Abstract
Apples cv. 'Jonagold' of the same quality were collected from four orchards in three European countries. The orchards differed in terms of longitude, latitude and microclimate. The apples were stored in controlled atmosphere storage for six months. Both after harvest and after storage the apples were compared in terms of physical and chemical properties. Differences in firmness, titratable acidity, total soluble solids, mass varied not more than 11%. Storability was little affected by harvest location. The sum of polyphenols was more strongly influenced by storage than by orchard location. The strongest degradation of flavonols after storage was in apples grown in the most southern region of harvest (Italy). The content of (+)- catechin and (-)-epicatechin depended on harvest location and its strong increase resulted in higher content of procyanidins and flavanols after storage. Changes in individual polyphenols were significant after storage and depended on harvest location.

蘋果從歐洲三個國家的四個果園采集到了品質(zhì)相同的Jonagold。果園的經(jīng)度、緯度和小氣候各不相同。蘋果在控制氣氛下貯藏六個月。對蘋果采后和貯藏后的理化性質(zhì)進(jìn)行了比較。硬度、可滴定酸度、總可溶性固形物、質(zhì)量變化不超過11%。采收地點對貯藏性影響不大。貯藏對多酚總量的影響大于果園位置。貯藏后黃酮醇的降解嚴(yán)重的是在收獲地南部地區(qū)(意大利)種植的蘋果。(+)-兒茶素和(-)-表兒茶素的含量取決于采摘地點，其含量的強(qiáng)烈增加導(dǎo)致貯藏后原花青素和黃烷醇的含量較高。貯藏后多酚含量的變化與采收地點有關(guān)。
