“…Derivatives of caffeic acid (CA), p-coumaric acid (p-CA), and ferulic acid (FA) were the most abundant HCAs in the fruits. Similar HCA composition was reported for other tomato cultivars (Luthria et al, 2006;Anton et al, 2014). In tomato peel the decrease in CA and FA content was in correlation with PAR reduction for all 3 years, since no significant changes were observed between F1 and F2 (Figure 3; for significant CS effects see Table B2 in Appendix B).…”

Tomato (Solanum lycopersicum L.) is among the economically most important vegetables in Europe, valued for its bioactive properties due to significant contents of vitamins, carotenoids, and phenolic compounds. In this study, the tomato cultivar Big Beef F1 was grown in the open field (OF) and under polytunnels in central Serbia during 3 years. Polytunnels were covered with two foils (both with 57% reduced photosynthetic active radiation, PAR) differing in UV-A and UV-B transmittance. The aim of our work was to determine the influence of light conditions on accumulation of phytonutrients (carotenoids and phenolics) in the peel and flesh of ripe tomato fruits. The amount of effective antioxidants, caffeic acid, and quercetin (phenolics with ortho-dihydroxy substitution) in the peel was the highest in tomato fruits grown in the OF (maximal PAR and UV-A and UV-B radiation). Moreover, the content of leaf epidermal flavonoids was the highest in the OF. The content of lycopene and β-carotene in the flesh of tomato fruit was higher under the polytunnel with higher UV-transmittance. Our results showed that selection of the right light conditions (quality and intensity) for tomato production has a significant effect on the accumulation of beneficial phenolics and carotenoids.

“…The ultra-violet (UV) blocking characteristics of the standard plastic used for HTs was found to lower the total phenolic acid contents of tomato fruits by 20% as compared to UV-transparent plastic [41]. Similarly, high tunnels reduced the phenolic content of several leafy vegetables tested [42].…”

High tunnels have been used in the United States for more than 50 years, and growers are encouraged to use them more frequently through government cost-share programs. Research on fruits and vegetable production systems has focused on high value crops such as tomato, salad greens, and several fruit crops. Maintaining soil quality and controlling insects and diseases are all issues that growers face. This review looks at current research on these issues as well as economic considerations addressed in the scientific literature. Global statistics and reports are also reviewed that complement the North American studies. Gaps in our understanding are identified, and directions for future research are suggested.

“…Indeed, the literature showed that the micronutrient content of fresh fruits of different tomato varieties can vary significantly and it depending on the crop variety itself (Lenucci et al, 2006). Cropping practices, environmental factors, fruit maturity period and post-harvest storage can also cause changes in the composition of fruits of the same variety (Raffo et al, 2002;Slimestad & Verheul, 2005;Luthria et al, 2006). Part of the effective antioxidant activity of tomato could be also attributed to their phenolic compounds, mainly chlorogenic acid, rutin and gallic acid.…”

The availability of secondary metabolites in various plant parts can be influenced qualitatively and quantitatively by managing ecological factors or farming practices. Purpose of this study was to determine the impact of organic and mineral fertilization on the content of phenolic compounds and antioxidant activity in fruit of the tomato Mongal F1 variety. Experimentation was carried out in a randomized block factorial design. Results of study revealed that plant treated by organic fertilizers have 16.36± 0.07mg Trolox Equivalent (TE)/100g fresh tomato (ft) antioxidant activity and 6.96± 0.63mg Gallic Acid Equivalent (GAE)/100g ft total phenols content while the plant treated by mineral fertilizer have 15.57± 0.05 mg TE/100g ft for antioxidant activity and 6.09± 0.13mg GAE/100g ft for total phenols content. Furthermore, it was reported that, as compared to mineral fertilization, organic fertilization significantly increases the antioxidant activity and phenolic compounds production in Mongal F1 tomato variety. This increase is probably due to the availability of various major and minor elements in organic fertilizer contrary to mineral fertilizer which has only three major elements, nitrogen, phosphorus, and potassium. 79 days after transplanting, fruit ripping has no obvious effect on the accumulation of these compounds.
