“…With respect to the two passion fruit varieties, statistically significant differences (p < 0.05) were also observed for all the variables, except for stem and root dry weight. Similar results have been reported for the same variables, in seedlings of different crops, caused by water electrical conductivity (Sá et al 2013, Bezerra et al 2016, Souza et al 2018. The increase in water salinity prompted a 42.28 % linear decline in the average plant height of Figure 1.…”

“…Salt tolerance varies substantially in seedlings, even among genotypes of a same species, as observed in the two passion fruit varieties studied here (BRS GA1 and BRS RC) and by other authors (Sá et al 2013, Bezerra et al 2016, Moura et al 2017, Souza et al 2018 in different crops. According to Taiz & Zeiger (2013), salt stress can cause a nutrient and physiological imbalance that directly influences the conversion of carbon assimilated by plants, promoting a reduced growth and biomass accumulation, which may vary between varieties of a same species.…”

The use of salt water in irrigation can reduce the growth and yield of agricultural crops. This study aimed to assess the germination, emergence, physiology and growth of passion fruit seedlings of two varieties under salt water irrigation. The study was conducted in two stages: the first carried out in a laboratory and the second in a greenhouse, using a randomized block design, in a 2 x 4 factorial scheme, corresponding to two passion fruit varieties (BRS RC and BRS GA1) and four levels of irrigation water electrical conductivity (0.2 dS m-1, 2.2 dS m-1, 4.2 dS m-1 and 6.2 dS m-1), with four replications. The BRS GA1 variety exhibited the highest germination index and rate, in the germination stage, despite being more sensitive to salinity than the BRS RC. There was no damage to the photosynthetic apparatus in the BRS GA1 seedlings during growth, as demonstrated by the higher leaf biomass, when compared to the BRS RC variety.

“…In the Brazilian semi-arid region, salinization affects about 30% of the soils in irrigated perimeters (CODESVASF, 2021). In view of this, research has shown that there are salinitytolerant plants and that the proper management of this type of water can become an option for regions with scarcity of good quality water (DIAS, 2016), since the lack of knowledge about the use of salinized water in agricultural cultivation generates negative consequences, such as crop loss and damage to soils in irrigated areas (OLIVEIRA et al, 2019;SILVA et al, 2018;SOUZA et al, 2018;).…”

The aim of this study was to evaluate the salinity tolerance of alfalfa varieties, aiming at their inclusion in production systems that use water with high levels of salts for irrigation or saline soils. The experiment was conducted in a greenhouse, in a 3x5x3 factorial scheme, three alfalfa varieties (LE-N4, Crioula and DK-192), five salinity levels (0; 3.5; 5.0; 7.0; 10 .5 and 14.0 dS m-1) and three shoots of the aerial part, with four repetitions. For irrigation management, lysimeters were installed. Fresh and dry aboveground and root biomass, chlorophyll, water use efficiency and enzymatic activity were analyzed. The increase in salinity reduced fresh and dry aboveground and root biomass, chlorophyll and water use efficiency. Salinity altered the biochemical responses of the evaluated varieties. DK-192 showed higher production of fresh and dry aboveground biomass. LE-N4 was more sensitive to salt stress, significantly reducing production from a salinity level of 7.0 dS m-1. The increased catalase activity for Crioula and DK-192 under salt stress conditions contributed to the higher production of fresh and dry aboveground biomass.

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.
