“…According to Baranska et al (2006), lycopene content in tomato ranges from 2.62 to 60.40 mg/100 g, and in tomato products from 18.8 to 629 mg/100 g. Lycopene content in showed genotypes is high; in Dunavski rubin it reached 106.7 mg/100 g, which is in accordance with study of Jongen (2002), but is higher than in study of Baranska et al (2006).…”

“…Dry matter content gives clear and specific instructions for directing technological process and provides significant data on raw materials utilization. Dry matter percentage depends on the cultivar, characteristics of the soil where it is grown, and especially on weather conditions -more sunny periods result in higher dry matter (Jongen, 2002). High dry matter percentage and high percentage of soluble solid substance are desirable characteristics in processing industry because they enhance the quality of the processed product (DePascale et al, 2001).…”

“…They are the carriers of flavour and they make 50-60% of dry matter, which is 2.19-3.55% of total tomato weight (Jongen, 2002). Sugar percentage in tomato fruit is primarily a cultivar trait and it ranges from 1.67 to 3.73% (Turhan and Seniz, 2009).…”

“…Soil rich in boron and zinc will increase vitamin C content. Average concentration is about 25 mg/100 g, which makes circa 40% of the average daily intake for an adult and 60% of the recommended daily intake for children (Jongen, 2002). According to Yahia et al (2001), minimum value of ascorbic acid (12.8 mg/100 g) was determined 18 days after the fruit formation.…”

“…When full ripening is reached, lycopene quantity can reach 88-106 mg/kg (Garcia and Barrett, 2006). According to Jongen (2002), lycopene content in ripen tomato fruits can reach 80-100 mg/kg, which is up to 85% of total carotenoids. Lycopene content is affected by water, fertilization, temperature and light, ripening level of the fruit, time of harvest (Dumas et al, 2003;Adeniyi and Ademoyegun, 2012;Ćota et al, 2013), fruit size, and storage conditions after the harvest.…”

BACKGROUNDHigh tunnels (HT) and plastic mulch can increase yield, extend growing seasons, protect plants from harsh weather conditions, and produce more marketable and attractive tomatoes. However, plastic covering reduces solar radiation, which may affect the quality of tomatoes. This study investigated the effects of single‐layer versus double‐layer HT and plastic mulch versus bare soil on the quality of fully ripe tomato fruits. The study was conducted over 2 years (2021 and 2022). The fruit color (L*, a*, and b*), vitamin C, pH, total titratable acid (TTA), total soluble solids (TSS), and lycopene content of the two tomato cultivars (Brandywine and Rebelski) were quantified.RESULTSThe results showed that quality parameters varied with the plastic layers of HT, plastic mulch, and planting year. The double‐layer HT only showed a slight but significant influence on the color of tomatoes of both cultivars in the same year (P < 0.05). Brandywine tomatoes grown in the double‐layer HT had significantly lower pH and lycopene content than those grown in single‐layer HT, regardless of mulching. The effect of plastic layers on TTA, TSS, and lycopene depended on whether the soil was mulched. Tomatoes grown on bare soil had higher TTA and TSS values than those grown on mulched soil in double‐layer HT. Tomatoes grown in single‐layer HTs had significantly higher vitamin C content than those in the double‐layer HT for both cultivars regardless of mulching.CONCLUSIONThis study demonstrates that double‐layer HT is unnecessary for the improvement of the overall quality of tomatoes. © 2023 Society of Chemical Industry.

The effect of covering material on the yield, quality and chemical composition of greenhouse‐grown tomato fruit

BACKGROUND During the last few decades, greenhouse technology for horticultural crops has focused on retaining optimum conditions within the greenhouse environment that could allow for a compromise between maximum yields and minimum production costs. The aim of this study was to evaluate the effect of three greenhouse covering materials and five harvesting dates on the yield and quality parameters of hydroponically produced tomato fruit, as well as on energy consumption. RESULTS Plants had a higher growth rate at early stages for S‐PE cover material, while differences were minimized at later stages. Tocopherol content was the highest for ID‐PE material and harvesting later than 170 days after transplanting (DAT), while sugar content (fructose and glucose) was the highest for S‐PE material and 157 DAT. Organic acid content was the highest at early harvestings, especially for 7‐PE and S‐PE cover materials, while it exhibited decreasing trends at later harvesting dates. Antioxidant properties showed a varied response to cover materials and harvesting dates, while β‐carotene, carotenoids and chlorophylls were the highest for 7‐PE material. CONCLUSIONS The results showed that both cover materials and harvesting date may affect significantly tomato fruit quality, especially sugar and organic acid contents which are associated with fruit taste, as well as tocopherols which contribute to antioxidant properties and pigments that are associated with fruit ripening and earliness of marketable maturity. © 2018 Society of Chemical Industry
