ResumenThe purpose of this study was to assess the relationship between the effect of regulated deficit irrigation, cluster, developmental stages and two seasons (autumn 2015 and spring 2016) on the commercial and functional quality (carotenoids and plenolics levels) in ‘Lazarino’ and ‘Summerbrix’ tomatoes. Autumn had a positive effect on the commercial quality, with larger fruits (22% in ‘Summerbrix’; 26% in ‘Lazarino’) and higher soluble solids (16% in ‘Summerbrix’; 12% in ‘Lazarino’). Total carotenoids did not change significantly with irrigation and variety while total phenolics did with the cluster and season. In most cases, the main amounts of carotenoids and phenolic were found in the higher cluster and carotenoids in ripe fruit. Thus, irrigation of such varieties could be reduced drastically (ca. 80%) without affecting considerably the overall quality of their fruits (changes not greater than 30%).
