“…Mineral composition of the cultivated tomato cultivars analyzed in this study is similar to that observed in other S. lycopersicum varieties reported in the literature [21,22]. However, there are some important differences in relation to the wild tomato cultivars considered, with mineral content higher than those habitually mentioned in the literature.…”

Tomato quality and its potential health benefits are directly related to its chemical composition. The characterization of nutritional properties of Solanum germplasm is essential to choose suitable donor parents for breeding programs. In this sense, wild species could be very useful for tomato fruit quality genetic improvement. With this objective, in this work, we characterize micronutrients content in Eulycopersicon germplasm (20 cultivars of S. lycopersicum L. and 10 accessions of wild relatives) analyzing mineral (Na, K, Ca, Mg) and trace elements (Cu, Fe, Zn, Mn) and applying multidimensional analysis (principal component and cluster analysis). The classification obtained and the comparison of cultivars performance showed that wild accessions belonging to S. cheesmaniae (L. Riley), S. pimpinellifolium L., and S. habrochaites S. Knapp & D.M. Spooner can be of great usefulness in breeding programs to improve mineral content characteristics of conventional S. lycopersicum varieties due to its higher mineral content.

“…There were no differences in glucose or fructose content whose values were similar to the maximum values reported by Figàs et al [13] and Lahoz et al [14]. While fruit and vegetable mineral element concentrations are strongly influenced by the content of those elements in the soil or nutritional solution [15], no significant differences were found in total Fe, Cu, or Zn. However, P, Na, K, Ca, and Mn differed significantly by cultivation system, and Mg by both cultivar and cultivation system.…”

Tomatoes have been described as a functional food because of their particular composition of different bioactive compounds. In this study, the proximate composition, minerals and trace elements, and antioxidant compounds were determined in two tomato cultivars (Mariana and Dunkan) that were grown in Gran Canaria (Spain) either conventionally or hydroponically. Although compositional data of this type require being subjected to the specific statistical techniques of compositional analysis, this approach has not usually been considered in this context. In the present case, a compositional Mann–Whitney U test of the data showed significant differences for each factor (cultivar and cultivation system) in several of the compositional variables studied. For the differences between cultivars, these parameters were the protein, Mg, lycopene, ascorbic acid, citric acid, and fumaric acid contents. For the differences between cultivation systems, they were mainly those of the mineral and trace elements group. Although one-year data are insufficient to make clear relationship among compounds because more repetitions in several localities and years are necessary, the compositional HJ-biplot (in which the links provide estimates of the linear relationship among variables) results agreed with other scientific results about linear relationship among some compounds analyzed.

“…Significantly greater maturity index in organic Amati fruit (11.7) and lower maturity index in conventional Elpida fruit (9.6) were found [21]. The maturity index in this study (in all cultivars in both production systems) were higher than those found by maturity index reported by [64] was 9.4 and therefore, it can be deduced that the maturity levels of the analyzed tomatoes were adequate for consumption. This ratio can also be affected by climate, cultivar and horticultural practices [28].…”

“…As with the sugars, the organic acids are crucial to the flavour of the fruits. The average contents Brix degree and acidity were 4.6 and 0.50 g 100 -1 of citric acid, respectively [64].…”
