Apples of the two varieties, Boskoop and Brettacher, were exposed to 35S labeled sulphur dioxide. After storage at several conditions the distribution of 35S-activity among the three fractions, sulphite, sulphate and sulphonate was examined. The major portion of the radioactivity was found in the sulphate fraction. The activity decreased remarkably from the peel towards the core. Appreciable differences in distribution patterns were found between the two apples varieties.
博斯科普和布雷塔赫尔这两个品种的苹果被暴露于35S标记的二氧化硫中。在几种条件下储存后，检测了35S活性在亚硫酸盐、硫酸盐和磺酸盐这三个组分中的分布情况。发现放射性的主要部分存在于硫酸盐组分中。从果皮到果核，活性显著降低。在这两个苹果品种之间发现了分布模式上的明显差异。
