“…The WUE values in the production of tomato varied due to numerous factors (open air or greenhouse cultivation, variety, cropping cycle, growing system used, composition of the nutrient solution, management of irrigation, etc.). In numerous studies, values that oscillated between 26.0 and 17.0 kg m −3 in different conditions have been found . In this experiment, commercial unit production values lower than 0.55 kg kg −1 were found, probably due to the characteristics of the tomato plant used (cherry tomato).…”

BACKGROUND The current need to produce food for a growing population, from diminishing natural resources, such as water and energy, and with minimum environmental degradation, demands the optimization of production. We compare the economic feasibility of tomato production in an open system with a perlite substrate, a closed system with the nutrient film technique (NFT), and a hydroponic crop (deep flow technique, DFT) using three levels of salinity that are found within the normal range for irrigation water quality in southeastern Spain. RESULTS Production with DFT resulted in an increase in the cost of phytosanitary treatments and the cost of maintenance. Production with perlite resulted in an increase in the cost of irrigation water and fertilization, and the use of NFT resulted in an increase in energy costs. The point of price equilibrium was exceeded in the three soilless systems when using low salinity water, and in perlite, with intermediate salinity water. CONCLUSION Profitability was reduced in the following order: perlite > NFT > DFT. There were positive results when using irrigation water with low salinity, and in the case of perlite, with intermediate salinity. In every case, salinity reduced the profitability of the operation, and this was greater when NFT was employed. The analysis of these soilless systems should be continued to determine the possibility of reducing cultivation costs. © 2019 Society of Chemical Industry

“…Systematic sequencing of the Arabidopsis thaliana genome has identified 35 genes that can encode proteins being similar to antiport Na + /H + . Constitutive overexpression of AtNHX1 improves salinity tolerance also in tomato [124], Brassica napus [125], and soybean [126]. Fukuda et al have identified an AtNHX1 homologue in rice, OsNHX1.…”

Adaptation of Plants to Salt Stress: Characterization of Na+ and K+ Transporters and Role of CBL Gene Family in Regulating Salt Stress Response

et al. 2019

Salinity is one of the most serious factors limiting the productivity of agricultural crops, with adverse effects on germination, plant vigor, and crop yield. This salinity may be natural or induced by agricultural activities such as irrigation or the use of certain types of fertilizer. The most detrimental effect of salinity stress is the accumulation of Na+ and Cl− ions in tissues of plants exposed to soils with high NaCl concentrations. The entry of both Na+ and Cl− into the cells causes severe ion imbalance, and excess uptake might cause significant physiological disorder(s). High Na+ concentration inhibits the uptake of K+, which is an element for plant growth and development that results in lower productivity and may even lead to death. The genetic analyses revealed K+ and Na+ transport systems such as SOS1, which belong to the CBL gene family and play a key role in the transport of Na+ from the roots to the aerial parts in the Arabidopsis plant. In this review, we mainly discuss the roles of alkaline cations K+ and Na+, Ion homeostasis-transport determinants, and their regulation. Moreover, we tried to give a synthetic overview of soil salinity, its effects on plants, and tolerance mechanisms to withstand stress.

“…There are two principal strategies for controlling salinity: Establishing new irrigation and drainage systems or generating plants that are resistant to salinity. It has been shown that salinity stress during flowering negatively affects tomato plant yield by decreasing the number of fruits [1]. Plant response to salinity stress depends on the duration of exposure and salt levels.…”

Increasing Ascorbic Acid Content and Salinity Tolerance of Cherry Tomato Plants by Suppressed Expression of the Ascorbate Oxidase Gene

eg (M.I.A.M.) 2 INRA, UR1052, Génétique et amélioration des fruits et légumes, DomaineAbstract: Ascorbic acid is considered to be one of the most important antioxidants in plants and plays a vital role in the adaptation of plants to unfavorable conditions. In the present study, an ascorbate oxidase gene (Solyc04g054690) was over-expressed in cherry tomato cv. West Virginia 106 lines and compared with previously studied RNAi silenced ascorbate oxidase lines. Two lines with lower ascorbate oxidase activity (AO−15 and AO−42), two lines with elevated activity (AO+14 and AO+16), and the non-transgenic line (WVa106) were grown and irrigated with 75 mM and 150 mM NaCl in 2015 and 2016. Growth, yield, and chemical composition of the lines under salinity stress were evaluated. Lines with lower ascorbate oxidase activity resulted in higher plant growth parameters (plant height, leaf number, flower, and cluster number in 2015 and stem diameter and flower number in 2016), and improved fruit quality (firmness in 2016 and soluble solid content in 2015) and total yield per plant under salinity stress over both years. In addition, we show that ascorbic acid, lycopene, and carotene contents of fruits were higher in lines with lower ascorbate oxidase activity compared to lines with elevated activity and the non-transgenic line under conditions of moderate and high salinity in both years. cancer, including prostate, colon, and breast cancers [4]. Tomato fruits have a considerable amount of ascorbic acid (AA) (or vitamin C), which ranged from 84 to 590 mg/kg [5,6]. In addition, nearly one hundred grams of tomato can provide 40% of the recommended amount of AA for an adult's daily nutritional requirements. AA is considered to be one of the most abundant antioxidants found in the plant, including the apoplast [7]. There are several factors affecting AA levels in plants, such as the genetic background, environmental conditions, seasons, and abiotic stress, such as drought and salinity [8]. Previous work showed that application of exogenous AA leads to increased salt tolerance in tomato [2]. It was reported that breeders should be developing horticultural crops with high ascorbic acid content [9]. In plants, ascorbic acid is oxidized by ascorbate oxidase (AO) (an apoplastic enzyme) to mono-dehydroascorbate (MDHA) [10].The activity of AO plays a role in regulating the redox state (the ratio of reduced to total AA) of the apoplast [11]. A positive relationship has been found between the level of AO activity and abiotic stress tolerance. AO is also highly expressed in fruits and roots of tomato [12].Under-expression of the AO enzyme often leads to increased abiotic stress tolerance, such as to drought in tomato [11] and to salt in Arabidopsis and tobacco [13]. By contrast, the over-expression of AO leads to increased sensitivity to stress [7].In a previous study [11], West Virginia 106 cherry tomato cotyledons were transformed to create two RNAi silenced lines (AO−15 and AO−42) with lower AO activity. In this work, the authors found that t...
