The salinity is one of the stresses that more limits the income of the agricultural cultures, mainly in areas semiarid as the Northeast, though, it is known that the biostimulants are substances capable to alter the metabolism of the plant and to favor development under adverse conditions of stresses. In this context, it was aimed at with this work to evaluate the initial growth of the passion fruit plant irrigated with saline water and the application of biostimulants. The experiment was conducted at the Federal University of Campina Grande, campus Pombal, in factorial outline 5 × 3, corresponding to five salinity levels (S1 = 0.3; S2 = 2.3; S3 = 3.3; S4 = 4.3 and S5 = 5.3 dS m-1) and two biostimulants (B1 = Acadian and B2 = Crop Set) and treatment testifies (without an application of biostimulant). The dose used for each product was 4 ml L-1 of Acadian and 3 ml L-1 of Crop Set. It was used seeds of the passion fruit of the variety BRS-giant, sowed in containers of black polypropylene of 400 ml, containing sand and substrate Carolina Soil, in the proportion 1:1. For the 32 days after the sowing was determined the height, the root length, the fresh and dry mass (aerial, root and total) of plants, the biomass production and the index of tolerance the salinity. The data were submitted to the variance analysis of the test F at the level of 5% of probability, and when significant, the averages were submitted to the test Tukey for both factors, saline levels and biostimulants. The use of vegetable biostimulants increases the initial growth of the yellow passion fruit plant. The salinity in the irrigation water attacks the growth, however, I use of the biostimulant Crop Set lessens the harmful effect in passion fruit seedlings.

Hydrogen peroxide (H2O2) is a molecule that can flag plants under biotic and abiotic stress conditions. Among the kinds of stress, the salinity stress is the one that most usually affects plants. Consequently, the purpose hereof was to use hydrogen peroxide (H2O2) to mitigate the possible harmful effects of salinity in yellow passion fruit seedlings. We employed a randomized block design, in a 5 × 3 factorial scheme, corresponding to five irrigation water electric conductivity levels (0.3; 1.3; 2.3; 3.3; and 4.3 dS m-1) and three hydrogen peroxide concentrations (0; 5; and 15 μmol L-1), with four repetitions. The treatments were applied foliarly 7 and 15 days after the seedlings’ germination with hand sprayers. Sixty days after sowing, we evaluated the seedlings’ growth and quality variables, which finally proved that hydrogen peroxide mitigates the harmful effect of the irrigation water’s salinity up to 2 dS m-1 in the growth of yellow passion fruit seedlings at the concentration of 5 μmol/L. Nonetheless, excessive concentrations (15 μmol L-1) associated with high salt concentrations were proven detrimental to the seedlings’ phenological growth and quality.

ABSTRACT Saline irrigation water at high levels causes disturbance in the growth of more sensitive plants. The objective of this research was to evaluate the initial growth of Pityrocarpa moniliformis seedlings under different electrical conductivity in irrigation water through physiological and biochemical analyses. The experiment was conducted in a greenhouse with five water electrical conductivities (0.5, 2.0, 4.0, 6.0 and 8.0 dS m-1) and four repetitions of 20 plants each, arranged in a randomized block design. Application of the treatments with irrigation water containing NaCl began at 30 days after sowing. To determine the behaviour of the species, the following variables were analysed: stem diameter, plant height, number of leaves, leaf area, Dickson quality index, shoot dry mass, root dry mass and total dry mass, as well as the biochemical variables, such as the concentrations of total soluble sugars, free proline and chlorophylls a and b. The increase in irrigation water salinity hampered the growth of P. moniliformis seedlings, with electrical conductivity of 0.5 dS m-1 being the limit for maximum production. The results also indicated that the deleterious effects of salt stress on P. moniliformis seedlings variables increase in concentrations of proline, total soluble sugars and betaine glycine.

