“…Tomato fruits usually have a pH below 4.6, and, this way, they are considered acidic foods (Anthon & Barrett 2012). Although the citric acid concentration indicated fruits with a low acidity, in the present study, the fruits presented pH values below 4.6, agreeing with the results for tomato fruits found in the literature (Figàs et al 2015, Gatta et al 2015, Peixoto et al 2018.…”

Obtaining a high yield of good quality fruits is one of the main challenges of the tomato crop. The enhancement in plant density promotes a reduction in the fruit fresh mass and an increase the yield per area. On the other hand, commercialization parameters take into account number and fresh mass of fruits. This study aimed at evaluating the yield and fruit quality of indeterminate growth hybrid tomato (Rebeca), cultivated in a hydroponic system, with different planting densities and number of bunches per plant. The experiment was conducted under greenhouse conditions, in a sub-irrigation system containing expanded clay as substrate. A split-plot randomized block design, with three replications, was used. In the plots, four planting densities (11.1 plants m-2, 8.3 plants m-2, 6.6 plants m-2 and 5.5 plants m-2) were allocated and, in the subplots, the number of bunches per plant (one or two). The total yield was influenced by the interaction planting density x number of bunches per plant. The treatment that allowed the highest yield was 11.1 plants m-2 with two bunches, with 22.61 kg m-2 or 226.1 t ha-1, in a crop cycle of 134 days. The observed variations for the nutrient contents of leaves and fruits of tomato plants with one or two bunches, at densities of 5.5-11.1 plants m-2, do not compromise the fruit quality nor influence the production of tradable fruits, using the hydroponic system.

“…The average fruit mass may be influenced by environmental factors, genotypes, number of stems per plant, number of fruits per plant, planting density and number of seeds per fruit (Peil et al, 2014;Peixoto et al, 2018). In the present study, an inverse relationship between the number of fruits per plant and the average fruit mass was confirmed.…”

The objective of this study was to characterize genotypes of the salad-type tomato with a determinate growth habit and select genotypes resistant to the two-spotted spider mite for higher productivity and fruit quality. The experiment was conducted at the Horticultural Experimental Station (18°42’43.19” S and 47°29’55.8” W, 873 m altitude) of the Universidade Federal de Uberlândia (UFU), Monte Carmelo campus, from January to June 2018. The experimental design was in randomized blocks containing 16 treatments [12 populations of the F3RC2 generation and four controls: two commercial cultivars (Santa Clara and Rio Grande), the recurrent parent (UFU-057) and the wild species Solanum pennellii (LA-716)] with three repetitions. The accessions UFU-057F3RC210#3.6.1 and UFU-057F3RC213#2.1.2 have high potential for genetic improvement regarding resistance to the two-spotted spider mite. The genotypes UFU-13#4.4.1, UFU-7#4.7.1, UFU-7#4.3.2, UFU-13#2.5.2 and UFU-13#2.1.3 present higher acylsugar concentrations than S. pennellii, in addition to higher productivity and number of fruits per plant. It is suggested to explore combinations between those genotypes previously described with UFU-8#2.4.1 to obtain hybrids with high acylsugar concentrations, two-spotted spider mite resistance, high productivity and increased fruit mass.

“…It means that for consumers who like milder tomatoes, yellow fruit is recommended. The levels of vitamin C and total acidity are in agreement with research data reported in scientific literature (Peihoto et al, 2018, Pinela et al, 2016), but less than others (Asensio et al, 2019, Vinha et al, 2013. Taste index is parameter, which characterizes the quality and taste of tomatoes.…”

Tomatoes (Solanum lycopersicum L.) are known as very popular vegetable due to high nutritional value and are among the most commonly used vegetables in the world. Tomato varieties differ not only in fruit size, but also in colour. The aim of the present study was to evaluate how the colour of tomatoes influences the nutritional value. Chemical composition (vitamin C, lycopene, β-carotene, soluble solids, total acidity) and taste index were determined in 27 tomato cultivars grown in plastic film greenhouse without additional lighting. Red, pink, brown, orange and yellow tomato fruits were studied. The obtained results showed that there were significant differences in the mean values between analysed parameters according to the colour of fruit. The content of lycopene changed as follows: pink>red>brown>orange>yellow, but content of β-carotene: orange>pink>brown>red>yellow. The highest content of total acids (855.7±234.2 mg 100 g-1) as well as vitamin C (18.43±4.74 mg 100 g-1) was observed in orange tomatoes, but regarding taste index differently coloured tomatoes can be arranged as follows: brown>orange>pink>red>yellow. The smaller and bigger size tomatoes are recommended for consumers as tastier comparing with medium size tomatoes.
