“…Indeed, K + plays a role as cofactor of several enzymes involved in the biosynthesis of isopentenyl diphosphate, the first precursor of carotenoids in the mevalonate pathway (Trudel and Ozbun, 1971). Li and Yuan (2013) and Coyago-Cruz et al (2019) suggested that the fruit ripening-related accumulation of lycopene can also be influenced due to limited amount of sucrose. Overall, our results were in agreement with those found by Petersen et al (1998), which reported that salinity did not promote an increase of lycopene levels per dry weight in tomato fruits.…”

Salinity in Autumn-Winter Season and Fruit Quality of Tomato Landraces

Tomato landraces, originated by adaptive responses to local habitats, are considered a valuable resource for many traits of agronomic interest, including fruit nutritional quality. Primary and secondary metabolites are essential determinants of fruit organoleptic quality, and some of them, such as carotenoids and phenolics, have been associated with beneficial proprieties for human health. Landraces’ fruit taste and flavour are often preferred by consumers compared to the commercial varieties’ ones. In an autumn-winter greenhouse hydroponic experiment, the response of three Southern-Italy tomato landraces (Ciettaicale, Linosa and Corleone) and one commercial cultivar (UC-82B) to different concentrations of sodium chloride (0 mM, 60 mM or 120 mM NaCl) were evaluated. At harvest, no losses in marketable yield were noticed in any of the tested genotypes. However, under salt stress, fresh fruit yield as well as fruit calcium concentration were higher affected in the commercial cultivar than in the landraces. Furthermore, UC-82B showed a trend of decreasing lycopene and total antioxidant capacity with increasing salt concentration, whereas no changes in these parameters were observed in the landraces under 60 mM NaCl. Landraces under 120 mM NaCl accumulated more fructose and glucose in the fruits, while salt did not affect hexoses levels in UC-82B. Ultra-performance liquid chromatography–tandem mass spectrometry analysis revealed differential accumulation of glycoalkaloids, phenolic acids, flavonoids and their derivatives in the fruits of all genotypes under stress. Overall, the investigated Italian landraces showed a different behaviour compared to the commercial variety UC-82B under moderate salinity stress, showing a tolerable compromise between yield and quality attributes. Our results point to the feasible use of tomato landraces as a target to select interesting genetic traits to improve fruit quality under stress conditions.

“…Studies have suggested that sucrose is not detectable due to its acid invertase activity (Beauvoit et al, 2014;Figàs et al, 2015). Besides, sucrose is the main form of sugar translocation in tomato plants (Coyago-Cruz et al, 2019); it may explain why glucose and fructose were found at approximately equal amounts in tomatoes, while sucrose concentration was very low. Tomatoes in the full ripening stage exhibited 80 mg. g −1 fructose and 280 mg. g −1 glucose, while samples that were not considered ripe showed 100 mg. g −1 fructose and 400 mg. g −1 glucose.…”

“…Antioxidant mechanisms of fruit are constituted by enzymes and chemical groups that are able to prevent, inactivate and avoid propagation of free radicals, which also determine their positive effect on human diet (Borguini & Silva Torres, 2009;Ulewicz-Magulska & Wesolowski, 2019). Tomatoes (Solanum lycopersicum) are fruit that have been known as a good source of bioactive compounds, whose effects are related to antioxidant activity of carotenoids (lycopene and β carotene), phenolic compounds (phenolic acids and flavonoids) and ascorbic acid (Coyago-Cruz et al, 2019) with anticarcinogenic, antimicrobial, antimutagenic and anti-inflammatory properties (García-Hernández et al, 2018;Navarro-González et al, 2018). The supply chain has maintained tomato varieties that grow well at moderate temperatures ranging from 18 to 25 °C, low relative humidity and low rainfall from 5 to 6 consecutive months (Vallverdú-Queralt et al, 2012).…”

“…They are important factors to be taken into account in the evaluation of the role that these fruit play in human health (García-Hernández et al, 2018;Huang et al, 2005). Studies of genetic improvement effects on tomato nutritional and functional properties have been conducted by controlled experiments (Coyago-Cruz et al, 2019;Fattore et al, 2016;Li et al, 2017). However, genetic characteristics are affected by environmental and natural crop management.…”

“…Since in some production regions climate conditions are unpredictable, their effects on nutrients and functional compounds in tomatoes need to be evaluated to highlight their benefits and prevent damage to human health. The ability of a tomato variety grown in field conditions and available in markets to promote benefits to health can be determined by the profile of its bioactive chemical families (Borguini & Silva Torres, 2009;Choi et al, 2014;Coyago-Cruz et al, 2019). To evaluate its antioxidant potential by different procedures and to relate all factors by multivariate statistical techniques, such as the Principal Component Analysis (PCA), enable to identify the main chemical family which is responsible for the antioxidant potential.…”

Relations between nutrients and bioactive compounds of commercial tomato varieties by the Principal Component Analysis

This study evaluated relations among nutrients, bioactive compounds and antioxidant activity of commercial tomato varieties grown in field conditions in order to identify their biological potential by the Principal Component Analysis (PCA). Four commercial tomato varieties (Long Life, Italian, Khaki and Cherry), homogenized by their maturation stage (color, sugar/acidity ratio and pH) were evaluated regarding macro components (sugars, pectin and minerals) and functional ones (carotenoids, phenolic compounds and ascorbic acid). Cherry tomatoes stood out for their pectin and lycopene contents and their sugar/ acidity ratio. Tomato samples were good sources of Cu and Ca. The PCA showed that the antioxidant potential of phenolic compounds was related to protocatecoic acid and quercetin concentrations. Italian and Cherry varieties stood out for their carotenoid contents. In field conditions, Cherry and Italian tomatoes were the best sources of functional compounds among the most common varieties found in the human diet.

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.