Passiflora seeds germinate erratically presenting difficulties for their handling in a greenhouse. The effect of removing of basal point of seeds (RB) and pre-imbibition of seeds of sweet granadilla and yellow passion fruit in 50, 100, 200, and 400 mg mL-1 solutions of gibberellic acid (GA3) or 0.1% KNO3 solution was studied. The experiment was conducted in greenhouses in La Plata, Colombia. Two accessions PrJ1 and PrJ2 of sweet granadilla were evaluated. There were calculated the final percentage of germination (PG), mean germination time (MGT), and the mean germination rate (MGR). The leaf area and dry mass of seedlings were measured 22 days after sowing (das); with this data, specific leaf area and relation root/shoot were calculated. In all cases, the highest germination percentages were achieved treating seeds with KNO3 (89, 92, and 87% for yellow passion fruit, PrJ2, and PrJ1, respectively), but the increase in MGR (3.3 germinated seeds per day) and the decrease in MGT (16 days) were only significant for PrJ1. RB had a significant reduction of PG in all cases (28, 12, and 33% for passion fruit, PrJ2 and PrJ1, respectively). With the increase in the concentration of GA3, PG was reduced for two accessions of sweet granadilla, for yellow passion fruit this trend was not clear, no treatment with GA3 showed significant differences with the control. Leaf area (24.07 cm2) and dry mass of seedlings (135 mg) were significantly higher than seeds previously treated with KNO3 only for PrJ1.The solution of KNO3 0,1% is recommended to improve the germination and initial growth of granadilla seedlings.

ABSTRACT The study was carried out to evaluate the photosynthetic efficiency and growth of yellow passion fruit, cultivated under different levels of irrigation water salinity and exogenous application of hydrogen peroxide. The experiment was carried out in greenhouse of the Universidade Federal de Campina Grande, PB, Brazil, using drainage lysimeters with capacity for 100 dm3, filled with Entisol of sandy texture. The experimental design was randomized blocks using a 4 x 4 factorial scheme, with three repetitions, corresponding to four water salinity (0.7; 1.4; 2.1 and 2.8 dS m-1) and four concentrations of hydrogen peroxide (0, 20, 40 and 60 µM). The different concentrations of hydrogen peroxide were applied by soaking the seed for a period of 24 h and spraying the leaves on the adaxial and abaxial sides. At 35 days after transplanting, the interaction between water salinity and hydrogen peroxide concentrations did not significantly interfere with plant physiology and growth, except for the number of leaves. The hydrogen peroxide did not cause significant effects on any of the evaluated plant variables. Increasing salinity of irrigation water led to reduction in gas exchanges at 61 and 96 days after transplanting. Water salinity inhibited the CO2 assimilation, transpiration, stomatal conductance, instantaneous carboxylation efficiency and stem diameter of passion fruit plants.

Arugula is a crop of fast vegetative growth and short cycle, widely accepted worldwide. In Brazil, its production generates jobs and income for family farming. However, the use of saline water in the cultivation of this plant is one of the main factors that limit production. Given this situation, the objective of this study was to evaluate the growth of Apreciatta arugula cultivated under conditions of shading and salinity levels of irrigation water. The experiment was conducted in a greenhouse in the experimental area of the Agricultural Sciences Center of the Federal University of Alagoas, in the city of Rio Largo, AL. The treatments were obtained from the combination of two shading conditions (with shading and without shading) and five levels of electrical conductivity of the irrigation water (0.5; 2.0; 3.5; 5.0 and 6.5 dS m-1). The experimental design used was completely randomized in a 2 x 5 factorial scheme. Combined, the factors resulted in 10 treatments with four replications and one plant per plot, totaling 40 experimental units. Arugula plants were evaluated for leaf number, plant height, leaf area and dry matter of the aerial part. Increasing levels of salinity in the irrigation water, lead to a reduction in the number of leaves, plant height and dry mass of the aerial part of arugula plants cultivar Apreciatta. However, the use of shading together with the salinity of irrigation water up to 1.4 dS m-1does not affect the leaf area of arugula plants, being possible to cultivate without considerable losses.

The excess of salts may compromise the growth and physiological functions of plants, but the use of bovine organic fertilizer can mitigate these effects. It was intended was to evaluate the saline stress in soil with and without bovine organic fertilizer on the initial growth, the accumulation of biomass and the gas exchanges of the okra culture. The test was conducted at the UNILAB’s experimental farm, in Piroás, in Redenção – CE city. The treatments were distributed in a completely randomized design with five replications, in a 5 x 2 factorial concerning five irrigation water salinity levels (1.0; 2.0; 3.0; 4.0 and 5.0 dS m-1), in the presence and absence of bovine organic fertilizer. Plant height, stem diameter, root length, a dry mass of shoot, photosynthesis, transpiration and stomatal conductance were evaluated. The bovine organic fertilizer promoted better means in initial growth and biomass in okra plants compared to the control treatment, thus showing efficiency in the attenuation of the salts present in irrigation water. The increase in the saline concentration of the irrigation water reduced the gas exchange (photosynthesis, stomatal conductance and transpiration) in okra plants. Nonetheless, in smaller proportions in the soil with the bovine organic fertilizer.

