Figures S1 and S2 show the fluctuations of temperature and rainfall during the plant vegetation period (April-October) in 2011 as compared with long-term averages. Higher temperatures were recorded in 2011 when average monthly temperatures were higher than long term average. The summer of 2011 was distinguished by more rainfall in July and especially in August when double the normal monthly rainfall was recorded.

HPLC chromatograms of the extracts (λ=280, λ=320, and λ=360 nm) obtained from the apples of cultivars ‘Auksis’, ‘Ligol’, and ‘Šampion’ are depicted in Figures S3, S4, and S5. They allows the comparison of the chromatographic characteristics of extracts obtained from the apples of different cultivars as well as a variation in the quantitative content of catechins, procyanidins, phenolic acids, and flavonols in the apples of different cultivars.
