“…Although many deleterious effects of salt on tomato plant growth and fruit production have been reported [9], in some cases, moderate salt stress can improve fruit quality [8,21,27,31,33]. Tomato plants irrigated with saline solutions transpire less water than tomatoes receiving fresh water [29,30,35], and the use of saline irrigation water as part of the integrated approach described by Ragab [28] has been pointed out by ReinaSánchez et al [29].…”

Cultivar photosynthetic performance related not only to capability for toxic ion exclusion, but also to the maintenance of appropriate essential macronutrient concentrations in leaves. In addition, the role of metabolic and diffusion limitations in regulating photosynthesis varied depending on the studied genotypes. These data, along with variation in biomass and ion distribution in leaves and roots, show that distinct tomato cultivars can address salt tolerance differently, which should be considered when designing strategies to overcome plant sensitivity to salt stress.

“…The genotypes which are least affected may be potential source of salinity tolerance for tomato breeding (Cuartero and Munoz 1999;Hazer et al 2006;Amir et al 2011;Hamed et al 2011). The effect of external salinity on seed germination may be partially osmotic or ion toxicity, which can alter physiological processes such as enzyme activities (Croser et al 2001;Essa and Al-Ani 2001).…”

“…Tomato seeds needed approximately 50 % additional time to germinate at 1 % NaCl than in control medium and almost 100 % more time at 3 % NaCl concentration (Table 1). Genotypes which germinate earlier at higher salinity are supposed to be more vigorous and may be used as parents or potential donor in salinity tolerance crop breeding programmes (Cuartero and Munoz 1999;Amir et al 2011;Hamed et al 2011). The stimulation of germination and days required for its completion, depend upon Gibbrelic Acid content in seed.…”

A study was conducted using ten genetically diverse genotypes along with their 45F 1 (generated by diallel mating) under normal and salt stress conditions. Although, tomato (Lycopersicon esculentum Mill.) is moderately sensitive to salinity but more attention to salinity is yet to be required in the production of tomato. In present study, germination rate, speed of germination, dry weight ratio and Na + /K + ratio in root and shoot, were the parameters assayed on three salinity levels; control, 1.0 % NaCl and 3.0 % NaCl with Hoagland's solution. Increasing salt stress negatively affected growth and development of tomato. When salt concentration increased, germination of tomato seed was reduced and the time needed to complete germination lengthened, root/shoot dry weight ratio was higher and Na + content increased but K + content decreased. Among the varieties, Sel-7 followed by Arka Vikas and crosses involving them as a parent were found to be the more tolerant genotypes in the present study on the basis of studied parameters.

“…Second, reduced water availability may have restricted nutrient (mainly N and K) uptake by the tomato plants, hence accumulating starch on the fruits and consequently affecting the brix values on the tomato fruits (Cuartero & Fernandez-Munoz, 1999;Saito et al, 2006). Third, the presence of the weeds may have altered the light quality and availability to the crop, which would further impact the fruit quality (Gautier et al, 2008).…”

-Five experiments were conducted to evaluate the hypothesis that Solanum americanum density and time of coexistence affect the quality of processing tomato fruit. The tomato crop was established using either the direct drilling or the transplanting technique. The factors evaluated consisted of weed density (from 0 up to 6 plants m -2 ) and time of weed interference (early bloom stage, full flowering stage, fruit filling, and harvest time). The effects of competition on tomato fruit quality were analysed using a multiple model. Tomato variables evaluated included industrial fruit types (which depended on ripeness and disease infection) and soluble solids level ( o brix). Tomato fruit quality is dependent on the factors tested. Under low densities (< 6 plants m -2 ) of S. americanum there was a small impact on the quality of the tomato fruits. The percentage of grade A (mature fruit with red color and without pathogen infection) tomato fruits is the variable most affect by the independent variables. The impact of these independent variables on the percentage of grade C (green and/or with more than 15% disease infection) tomato yield was of smaller magnitude and in an inverse trend as the observed for grade A. The level of soluble solids was influenced by the weed interference on only two experiments, but the impact was of small magnitude. The impact of the results on current and future crop management practices is discussed.Keywords: weed competition, critical period, density-dependent processes, threshold. Palavras-chave: interferência, período crítico, processos dependentes da densidade, nível de dano econômico. RESUMO -Cinco experimentos foram conduzidos para avaliar a hipótese de que a densidade de Solanum americanum e o tempo de convivência podem alterar a qualidade dos frutos do tomate para a indústria. O tomate foi cultivado usando-se o plantio direto ou a técnica de transplante. Os fatores avaliados consistiram da densidade de plantas daninhas (de 0 até 6 plantas m -2 ) e do tempo de interferência delas (fases de pré-florada, pleno florescimento, enchimento de frutos e colheita). Os efeitos da interferência sobre a qualidade dos frutos do tomateiro foram analisados utilizando um modelo múltiplo. As variáveis de tomate avaliadas foram tipos de fruta para indústria (em função da maturação e infecção da doença) e teor de sólidos solúveis ( o brix). A qualidade dos frutos de tomate é dependente dos fatores testados. Sob baixa densidade (<6 plantas m -
