“…Among the strategies that allow mitigating the effects of salt stress on plants, a prominent one is the use of elicitor substances, such as salicylic acid, an important signaling molecule that mitigates the adverse effects of salt stress on plants through the improvement in physiological and metabolic processes, resulting in their acclimatization to abiotic stresses, including salt stress (SILVA et al, 2020;LACERDA et al, 2022b;XAVIER et al, 2022).…”

The objective of this study was to evaluate gas exchange, biomass, and quality of guava seedlings as a function of the cationic nature of the water used in irrigation and foliar application of salicylic acid. The experiment was carried out in a greenhouse in Pombal, PB, Brazil, using a randomized block design, in a 6 × 4 factorial scheme with six cationic compositions of irrigation water [S1 - Control (supply water); S2 - Na+; S3 - Ca2+; S4 - Na++Ca2+; S5 - Mg2+, and S6 - Na++Ca2++Mg2+], associated with four concentrations of salicylic acid (0, 1.3, 2.6, and 3.9 mM), with 3 replicates. Plants in control (S1) were irrigated with water of electrical conductivity (ECw) of 0.3 dS m-1, while in the other treatments were irrigated with different types of water and had an ECw of 4.3 dS m-1, consisting of different cations, in the form of chloride. In the seedling formation phase, guava plants were sensitive to calcic water, which resulted in a marked decrease in their growth. Stomatal conductance, transpiration, and biomass accumulation of guava seedlings were more affected by variation in electrical conductivity than by cationic nature of the water. Salicylic acid at concentrations of 2.9 and 1.9 mM increased stomatal conductance and stem dry biomass, respectively, of guava seedlings. Water with ECw of 4.3 dS m-1 allowed the formation of guava seedlings with acceptable quality for transplanting to the field, regardless of the cationic nature of the water.

Guava is a fruit widely produced in Northeast Brazil, a region that has sources of water with high levels of salts, making it difficult for irrigated fruit production to expand. Thus, it is extremely important to search for techniques that allow the management of these waters in irrigated agriculture. Thus, the objective of present study was to evaluate the photosynthetic pigments, the quantum yield of photosystem II, and the intercellular leakage of electrolytes in the leaf blade of ‘Paluma’ guava seedlings as a function of irrigation with water of different salinities and foliar application of salicylic acid during rootstock formation phase. The experiment was conducted in a greenhouse, using the randomized block design in a 5 × 5 factorial arrangement, which consisted of five values of electrical conductivity of water - ECw (0.6, 1.5, 2.4, 3.3, and 4.2 dS m-1) and five concentrations of salicylic acid (0, 0.8, 1.6, 2.4, and 3.2 mM L-1), with four replicates, and two plants per plot. Salicylic acid up to 1.3 mM L-1 increased the relative water content and decreased electrolyte leakage in the leaf blade of ‘Paluma’ guava seedlings. Foliar application of salicylic acid at a concentration of 1.7 mM L-1 attenuated the effects of salt stress on chlorophyll a of guava seedlings irrigated with water of up to 1.6 dS m-1. The deleterious effects of salt stress on carotenoid concentration and quantum efficiency of photosystem II were not attenuated by the application of salicylic acid.
