“…Due to the spatial and temporal variability in rainfall distribution, the semi-arid region of Northeastern Brazil favors water shortage and the increase in the concentration of dissolved salts in reservoirs, thus compromising the entire plant production cycle (Bezerra et al, 2018;Silva et al, 2019;Santana Júnior et al, 2020). High ion concentrations in the root region, especially Na + and Cl -, cause a series of morphophysiological disorders due to the osmotic and ionic effects of salt stress, thus decreasing water uptake and inhibiting nutrient uptake (Oliveira et al, 2018;Sousa et al, 2023).…”

Considering the relevance of bell pepper and the limitations imposed by the deleterious effects of salt stress, especially in semi-arid regions, it is extremely important to establish strategies that can facilitate the use of saline water in vegetable production. In this scenario, this study aimed to evaluate the effect of the frequency of foliar application of salicylic acid on the morphophysiology and production of the bell pepper cv. “All Big” irrigated with saline water. The study was conducted at a greenhouse in Campina Grande - PB. The treatments were distributed in a completely randomized design and set up in a 4 × 4 factorial arrangement with three replications, corresponding to four application frequencies of salicylic acid (F1- No application of salicylic acid, F2 - Weekly application, F3- fortnightly application, and F4- monthly application) and four levels of electrical conductivity of irrigation water - ECw (0.8, 1.6, 2.4 and 3.2 dS m-1). The fortnightly application of salicylic acid at a concentration of 1.0 mM mitigated the effects of salt stress on the morphophysiology and production components of bell pepper cv. All Big cultivated with ECw of up to 2.4 dS m-1, which reinforces the hypothesis that salicylic acid can act as a signaling molecule and reduce the effects of saline stress in bell pepper, enabling the use of brackish water in agricultural activity, mainly in semi-arid regions of northeastern Brazil, which have a shortage of fresh water.

“…High concentrations of ions in the root region of plants, mainly Na + and Cl -, trigger stress that causes ionic and osmotic effects, as it inhibits the absorption of K + and Ca +2 , because Na + competes with K + and Ca +2 for absorption sites on the cell membrane, causing nutritional disorders (Silva et al, 2022), inhibits water absorption, reduces leaf turgidity, plant growth and biomass production, and increases cell membrane degradation (Oliveira et al, 2018;Lima et al, 2020;Santana Júnior et al, 2020).…”

Considering the cashew tree’s relevance and the limitations imposed by salinity stress in semi-arid regions, the use of alternatives capable of mitigating the harmful effects due to salinity is of great importance to the production sector. The use of grafted plants, especially with rootstock made of tolerant materials, influences the accumulation of toxic ions in leaves of grafted seedlings. Thus, the objective of this work was to evaluate morphophysiological characteristics and leaf concentrations of Na+, K+ and Ca+2 of combinations of scion and rootstock of early dwarf cashew, contrasting in terms of salinity tolerance. The experiment was carried out in a completely randomized design with five replicates, in a 4 × 3 factorial arrangement, corresponding to four dwarf cashew scion/rootstock combinations (self-graft CCP 09, CCP 09/CCP 76, self-graft CCP 76, and CCP 76/CCP 09) and three NaCl concentrations (0, 50, and 100 mM L-1). Height, number of leaves, leaf area, dry matter, tolerance index and leaf concentrations of Na+, K+ and Ca+2 were evaluated after 30 days of application of NaCl concentrations. The scion/rootstock combination CCP 76/09 showed tolerance to 50 mM L-1, due to the increase of leaf area and number of leaves. The scion/rootstock combination CCP 76/09 was more suitable, as it kept the leaf K+ concentration and had the lowest Na+ concentration.

“…For example, at water salinity levels from 2 dS m -1 some cultivars, such as 'Princesa' , are sensitive. The Prata group cultivars better tolerate higher salinity levels (Santana Júnior et al, 2020). The use of plant growth-promoting bacteria (PGPB) has been cited as a potential way to mitigate the effects of salinity on banana plants irrigated with saline water (Chen et al, 2017;Baek et al, 2020;Silva et al, 2021).…”

Plant growth-promoting bacteria emerge as an alternative to attenuate abiotic stresses in plants such as salinity. The objective of this study was to evaluate the effects of Bacillus sp. strains 186 and 109 on the acclimatization of banana cv. ‘Prata Catarina’ irrigated with saline water. The experiment was conducted in a completely randomized design in a 4 × 2 factorial scheme, with 4 growth-promotion treatments, subjected to 2 levels of electrical conductivity of irrigation water. Irrigation with saline water decreased the number of leaves, leaf area, transpiration rate, stomatal conductance, and CO2 assimilation rate in banana leaves, regardless of inoculation with bacterial strains. The use of Bacillus sp. strain 109 promoted increments in phosphorus and iron contents in banana plants irrigated with low-salinity water.
