Sr isotope composition of Golden Delicious apples in Northern Italy reflects the soil ⁸⁷ Sr/⁸⁶ Sr ratio of the cultivation area.

ABSTRACT:

Background

Apples have a leading role in the Italian fruit sector, and high-quality apples, including the Golden Delicious variety, are cultivated mainly in the Northern mountain districts. In the present study, Golden Delicious apples from PDO (Protected Designation of Origin) and PGI (Protected Geographical Indication) cultivation districts were characterized according to their Sr isotope composition and compared with apples from other Northern Italian districts.

Results

Apples collected in two consecutive years (2017 and 2018) confirmed the low annual variability of the ⁸⁷ Sr/⁸⁶ Sr ratio. The isotope ratio of apples was highly correlated with that of the soil extracts of the respective orchards. Statistical differences were highlighted between cultiv
