Influence of Post-Flowering Climate Conditions on Anthocyanin Profile of Strawberry Cultivars Grown from North to South Europe

The effect of cultivar and environmental variations their interaction on anthocyanin components strawberry were assessed for six cultivars grown in five locations from North to South Europe two different years. To evaluate the impact latitude- altitude-related factors, daily mean (Tmean), maximum (Tmax) minimum (Tmin) temperature global radiation accumulated 3, 5, 10 15 days before fruit sampling, was analyzed. In general, fruits south more enriched total pelargonidin-3-glucoside (pel-3-glc), most abundant strawberry. Principal component analysis (PCA) provided a separation growing within due latitudinal climatic differences, temporary weather changes collection cultivation technique. PCA also depicted patterns distribution indicating specific reaction factors. linear regression showed that pel-3-glc relatively less affected by these while minor anthocyanins cyanidin-3-glucoside, cyanidin-3-(6-O-malonyl)-glucoside, pelargonidin-3-rutinoside pelargonidin-3-(6-O-malonoyl)-glucoside sensitive Tmax. strongly increased cya-3-mal-glc ‘Frida’ pel-3-rut ‘Florence’. ‘Candonga’ with radiation. profiles ‘Gariguette’ ‘Clery’ unaffected conditions.
