Supplementary file 1_Advancing sustainable greenhouse production through organic and integrated systems: effects on the bioactive profile and functional quality of diverse tomato hybrids.docx

Total sugar content was also 4.0% higher, and total antioxidant activity was 15.2% higher in organic production. A total of 74 polyphenolic compounds and 173 volatile aroma compounds were identified. Total polyphenolic content and antioxidant activity were significantly affected by production system and hybrid, with a highly significant interaction between the two factors (p < 0.01).

Significant differences were observed in the sugar composition, particularly for trehalose and melibiose, whose concentrations were higher in organically produced fruits (0.049 vs. 0.016 and 0.613 vs. 0.510 g 100 g⁻¹, respectively). Trehalose and melibiose showed potential as indicators of organically produced tomatoes. Overall, the results demonstrate that the production system influences the biochemical and nutritional quality of tomato fruits.

Organic production may be a suitable option for protected tomato cultivation, as it can contribute to higher levels of selected bioactive compounds and the production of safe, high-quality fruit.</p>
