A greenhouse experiment was conducted to study the effects of the application of a plant-derived biostimulant (Bioup TF) on fruit quality and composition of two clusters (cluster II and cluster VI) of the cherry tomato cultivars ‘Eletta’, ‘Kaucana’, and ‘Top Stellina’. The biostimulant application promoted fruit yield by 12% (up to 1.3 kg m-2 in ‘Kaucana’) and increased the concentrations of important functional constituents like phytoene, γ-tocopherol and β-tocopherol by up to 16, 25, and 23%, resp. Fruits from late-ripe cluster VI showed higher fruit weights, D-fructose, and total sugar contents than those from early-ripe cluster II (by 15, 7 and 5%, resp.), but reduced concentrations of acyclic carotenoids (phytoene and lycopene) and tocochromanols (mainly γ-tocopherol, -44%). ‘Top Stellina’ showed the highest responsiveness to the biostimulant, as particularly (all-E)-β-carotene, phytofluene, and γ-tocopherol concentrations increased, indicating a genotype-dependent effect of the treatment. However, fruits of all treated genotypes showed a contextual decrease in D-fructose and total sugars in response to the biostimulant (on average by 7 and 10%, resp.), indicating a metabolic load burdening the accumulation of lipophilic antioxidants in cherry tomatoes at the expense of their taste-related C pool.
