“…On the other hand, in recent decades, H 2 O 2 has been widely investigated as a secondary messenger in signaling processes and in response to biotic and abiotic stresses (An et al, 2016;Choi et al, 2017;Nazir et al, 2019;Xie et al, 2019;Silva et al, 2022). For example, as mentioned earlier, H 2 O 2 is an essential component of the ABA signaling pathway that induces stomatal closure in drought stress conditions (Niu and Liao, 2016;Singh et al, 2017;Hsu et al, 2021).…”

It has long been hypothesized that hydrogen peroxide (H2O2) may play an essential role in root-to-shoot long-distance signaling during drought conditions. Thus, to better understand the involvement of H2O2 in drought signaling, two experiments were carried out using tomato plants. In the first experiment, a split-root scheme was used, while in the second experiment, the tomato plants were grown in a single pot and subjected to drought stress. In both experiments, H2O2 and catalase were applied together with irrigation. Control plants continued to be irrigated according to the water loss. In the split-root experiment, it was verified that the application of H2O2 to roots induced a clear reduction in plant transpiration compared to untreated or catalase-treated plants. In the second experiment, we observed that H2O2-treated plants exhibited similar transpiration when compared to untreated and catalase-treated plants under drought stress. Similarly, no difference in water use efficiency was observed. Thus, we conclude that the increase in H2O2 in the root system can act as a long-distance signal leading to reduced transpiration even when there is no water limitation in the shoot. But it has little effect when there is a reduction in the shoot water potential.

“…The semi-arid region of Northeast Brazil presents water restrictions in terms of quality and quantity, making the production of vegetable crops dependent on irrigation, which is often carried out with water that has a high salt content (Silva et al, 2024). Irrigation with saline water can cause the accumulation of sodium (Na + ) and chloride (Cl -) ions, and their excess restricts the absorption of water and nutrients by the roots of plants, compromising their growth and development (Hussain et al, 2021).…”

Salt stress caused by excess salts present in irrigation water, is one of the biggest barriers in agricultural production, especially in semi-arid regions. Thus, the use of substances, such as salicylic acid, that minimize the deleterious effects of salinity on plants can be an alternative to ensure satisfactory production. In this context, the objective of this study was to evaluate the effects of different methods of application of salicylic acid on the growth, production and water use efficiency of cherry tomato plants under salt stress. The study was conducted in a greenhouse, using an Entisol soil with a sandy loam texture. The treatments were distributed in a completely randomized design, in a 2×4 factorial arrangement, corresponding to two levels of electrical conductivity of irrigation water - ECw (0.6 and 2.6 dS m-1) and four methods of application of salicylic acid (Control - without application of SA; via spraying; via irrigation and via spraying and irrigation), with five replicates and one plant per plot. The salicylic acid concentration used in the different methods was 1.0 mM. Application of salicylic acid via foliar spraying increased the growth, production and water use efficiency of cherry tomato plants. The salt stress induced by the electrical conductivity of 2.6 dS m-1 was attenuated by the foliar application of salicylic acid. The use of water of 2.6 dS m-1 associated with the application of salicylic acid via irrigation water further intensified the adverse effects of salinity on cherry tomato plants.

“…In the semiarid region of Northeast Brazil, most groundwater sources contain high levels of salts which cause damage to agricultural production (Lima et al, 2018a;Lima et al, 2018b). Salt stress provokes deleterious effects on plants due to osmotic and ionic effects, limiting physiological and metabolic processes (Dias et al, 2019;Silva et al, 2022a). However, the damage to crop yield can be reduced by employing management strategies (Silva et al, 2021) adopted to decrease the harmful effect of salts (Medeiros et al, 2017), thereby avoiding soil degradation due to salinization.…”

The occurrence of water sources with high concentrations of salts in the semiarid region of Northeast Brazil stands out as a limiting factor in the cultivation of irrigated yellow passion fruit. Thus the search for irrigation strategies with brackish water is fundamental for the sustainability of irrigated crops. The objective of the present study was to determine the quantum yield, chlorophyll levels, and cell damage in yellow passion fruit cultivated under different irrigation strategies with brackish water and potassium fertilization. The experiment was conducted under field conditions in São Domingos -PB, Brazil, adopting a randomized block design in a 6×2 factorial scheme, consisting of six strategies of use of brackish water applied in the different phenological stages of crop and two doses of potassium (60 and 100% of the recommendation), with four replicates. Two levels of irrigation water salinity were used, with low (1.3 dS m -1 ) and high electrical conductivity (4.0 dS m -1 ). The potassium dose of 100% recommendation corresponds to the application of 345 g of K 2 O per plant per year. The use of brackish water (4.0 dS m -1 ) increased chlorophyll fluorescence and negatively affected the photosynthetic pigments of yellow passion fruit, regardless of the phenological stage. Salt stress intensified intercellular electrolyte leakage in passion fruit plants under higher dose of potassium. Our results show that fertilization equivalent to 100% of the potassium recommendation is excessive for yellow passion fruit 'BRS GA1' in the tropical semiarid region under salt stress conditions.
