Abstract

Physicochemical properties of the tuber as a commercial product differ according to environmental conditions of the area and the growing season. The knowledge about how weather affects these characteristics, allows estimating the correct selection of the cultivars in order to obtain the highest yields or desired physicochemical qualities. In this sense, the effect of the main meteorological factors on the physicochemical characteristics (size, texture, dry matter, soluble solids, phenols, flavonoids, carotenoids and inhibitor concentration (IC50)) of 8 potato cultivars growing in A Limia (North-West Spain) was analysed. The study was conducted during three consecutive years (2014-2016) and the results presented significant differences in the analyzed parameters between years (P < 0.05). Spearman's correlations and principal component analysis showed that the tubers of 2014 (with colder weather conditions) had the highest phenol content and the lowest flavonoids and carotenoids content. Therefore, the temperature positively favoured the flavonoid content and carotenoid content (samples from 2016), although the size of potato tubers was considerably smaller.
