Lemons are beneficial for human health due to their antioxidant activity, phenols and vitamin C. The objective of this Doctoral Thesis was to evaluate the effect of rootstocks on the quality of the fruit. The first experiment evaluated three rootstocks obtained in the Spanish stock breeding program [Instituto Valenciano de Investigaciones Agrarias (IVIA)]: citrus rootstock Forner - Alcaide 5 ('FA 5'), Forner - Alcaide 13 ('FA 13') and Forner‐ Alcaide 517 ('FA 517') grafted with four varieties of lemon (Citrus limon (L) Burm f.): 'Eureka', 'Verna', 'Fino 49' and 'Betera'. The second experiment investigated the two traditional rootstocks, (Citrus macrophylla Wester and Citrus aurantium L.) grafted with 'Fino 95', 'Fino 49' and 'Verna'. The third investigation consisted in determining the volatile profile of the bark oil of all the standard / graft combinations. The parameters evaluated in the fruit, in the first and second study were: morphological characteristics (color, weight, size, rind thickness, percentage of juice), chemical characteristics (total soluble solids, titratable acidity, maturity index, sugars and organic acids) and nutraceutical characteristics (antioxidant activity and total polyphenol content). As a result of the first and second trials, it was found that the rootstocks of the Forner Alcaide group influenced the decrease in the weight, size and thickness of the bark, but increased the percentage of juice and soluble solids. In the content of polyphenols and antioxidant activity, the rootstocks 'FA 13' and 'FA 517' showed the highest values in all cultivars studied. C. aurantium had better organoleptic properties than C. macrophylla. In the third experiment, the rootstocks that influenced the volatile compounds were from higher to lower concentration 'FA5'> 'FA517'> 'FA13'> C. aurantium> C. macrophylla and the more aromatic cultivars 'Eureka'> 'Bétera' > 'Fino 95'> 'Verna'> 'Fino 49'. These evaluations determined that rootstocks influence the physical, chemical, nutraceutical characteristics and the profile of volatile compounds. This research contributes to strengthening the need to continue evaluating rootstocks to obtain fruits in the appearance required by the consumer, but also in their internal properties such as the content of vitamin C and antioxidants important for health
