“…In this regard, our results indicate that tomato fruit decreased along without BAP application under heat stress, while application of 600 ppm BAP altered the impact of exceeded temperatures. The results are similar to those reported by other researchers who showed a variation in fruit quality and quantity depending on the cultivated variety and environmental conditions [62][63][64][65]. High temperature conditions could result in an increase in the TSS content in tomato fruits [66].…”

Heat stress is one of the most critical environmental abiotic stresses that can negatively affect plant growth. This article investigates the role of a plant growth promoter (Benzylaminopurine) in tomato fields in regard to its ability to withstand high-temperature conditions resulting from greenhouse gas emissions and climate changes. Three genetically different tomato cultivars (Castlerock, GS 12-F1, and Fayrouz F1) were sprayed with 2% 6-Benzylaminopurine (BAP) at 300 and 600 ppm; then, growth and yield components, physio-biochemical characteristics, and antioxidant enzyme activities were determined. The results showed that the highest BAP concentration (600 ppm) enhanced the ability of tomato plants to withstand high temperatures and the maximum dose of BAP improved chlorophyll (71.7 spad units) in GS 12 leaves, while the same dose enhanced proline contents (24.91 mg/100g FW), total antioxidants (83.35 µmol Trolox/g dw), total phenolics (20.99 mg/g dw), Superoxide dismutase (33.74 U/g), peroxidase (46.30 U/g), and polyphenol oxidase (64.10 U/g) in Fayrouz F1 leaves. Application BAP on tomatoes moderately improved fruit quality, such as ascorbic acid and maturity degree, while BAP applications reduced TSS and acidity. In this investigation, taste index was not affected by Benzylaminopurine application but by tomato genotype. The highest number of fruits/plant (45.7), fruit yield/plant (3.98 kg), and total yield (103 tons/ha) were obtained from the GS 12 genotype.

“…Chlorophyll b had high values at Sacher F1 hybrid, in the green fruit phase, and at Tiger F1 and Sacher F1 hybrids in the rose fruit phase (Table 2). Similar results were reported by Soare et al (2019) in a conventional tomato crop. Consequently, it can be stated that the organic culture system has directly influenced the accumulation of chlorophyll a and b in tomato fruits, a statement also supported by Khan et al (2017), who observed that chlorophyll a and b in tomato fruits can be significantly larger in organically fertilized plants.…”

“…Identifying tomato cultivars with high nutritional value is a useful approach that is taken into account when selecting those that have beneficial properties for better health. During the ripening process of tomato fruits, a series of quantitative and qualitative changes take place, which influence the aroma and volatile profiles of tomato taste (Soare et al, 2019). However, the increase or decrease in nutrients in tomatoes can be influenced by genotype, climate and soil conditions and the farming system.…”

Tomatoes (Solanum lycopersicum L.) are the most cultivated and consumed vegetable species in the world and deserve special attention due to their nutritional and functional value. The aim of this study was to assess the nutritional value of organically grown tomatoes in greenhouses, at different maturity phases. Five hybrids were studied: Antalya F1, Cemile F1, Lorely F1, Tiger F1 and Sacher F1. The observed parameters in each harvest phase were: Content of chlorophyll a and b, total carotenoids, total soluble solids (TSS), ascorbic acid (vitamin C) and titratable acidity (TA). Taking into account the content of TSS and TA, taste and maturity index was established. Tiger F1, Sacher F1 and Cemile F1 hybrids were significantly standing out for all analysed parameters. Sacher F1 had a carotene content of 10.3 mg 100 g -1 FW in green fruit and 17.0 mg 100 g -1 FW in red fruit. Vitamin C was 6.2 mg 100 g -1 FW in green fruits, increasing to 16.0 mg 100 g -1 FW in red fruits. The mineral content depended on the hybrid and harvest stage. In the rose phase the highest K content was in Cemile F1 (151.53 mg 100 -1 g), Ca in Lorely F1 (8.16 mg 100 g -1 ), Mg in Sacher F1 and Tiger F1 with values over 22.0 mg 100 g -1 , and Tiger F1 and Sacher F1 distinguish in Zn, Cu and Fe content. In the red fruit phase, Tiger F1 and Sacher F1 hybrids are representative for almost all minerals excepting Lorely F1 and Cemile F1.

“…Studies of Duma et al ( 32 ) showed that when comparing fruits mass and TI, it is observed that higher TI is for smaller or bigger tomatoes. Experiments of Rodica et al ( 23 ) showed that cherry and brownish red-colored tomatoes contain more soluble solids. In this study, it is underlined that quantity of the organic compounds determining the fruit taste depends on the yield of the cultivar.…”

Changes in Greenhouse Grown Tomatoes Metabolite Content Depending on Supplemental Light Quality

Tomatoes (Solanum lycopersicum L.) are good source of several biologically active compounds and antioxidants, especially lycopene, phenolic compounds, and vitamins. Tomatoes are found all over the world and are cultivated in a wide variety of environmental conditions. Light-emitting diode (LED) lamps are increasingly being used in the cultivation of tomatoes due to their cost-effectiveness and wide range of possibilities to adapt the spectrum of light emitted to the needs of plants. The aim of this study is to evaluate the effect of different additional lighting used in the greenhouse on the accumulation of biologically active compounds in different varieties of tomato fruit. Chemical composition—content of organic acids, lycopene, total carotenoids, total phenolics and flavonoids as well as dry matter, soluble solids content, and taste index were determined in five tomato cultivars (“Bolzano F1,” “Chocomate F1,” “Diamont F1,” “Encore F1,” and “Strabena F1”), which were cultivated in greenhouse in an autumn-spring season by using additional lighting with 16 h photoperiod. Three different lighting sources were used: LED, induction (IND) lamp, and high-pressure sodium lamp (HPSL). Experiments were performed during 3 years. Results showed that tomato varieties react differently to the supplemental lighting used. Cultivars, such as “Encore” and “Strabena,” are the most unresponsive to supplemental light. Experiments have shown that HPSL stimulates the accumulation of primary metabolites in tomato fruit. In all the cases, soluble solids content was 4.7–18.2% higher as compared to other lighting sources. As LED and IND lamps emit about 20% blue-violet light, the results suggest that blue-violet light of the spectrum stimulates the accumulation of phenolic compounds in the fruit by 1.6–47.4% under IND and 10.2–15.6% under LED compared to HPSL. Red fruit varieties tend to synthesize more β-carotene under supplemental LED and IND light. An increase of blue promotes the synthesis of secondary metabolites.