Yellow Passion Fruit

The yellow passion fruit is a plant climbing botanically that has a good geographical distribution in Brazil, with more than 150 species in the country. The presence of salts in soil and irrigation water is one of the main obstacles in agriculture in the world, caused by low rainfall and high evapotranspirative rates causing the salts to accumulate in the soil. However, alternatives have been sought to try to mitigate such limitations of seedling production, such as the use of biofertilizers in the soil. In this way, the objective was to evaluate the growth and development of yellow passion fruit seedlings under the effects of irrigation water salinity and the use of bovine biofertilizer on the substrate. An experiment was carried out in a greenhouse in the Center for Agrarian Sciences and Biodiversity, from october/2017 tomarch/2018, in county of Crato-Ceara, Brazil. The substrate used was the first 20 cm material of a yellow Red Argisol. The experimental design was completely randomized design (C.R.D) in a factorial scheme 5x2, referring to the electrical conductivity values ​​of the irrigation water: 0.5; 1.0; 2.0; 3.0 and 4.0 dS m-1, in the soil without and with common biofertilizer, with three replicates. The biofertilizer, after being diluted in non-saline water (0.5 dS m-1) in the ratio of 1:3, was applied only once to 10% of the substrate volume two days before sowing. The increase in the salinity of irrigation water negatively affected the initial behavior of the passion fruit seedlings in terms of growth and development, especially in the treatments that did not receive the organic feed.

The carnauba (Copernicia prunifera [Miller] H. E. Moore) is a palm tree that has multiple uses and is of great economic and social importance for extractive families in Northeast Brazil. The objective of this work is to analyze the effect of saline water on the production of different progenies of carnauba. The experiment is arranged in a 5 x 36 factorial scheme in a randomized complete block design, with five replications and five plants per replication. The treatments consist of five levels of irrigation water salinity (with commercial NaCl levels, free of iodine: 0, 25, 50, 75, and 100 mM) and 36 free-pollination progenies. The following characteristics are evaluated: foliar length (H), collecting diameter (DC), survival rate (TS), number of leaves (NF), dry shoot mass (MSPA), dry mass of the root system (MSSR), and dry mass ratio of the root system to the shoot. The results reveal similar behavior among the progenies for the evaluated characteristics. However, significance is observed for the parameters leaf length, collection diameter, and survival rate when the progenies are subjected to salinity above 9.6 dS m-1. Another significant factor is the accumulation of Na+ in the aerial and radicular parts in salinity levels of 7.1, 9.6, and 12.0 dS m-1, with the root system being the most affected site. Thus, the tested progenies exhibit similar behaviors in tolerance to irrigation water salinity. Since the carnauba can produce seedlings in water with electrical conductivity of up to 9.6 dS m-1, this species is characterized as a bioindicator of saline soils and is recommended for planting in degraded areas.

Safflower cultivation is an alternative to tropical cropping systems, with a good rusticity and some tolerance to saline stress in some cultivars. With the increase of irrigated areas around the world, salinization of the soil is an inherent concern, being the management of irrigation and cultivated species fundamental. The objective of this study was to evaluate the growth and initial development of safflower culture submitted to irrigation water salinity levels. The experiment was carried out in a greenhouse in a completely randomized design consisting of five irrigation water salinity levels (0, 2, 4, 6 and 8 dS m-1) and six replications. The saline solution was prepared using NaCl and measured with a conductivity meter. Plant height, number of leaves and stem diameter at 26 and 41 days after emergence, and shoot dry weight were evaluated; root volume; root dry mass; total dry mass and dry root/shoot mass ratio at 41 days after plant emergence. There was no visual influence of salinity levels in the evaluations at 26 days after plant emergence. However, 41 days after plant emergence, the increase in salinity levels promoted a decrease in all analyzed variables, except for root volume. Safflower does not tolerate irrigation with saline water. The damages occur from 2 dS m-1, but the largest reductions in the initial development of safflower occur from 6 to 8 dS m-1.
