在美国麻萨诸塞州,于苹果采收前作矿质元素含量的分析。结合采收时测定糖/淀粉之比率可以成功地预测旭苹果的贮藏性能。利用原子吸收分光光度计对测定苹果组织中的钙、镁、钾、铜、锌、锰、铁等元素提供了迅速而精确的方法,还能调查苹果组织中阳离子的含量、比率和移动情况。许多研究报告指出了果实的低钙,特别是萼洼果肉中的低钙和苹果病害发生率有显著的相关性, Massachusetts in the United States before the apple harvest mineral elements for analysis. The storage performance of Asahi apple could be successfully predicted by measuring the sugar / starch ratio during harvest. The atomic absorption spectrophotometer provides a rapid and accurate method for the determination of calcium, magnesium, potassium, copper, zinc, manganese, iron and other elements in apple tissue. It can also investigate the cation content, ratio and movement in apple tissue. Many studies have reported a significant correlation between fruit low calcium, especially calyx pulp low calcium and apple disease incidence,
