‘Golden Reinders’ apple quality parameters, fruit physiology, biochemical composition and susceptibility to Penicillium expansum and Rhizopus stolonifer were analysed in fruit harvested from four different locations (two valley and two mountain orchards) and from the same valley orchard at six different maturity stages. Growing location strongly influenced the taste- and health-related fruit composition whereas the fruit maturity at harvest mainly affected the ethylene biosynthetic pathway and ethylene-dependant quality traits such as the fruit firmness and starch index. The fruit maturity at harvest, but not the growing location, also affected the severity of the infection caused by P. expansum and R. stolonifer, with mature fruit showing higher susceptibility to pathogen infection. Besides, by employing a Partial Least Square (PLS) regression model, our data showed that the severity of the lesions caused by R. stolonifer were intimately related to the fruit ethylene production. Overall, the results from this study demonstrate that differences in environmental conditions between orchards (mountain vs valley) strongly influenced the composition of ‘Golden Reinders’ apples without affecting the susceptibility of the fruit to two major postharvest pathogens.

在四个不同地点（两个山谷和两个山区果园）和六个不同成熟阶段从同一山谷果园收获的水果中，分析了“金丝拒绝者”苹果的质量参数，果实生理，生化成分以及对青霉菌和根霉的易感性。种植位置强烈影响与口味和健康相关的水果组成，而收获时的成熟度主要影响乙烯的生物合成途径和乙烯依赖性的品质性状，例如水果的硬度和淀粉指数。收获时果实的成熟度，而不是生长地的果实，也影响了由P.expansum和R. stolonifer引起的感染的严重程度，成熟果实对病原体感染的敏感性更高。此外，通过使用偏最小二乘（PLS）回归模型，我们的数据表明，由斯托氏菌引起的病害的严重程度与果实乙烯的产量密切相关。总体而言，这项研究的结果表明，果园之间的环境条件差异（山脉与山谷）强烈影响了“金丝拒绝者”苹果的成分，而没有影响果实对两种主要采后病原体的敏感性。
