The rootstocks were ‘Carrizo’, ‘C-35’, ‘Cleopatra’ mandarin, ‘Citrus volkameriana’, ‘Citrus macrophylla’, ‘Swingle’ citrumelo, ‘Forner-Alcaide 5’ and ‘Forner-Alcaide 13’. All studied parameters were highly rootstock/scion-dependent and showed changes throughout harvest. The content of the main anthocyanins revealed their relation with internal fruit color in both cultivars. The rootstocks that led to fruit with the lowest anthocyanins displayed the least sucrose content. The differences detected in the amount of hydroxycinnamic acids (chlorogenic, ferulic and sinapic) and flavanones (hesperidin, narirutin and didymin) related to anthocyanins content, explained phenylpropanoid pathway.
