abstract:
superficial scald is a physiological disorder that develops during cold storage aecting apples and causes substantial market losses. malus domestica cv. ladina, a new scab resistant and fire blight tolerant variety, commercialized in 2012, shows a physiological disorder similar to superficial scald after storage. here, we used dierent pre- and postharvest approaches to characterize the occurrence of these superficial scald symptoms in malus domestica cv. ladina. over a period of seven years, fruits from multiple orchards were stored for five to seven months and the occurrence of superficial scald was assessed in fruits after cold storage and controlled atmosphere (ca) storage. apples picked at dierent stages of ripeness within the same year diered in superficial scald development. additionally, superficial scald diered significantly between years and locations, strongly suggesting that maturity at harvest, weather during the growing season, and orchard management play important roles in scald occurrence. treatment with 1-methylcyclopropene (1-mcp) after harvest, and storage in a dynamically controlled atmosphere (dca) significantly reduced the occurrence of superficial scald, whereas storage under ultralow oxygen concentrations (ulo) showed mild but not significant eects. low calcium concentrations in the fruit flesh and peel were associated with stronger superficial scald occurrence.
浅表烫伤是苹果在冷藏过程中发生的一种生理性疾病，造成了巨大的市场损失。2012年商品化的抗赤霉病和抗火疫病新品种ladina，表现出与贮藏后浅表烫伤相似的生理障碍。在这里，我们使用不同的采前和采后方法来描述这些浅表烫伤症状的发生。在7年的时间里，对多个果园的果实进行了5-7个月的贮藏，并对冷藏和气调贮藏后果实表面烫伤的发生情况进行了评估。同一年内不同成熟期采摘的苹果在浅表烫伤发育过程中脱落。此外，浅表烫伤在不同年份和地点间的差异显著，强烈表明收获成熟度、生长季节的天气和果园管理对烫伤的发生起着重要作用。采后用1-甲基环丙烯（1-mcp）处理，在动态控制气氛（dca）下贮藏，可显著减少浅表烫伤的发生，而超低氧浓度（ulo）下贮藏则表现出轻微但不显著的效果。果肉和果皮中的低钙浓度与较严重的浅表烫伤有关。
