars. No significant interaction was recorded between ethylene antagonists and ozone application in cold storage on the ethylene production, respiration and other fruit quality parameters. In conclusion, results suggest that BC and NC are potential ethylene antagonists in Cripps Pink and Granny Smith apples during the cold storage.
研究了两种新型乙烯拮抗剂 1H-环丙苯（BC）和 1H-环丙[a]萘（NC）以及 1-甲基环丙烯（1-MCP）对臭氧冷藏中 Cripps Pink 和 Granny Smith 苹果的乙烯生成和果实品质的影响。与对照相比，用 BC 和 NC 熏蒸的 Cripps Pink 果实乙烯生成和呼吸作用最低，而用 1-MCP 处理的 Granny Smith 果实乙烯生成最低，其次是 NC 和 BC 处理。在冷藏中应用臭氧保持了较高水平的糖，但两种苹果品种的乙烯生成均升高。在冷藏中，乙烯拮抗剂和臭氧应用之间没有记录到对乙烯生成、呼吸作用和其他果实品质参数的显著相互作用。总之，结果表明，BC 和 NC 是 Cripps Pink 和 Granny Smith 苹果在冷藏过程中的潜在乙烯拮抗剂。
