“…This reduction in passion fruit root growth with the increase in ECw can be attributed to the decrease in water absorption evidenced by the TWC and, therefore, it tends to affect the growth and development of the different plant parts, SDM ( Figure 4B) and RDM ( Figure 5A). Similar results were observed by Oliveira et al (2015) in P. edulis seedlings due to the increase in irrigation water salinity. These authors reported reductions of 65.8% in RDM as ECw increased from 0.3 to 3.5 dS m -1 .…”

“…Based on the results of Figure 3A, there was a reduction of 2.64% in stem diameter per unit increase in water salinity, which corresponds to a decrease of 11.66% between plants irrigated with water of highest and lowest saline levels. This behavior is due to the reduction in the absorption of Oliveira et al (2015), who found reductions of 11.08% in the SD of P. edulis due to the increment in ECw from 0.3 to 3.5 dS m -1 . Figure 3B shows the linear reduction of 4.48% in the total water consumption per unit increase in the electrical conductivity of the irrigation water (ECw).…”

“…The tolerance of crops to salinity, despite varying among species, genotypes, development stages, types of salts, nature and intensity of the stress (DIAS; BLANCO, 2010;SÁ et al, 2013;OLIVEIRA et al, 2015), can be evaluated through the capacity of the plant to tolerate levels of salts without losses in growth and production. Hence, various studies have evaluated the behavior of passion fruit cultivars in the search for viable alternatives to cope with salinity in semi-arid regions (LEITE et al, 2015).…”

ABSTRACT:The genus Passiflora of the passion fruit crop is the most important from economic point of view. However, its cultivation in the semi-arid region is at risk due to salinity problems, requiring the identification of tolerant species, which develop better in environments with salinity problems. The objective of this study was to evaluate the effects of water salinity on growth and formation of seedlings of three species from the genus Passiflora. The treatments were distributed in a completely randomized design, adopting a 5 x 3 factorial arrangement, with five levels of irrigation water salinity (ECw) of 0.3; 1.4; 2.5; 3.6 and 4.7 dS m -1 and three species of Passiflora: gibertii; cincinnata and edulis 'BRS Gigante Amarelo', with four replicates. P. edulis surpassed the others in leaf area, shoot, root and total dry matter and Dickson index of seedling quality. Irrigation water salinity inhibits the formation of seedlings evaluated by growth in height, stem diameter and shoot, root and total dry matter of the studied species of Passiflora. The interaction between ECw and the Passiflora species interfered significantly in height, root, shoot and total dry matter and Dickson quality index. ECw above 0.3 dS m -1 affects the Dickson quality index of P. gibertii more,compared with P. edulis and P. cincinnata.

“…Oliveira et al (2015a) afirmam que a partir da condutividade elétrica de 1,5 dS m -1 o aumento da concentração de sais de sódio no substrato exerce fitotoxicidade às plantas de maracujazeiro desencadeando um conjunto de alterações iônicas e hormonais comprometendo o crescimento das plantas (SÁ et al, 2013).…”

A aplicação de biofertilizantes de esterco fresco de gado bovino pode atenuar os efeitos negativos do excesso de sais na germinação das sementes e crescimento inicial das plantas. Nessa direção, foi desenvolvido um experimento em abrigo telado do Centro de Ciências Agrárias, Universidade Federal da Paraíba, município de Areia-PB, para avaliar os efeitos de biofertilizantes durante a formação de mudas de maracujazeiro amarelo irrigadas com água salina. Os tratamentos foram organizados em esquema fatorial 2 x 3 x 5, referente à salinidade da água de irrigação (0,43 e 4,5 dS m<sup>-1</sup>), no substrato sem e com biofertilizantes (comum e quimicamente enriquecido) nas concentrações de 0,0; 2,5; 5,0; 7,5 e 10,0%, diluído em água não salina. As épocas de aplicação dos biofertilizantes foram uma dia antes da semeadura e aos 15, 22, 29 e 36 dias após a emergência das plântulas (DAE), em um volume de 250 mL por aplicação. Foi adotado o delineamento de blocos casualizados com cinco repetições. Aos 60 DAE avaliaram-se o crescimento em diâmetro caulinar e altura da haste principal, número de folhas e área foliar, biomassa seca das raízes, caule e folhas. Os dados foram submetidos a análise de variância e as médias comparadas pelo teste de Tukey (p ≤ 0,05). Os biofertilizantes nas concentrações utilizadas não inibiram a ação degenerativa do aumento da salinidade da água no crescimento em diâmetro do caule, altura da haste principal e na formação de biomassa das raízes, caule e folhas das mudas de maracujazeiro amarelo.

“…However, works that seek the production of formulations of alternative substrates for the production of seedlings, seeking mitigation of the effect caused by the saline stress in the culture of the passion fruit plant are scarce (Oliveira et al, 2015), which it would be an alternative for the producer as cost reduction and use of salty water. In this context, it was aimed at with this work to evaluate the production of seedlings of yellow passion fruit plant submitted to different substrates and different saline waters.…”

In the process of production of seedlings the formulation of substrates that supply the nutritional needs and make available appropriate humidity tenor is relevant for the success and the reduction of costs of the producing with other inputs. In this perspective, it is known that alternative substrates are rich in organic matter, which possesses extenuating action for the harmful effect of the salinity. Therefore, it was aimed at to evaluate the effect of saline waters and formulations of substrates in the production of seedlings of yellow passion fruit plant. Experiment was driven in atmosphere protected in the dependences of the Federal University of Campina Grande, Pombal, Paraíba. The randomized block design was used in factorial outline 5 × 5, being five levels of salinity of the irrigation water (0.3; 1.3; 2.3; 3.3 and 4.3 dS m -1 ) and five substrates: S1 = soil; S2 = soil, goat manure and bovine manure (1:1:1); S3 = soil and goat manure (3:1); S4 = soil and bovine manure (3:1); S5 = soil, goat manure and bovine manure (3:0.5:0.5). To the 52 days after the sowing the growth analyses and quality of the seedlings were checked. The growth of the passion fruit plant seedlings was inhibited by the salinity in the irrigation water. However, the use of organic inputs in the formulation of the substratum lessens the harmful effect of the saline stress, being the best substratum, soil and bovid manure in the proportion 3:1.
