“…In addition, this effect on the pigments confirms the predominance of the osmotic effect because there was no effect on the contents of carotenoids, which are components considered as protectants, and tend to be high when there is a more severe stress condition, as observed by Sá et al (2017) in citrus plants. In this study, there were no effects of N doses on the contents of pigments; these results do not agree, partially, with those of Vieira et al (2010), who found increment in chlorophyll a but not in chlorophyll b, studying the effect of four N concentrations, through the addition or not of ammonium sulfate, on 'Pérola' pineapple plants.…”

The study aimed to evaluate the mitigating effect of nitrogen (N) on the damages caused by irrigation water salinity, in the production of yellow passion fruit seedlings. A randomized block design in split plots was used, with five levels of irrigation water salinity (plot) (0.3, 1.0, 1.7, 2.4 and 3.1 dS m-1) and five doses of N fertilization (sub-plot) (180, 240, 300, 360 and 420 mg of N dm-3), with five replicates, totaling 125 experimental units, with one plant per plot. The seedlings were produced in 3.780 mL tubes, used as drainage lysimeter, which received a daily irrigation depth based on water balance. Growth and contents of chlorophyll and carotenoids were evaluated at 85 days after sowing. The increase in irrigation water salinity reduced stem diameter, plant height, number of leaves, chlorophyll a, chlorophyll b and total chlorophyll; increasing N doses also led to linear decline in stem diameter and plant height. Application of increasing doses of N did not attenuate the effect of salinity on growth and pigment contents.

“…The increase of the biomass allocation in the "hard" jackfruit ( Figure 2B), may be an adaptation to the saline conditions imposed, since there is variability between varieties of the same species (PEREIRA et al, 2017;SÁ et al, 2017). As a defense mechanism, some varieties maintain high levels of potassium (K + ) and calcium (Ca 2+ ) and low sodium content (Na + ) in its tissues, thus absorbing higher amounts of K + + and Ca +2 , in order to maintain high K + /Na + and Ca 2+ /Na + ratios, so their biomass are not reduced even under saline conditions (GALDINO et al, 2017).…”

“…These authors also state that root system inhibition occurs as a plant strategy to avoid contact with the salt present in the substrate. Most fruit trees present a detrimental effect on root growth with increased salt levels in the irrigation water, such as lemon (SÁ et al, 2017), papaya (LIMA NETO et al, 2016) and guava (OLIVEIRA et al, 2018).…”

The salinity is one of the agriculture main obstacles worldwide, limiting plant growth and development. However, the use of biofertilizers can be a viable alternative to mitigate the effect of salinity. In this way, the aim of this study was to evaluate the effect of irrigation water salinity on two jackfruit varieties seedlings formation under the application of common and enriched bovine biofertilizers, respectively. In that sense, an experiment was carried out in a greenhouse in the period of october/2016 to february/2017, in the Federal University of Paraiba (FUPB), in the county of Areia, Paraiba state, Brazil. The substrate was collected from the 10 cm depht of a Distrophic Regolithic Neossol. The experimental design was completely randomized (DCR), in factorial scheme 5x3x2, with three replications, referring to the electrical conductivity levels of the irrigation water (0.5; 1.0; 2.0; 3.0 and 4.0 dS m -1 ), two types of biofertilizer (common biofertilizer; enriched biofertilizer; absence of biofertilizer) and two jackfruit varieties (soft and hard jackfruit), packed in black polyethylene bags with a maximum capacity of 3.0 kg, totaling 90 treatments. The biofertilizer was diluted in non-saline water in the proportion of 1:3, it was applied only once to 10% of the volume of substrate, days two before sowing. The studied variables were -leaf area (LR); root area (RA); root diameter (RD); biomass allocation (BA); root dry mass (RDM); dry mass of aerial (AP) part and total dry mass (TDM). Biofertilizers did not inhibit but positively attenuate the harmful effects of excessive salt content in the irrigation water on jackfruit phytomass production. The growth and development of the jacfruits seedlings was positively expressed in the treatments with rich and common biofertilizer, respectively.A salinidade é um dos principais entraves em todo mundo, constituindo-se num dos fatores limitantes ao crescimento e desenvolvimento das plantas. No entanto, o uso de biofertilizantes pode ser uma alternativa viável para mitigar o efeito da salinidade. Deste modo, objetivo deste estudo foi avaliar os efeitos da salinidade da água de irrigação sobre a formação de duas

“…These authors still denote that the inhibition in the root system of the plant occurs as a strategy to avoid contact direct with the salt in the substrate. The majority of fruits presented a detriment in growth with increased salts in the irrigation water, such as lemon-Citrus limon (Sá et al, 2017), papaya (Lima Neto et al, 2016) and guava-Psidiun guajava (Cavalcante et al, 2010).…”

The salinity is considered one of the main obstacles to agriculture worldwide, constituting one of the limiting factors to the growth and development of the plants. The objective of this study was to evaluate the effects of salinity of irrigation water in the formation of seedlings two varieties of jackfruits, and with the application of common bovine biofertilizer and chemically enriched bovine biofertilizers. In this sense, an experimente was carried in greenhouse conditions, in the period from October 2015 to February 2016, in Areia County, Paraiba State, Brazil. The substrate used was a material collected of the first 10 cm of depth of a Dystrophic Regolitic Entisol. The experimental design was completely randomized in a factorial scheme 5 × 3 × 2, corresponding to levels of irrigation water saline of 0.5; 1.0; 2.0; 3.0 and 4.0 dS m-1, in soil without and with common bovine biofertilizer and enriched biofertilizer, tested with two varieties of jackfruit (jack-soft and jack-hard), and with six replicates. The biofertilizer after dilution in non-saline water (0.5 dS m-1), in proportion of 1:3, where was applied once to 10% of the substrate volume, two days before sowing. The increment of irrigation water salinity inhibited alls variables studied in the jackfruits plants, but with less intensity in the treatments with bovine common biofertilizer.
