“…Guava (Psidium guajava L.) is among the most commercially exploited fruit crops throughout Brazil, due to the various possibilities of use, as it can be consumed fresh or processed as guava paste, jams, fruit in syrup, puree, base for beverages, soft drinks, juices, and syrups (Onias et al, 2018). Despite the importance of this fruit crop for the Northeast region, the climate characteristics, such as rainfall irregularities, high temperature, and high evapotranspiration rates, have posed limitations to obtaining a high yield, which has made irrigation practice indispensable (Silva et al, 2018;Lima et al, 2022). Besides this, the high concentrations of salts in water sources are obstacles to the expansion of irrigated agriculture (Souza et al, 2016).…”

“…The presence of salts in water and, or, soil triggers changes in the plant that begins by the reduction in the osmotic potential of the soil solution, restricting the absorption of water and nutrients, in addition to causing toxic effect of specific ions, such as sodium and chloride, which triggers nutritional imbalance/impacts (Bezerra et al, 2018a;Andrade et al, 2019). It should be considered that the effects of salt stress vary between species, cultivars, and edaphoclimatic conditions (Lima et al, 2022). Among the cultivation strategies that can increase the tolerance of plants to salt stress, the use of grafting stands out (Zhang et al, 2018).…”

The availability of water with low electrical conductivity for irrigation in the Northeastern semi-arid region is one of the limiting factors for the expansion of irrigated agriculture. Thus, it is necessary to use waters with high electrical conductivity, requiring the search for strategies to reduce the negative impacts of salts on plants. In this context, the objective of this study was to evaluate the morphophysiology and production of guava cv. Paluma subjected to irrigation with saline waters and foliar application of salicylic acid after grafting. The experiment was conducted under greenhouse conditions in Campina Grande - PB, Brazil, in a randomized block design, adopting a 2 × 4 factorial scheme, with two values of electrical conductivity of irrigation water - ECw (0.6 and 3.2 dS m-1) and four concentrations of salicylic acid (0, 1.2, 2.4 and 3.6 mM), with three replicates. Irrigation with water of 3.2 dS m-1 reduced gas exchange, rootstock and scion diameters, crown diameter and volume, vegetative vigor index, polar and equatorial diameters of fruit, number of fruits, mean fruit weight, and fresh fruit weight of fruits of guava cv. Paluma. Salicylic acid application up to 3.6 mM did not mitigate the effects of salt stress on grafted guava cv. Paluma, at 390 days after transplanting.

“…This increase was due to photosynthesis because, at the highest concentration of pyruvate and at the highest salinity, the stomata did not close. It should be noted that one of the main mechanisms that plants use to reduce water loss in such situations is stomatal closure (Lima et al, 2022), which is indicative, in this study, of salinity mitigation effects by pyruvate.…”

Although the semi-arid region of Northeast Brazil is a major producer of yellow passion fruit, the problems of salts in the soil and water sources, in many areas have limited the growth and production of this crop, which highlights the importance of studies aimed at reducing such effects. In this context, the objective of this study was to evaluate the effect of foliar application of pyruvate, as a mitigator of salt stress, on the morphophysiology of yellow passion fruit, in seedling phase. The treatments consisted of three electrical conductivities of irrigation water (ECw: 0.8, 2.4, and 4.0 dS m-1) and three concentrations of pyruvate (0, 25, and 50 mM), distributed in a randomized block experimental design in a 3 × 3 factorial scheme, with four replications and two plants per plot. Irrigation with ECw of 4.0 dS m-1 reduces growth variables, phytomass, Dickson quality index, and increases electrolyte leakage in passion fruit seedlings cv. Redondo Amarelo. Exogenous application of calcium pyruvate (25 and 50 mM) increased growth, phytomass, Dickson quality index, relative water content and leaf succulence and reduced electrolyte leakage in the leaf blade in passion fruit. Exogenous application of pyruvate attenuates salt stress, with beneficial effects on CO2 assimilation rate, transpiration, instantaneous carboxylation efficiency, intrinsic water use efficiency, and root dry mass.

“…Despite the production potential of soursop for the Northeast region, one of the limitations to its production system is the occurrence of low rainfall and high evapotranspiration in most months of the year [ 3 ]. In addition, the water sources commonly used in irrigation have high concentrations of salts [ 4 , 5 ].…”

Hydrogen peroxide at low concentrations has been used as a salt stress attenuator because it induces a positive response in the antioxidant system of plants. This study aimed to assess the gas exchange, quantum yield, and development of soursop plants cv. Morada Nova grown with saline water irrigation and foliar hydrogen peroxide application. The experiment was carried out under greenhouse conditions using a randomized block design in a 4 × 4 factorial scheme corresponding to four levels of electrical conductivity of irrigation water, ECw (0.8, 1.6, 2.4, and 3.2 dS m−1), and four doses of hydrogen peroxide, H2O2 (0, 10, 20, and 30 μM), with three replicates. The use of irrigation water with electrical conductivity above 0.8 dS m−1 inhibited stomatal conductance, internal CO2 concentration, transpiration, maximum fluorescence, crown height, and vegetative vigor index of the Morada Nova cultivar of soursop. Compared to untreated plants, the hydrogen peroxide concentration of 30 μM resulted in greater stomatal conductance. Water salinity of 0.8 dS m−1 with hydrogen peroxide concentrations of 16 and 13 μM resulted in the highest variable fluorescence and quantum efficiency of photosystem II, respectively, of soursop plants cv. Morada Nova at 210 days after transplantation.
