Abstract

The present experiment addressed the effects of two harvest stages, namely breaker (S 1 ) and turning (S 2 ), on compositional and sensory profile of grafted, greenhouse elongated tomatoes cv. “Sir Elyan”. The rootstocks “He-Man”, “Interpro”, and “Armstrong” were used. The S 1 fruits showed a higher dry matter content, firmness and titratable acidity when compared to the S 2 ones (by 6%, 3%, and 15%, respectively). They showed, also, the highest L-ascorbic acid concentration and antioxidant activity. Differently, soluble solid content, lycopene and β-carotene increased in the S 2 fruits (by 4%, 92%, and 26%, respectively). Excepting methyl salicylate, all the volatiles detected peaked in the S 2 fruits, which were scored by panelists as sweeter and more flavorful than the S 1 ones. Among the rootstock genotypes, “He-Man” promoted fruits firmness, carotenoids concentration and antioxidant activity, irrespective of the harvest stage. “Interpro” enhanced the sensory attributes of the S 1 fruits in terms of bitterness, sourness, sweetness and flavor. Differently, sweetness, sourness, and tomato flavor of the S 2 fruits were promoted by “Armstrong”. The results highlight the influence of rootstock genotype on the nutraceutical and sensorial profile of “Sir Elyan” fruits harvested at early ripening stages.
