“…Hydrogen peroxide acts as a metabolic signal and, as such, it is capable of triggering reactions related to the mitogen-activated protein kinase (MAPK) pathway, thus inducing tolerance to different stresses in plants through the expression of genes associated with the defense system (Saxena, Srikanth, & Chen, 2016). The effect of hydrogen peroxide on crops under salt stress, either via seed pretreatment or foliar spray, has been studied in crops such as maize (E. M. da Silva, Lacerda, Medeiros, Souza, & Pereira, 2016), passion fruit (Silva et al, 2021b), and soursop (Veloso et al, 2021;A. A. R. da Silva, Capitulino, Lima, Azevedo, & Veloso, 2021a).…”

Saline water has been used in irrigation due to the limited availability of fresh water, especially in arid and semi-arid regions. However, the use of this type of water can affect crop growth and development. Studies have tested the use of chemical conditioners to minimize the negative effects of salinity on plants. In this scenario, the present study examined the role of hydrogen peroxide in mitigating the negative effects of salt stress on zucchini plants grown in a hydroponic system. The study was carried out in a greenhouse in Pombal - PB, Brazil. The NFT (nutrient film technique) hydroponic system was employed. A randomized complete experimental design was set up with a 4 × 4 factorial arrangement consisting of four levels of electrical conductivity in the nutrient solution (ECns: 2.1 [control], 3.6, 5.1, and 6.6 dS m-1) and four concentrations of hydrogen peroxide (H2O2: 0, 20, 40, and 60 μM), in three replicates. Foliar spraying with H2O2 at 60 and 40 μM associated with the nutrient solution of 2.1 dS m-1 increased stem diameter and root length, respectively, at 47 days after transplanting. However, at ECns higher than 2.1 dS m-1, the application of H2O2 at the concentrations of 60 and 40 μM intensified salt stress, reducing stem diameter and root length. Nutrient solution salinity levels above 2.1 dS m-1 reduce photosynthetic pigments; the number of leaves; leaf area; the length of the main branch; and the dry biomass of stems, leaves, and roots of zucchini plants. Chlorophyll b and carotenoid contents are the variables most sensitive to changes in salinity levels.

“…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.…”

“…Although several studies address the effects of salt stress on passion fruit (Lima et al, 2021;Sá et al, 2021;Silva et al, 2021), the tolerance of this crop to salinity varies according to crop development stage (Soares et al, 2021). In this context, the objective of this 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 in the second year of its cultivation.…”

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.

“…A alta concentração de sais presentes no solo e na água de irrigação é um dos principais fatores limitantes para a produção agrícola nas regiões áridas e semiáridas, influenciando no baixo rendimento produtivo das plantas cultivadas (LIMA et al, 2021;SILVA et al, 2021). Em cultivos sob condições salinas, as plantas sofrem redução no seu desenvolvimento, crescimento e produtividade, decorrente dos íons presentes na solução do solo, ocasionando distúrbios funcionais dos quais prejudicam o metabolismo vegetal (DINIZ et al, 2021;FREIRE e NASCIMENTO, 2018).…”

The yellow passion fruit (Passiflora edulis f. flavicarpa Degener) crops have been gaining notoriety in Brazil, whose cultivation extends to almost all regions. The aim of this study was to evaluate the growth of yellow passion fruit seedlings in response to the interaction between substrate composition and irrigation water salinity levels. The experimental trial was installed in a randomized block design, with a factorial scheme (3x6) consisting of two factors: three levels of salinity and six types of substrates, distributed in four replications, each plot consisting of a polyethylene bag composed of two plants. The factor levels of salinity, electrical conductivity: 0.3, 1.2 and 2.1 dSm-1 did not influence the physiological growth and development of the seedlings, the substrates resulted in statistically significant effects, the cattle manure presented the highest percentage in levels of physiological growth and development of the plant.
