Abstract We carried out greenhouse experiment to evaluate the effect of silicon (Si) on growth and mineral nutrition of yellow passion fruit (Passiflora edulis) submitted to saline stress in a nutritive solution. The experiment comprised a completely randomized design in a 5x4 factorial scheme: five NaCl concentrations (0; 7.5; 15; 30 and 60 mmol L-1) and four SiO2 concentrations (0; 0.5; 1.0 and 1.5 mmol L-1) with four replicates. At the end of 35 days, we measured stem diameter, leaves, stem, and roots dry matter, as well as the macronutrient, Na, Cl, and Si leaf accumulation in plants. In most cases, the increase in NaCl supply in a nutritive solution reduced the dry matter of roots, stem, and leaves. The SiO2 supply attenuated the effect on higher tested saline stress (30 and 60 mmol L-1 NaCl) on roots and stem dry matter. The application of 0.5 mmol L-1 of SiO2 reduced the deleterious effect of salinity on all macronutrients absorption in yellow passion fruit cultivated in a nutritive solution.

Among the factors that contribute to better initial development of plants, it is the substrate used. Therefore, this study aimed to evaluate the effect of substrate in initial formation and morphology of the roots of two species of passion fruits. The analyses were done in the nursery of the Federal University of Goiás (UFG), Regional Jataí, Brazil, with a light interception of 60%. The material used were seeds of yellow passion fruit (Passiflora edulis f. flavicarpa) and the cultivar FB 200 (Flora Brasil), harvested in the UFG experimental field. They were sown in three types of substrates: Soil I (mixture of soil, chicken manure and sand in a ratio of 2:1:1 by volume), soil II (steep bank), and Bioplant®, using for plants perforated bags with a capacity of 1.5 L. The experimental design was a completely randomized design with six treatments, eight replications and four plants per plot. After 30 days of sowing, fresh matter of root, root dry matter and morphology were evaluated. The substrate affected the initial development of yellow passion fruit, obtaining the best results with Bioplant®, showing as promising for the development of all the evaluated characteristics.

This study aimed to evaluate different substrates to produce yellow passion fruit seedlings. For this purpose, an experiment was carried out in a greenhouse, from April to June 2016. A completely randomized design with five replications, in a 6 x 5 factorial scheme was used. The first factor was the alternative substrates (poultry, cattle and equine manure, sugarcane and coconut bagasse, and Organomais compost). The second factor was the replacement levels to the commercial substrate of Plantmax® (100:0, 75:25, 50:50, 25:75, 0:100). The seedling evaluation was carried out 42 days after sowing. The following variables were analyzed: length, width, and the number of leaves; plant height and shoot dry matter. A significant effect (P0.05) for the interaction between the factors was verified. The addition of 60% cattle manure and Organomais to the commercial substrate Plantmax® promoted greater length, width, and the number of leaves, plant height, and shoot dry matter accumulation in the yellow passion fruit seedlings.

An investigation was undertaken to determine the fruit and juice metric traits of fresh fruits obtained from two yellow passion fruit genotypes grown in south-eastern Nigeria in two seasons. The passion fruit genotypes (Conventional and KPF-4) received 0, 10, 20, 30, 40 t ha-1 poultry manure (PM) rates in 2014 and 0, 10, 20 t ha-1 PM, 5 t ha-1 PM + 200 kg ha-1 NPK 15:15:15, 10 t ha-1 PM + 200 kg ha-1 NPK and 400 kg ha-1 NPK in 2016. Ten ripe and freshly dropped fruits in 2015 and 2017 were picked and taken to the laboratory. Fruit and juice metric traits (such as fruit length, circumference, pulp weight, juice volume and weight) were measured. Data collected were subjected to analysis of variance following the procedure for split-plot experiment in completely randomized design. KPF-4 significantly (p<0.05) produced longer, wider and heavier fruits than the Conventional in 2015 whereas in 2017 all the fruit metric traits did not significantly (p>0.05) differ between the genotypes. Juice volume (682 ml) and pulp fresh weight (942 g) in 2015 were significantly highest in the Conventional when they received 20 or 40 t ha-1 PM. Application of 10 t ha-1 PM + 200 kg ha-1 NPK in 2016 enhanced the production of highest juice volume (723 ml) and pulp fresh weight (770 g) in the Conventional. Juice percentage and fruit metric traits of yellow passion fruit could be enhanced with the application 20 t ha-1 PM, considering lesser cost of PM procurement, or combined application of 10 t ha-1 PM + 200 kg ha-1 NPK.

Obtaining vigorous, quality seedlings is a complex task because it involves multiple physical, chemical and biological factors, with the substrate being a fundamental of this process. Therefore, this study proposes to evaluate different formulations of substrate mixtures and identify which provides better emergence vigor and shoot and root growth in passion fruit (Passiflora edulis Sims). The experiment was laid out in a completely randomized design consisting of 23 substrates with different proportions of Vivatto® and Osmocote®, washed sand, soil, fine coal, coarse coal, enriched hydrogel and enriched vermiculite, with and without the addition of NPK, which were distributed into four replications of four plants per plot. To enrich the hydrogel and vermiculite, foliar fertilizer was used. Emergence vigor was evaluated throughout the seedling emergence period and seedling growth parameters were observed at 60 days after sowing. The data were subjected to multivariate analysis and the groups formed were subjected to analysis of variance. Based on principal component analysis (PCA), four groups were identified. The group composed only of soil + coarse coal and enriched hydrogel (2:2:1) was considered the best treatment, as it favored most of the vegetative growth and emergence vigor traits. Soil plus sand with the addition of NPK was not recommended to grow passion fruit seedlings in any of the proportions used, as there was no emergence.

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.

Yellow Passion Fruit

Brazil is the world&rsquo;s largest producer and largest consumer of passion fruit, producing approximately 0.1 million tons. However, crop management techniques are deficient in the use of alternative sources of fertilizer, an extremely relevant aspect in reducing production costs, as some nutrients are imported at high costs. Thus, this study was intended to calculate the percentage of an optimal dose of sewage sludge according to the regression model for each morpho-agronomic trait of yellow passion fruit. A completely randomized design (CRD) was adopted, consisting of four treatments, 0; 25; 50; and 75%, with 20 replicates considering one plant per replicate. Treatments were T1 (0 without sewage sludge addition), T2 (75% soil + 25% sewage sludge); T3 (50% soil + 50% sewage sludge); and T4 (25% soil + 75% sewage sludge). Regression coefficients were above 80%. Morpho-agronomic traits obtained optimal doses at a concentration of 50% of sewage sludge for the manufacture of the substrate. The conclusion reached was the substrate based on sewage sludge in the proportion of 50% combined with 50% of soil was superior to the other ones for seedling production.

Abstract The seminiferous propagation of Sour Passion Fruit (Passiflora edulis Sims) is the main kind of multiplication due to the ease formation of seedlings. However, the reduced number of productive and homogeneous cultivars reflects the need for genetic breeding. The objective of this study was to assess the maternal and reciprocal effects in vigor and germination of Sour Passion Fruit seeds. The experiment was conducted in a completely randomized design in the factorial scheme, with two structure (hybrid and reciprocal) and ten crosses with four replicates (50 seeds) in trays containing inert sand in germination chamber. Before sowing, it was obtained the weight of 100 seeds, and at 28 days germination percentage, emergence speed index, total seedlings length, shoot length and main root length, number of normal seedlings and dry mass per seedlings were evaluated. The reciprocal effects tell us which genotype is most promising when used as the female or male parent for the trait studied. It can be inferred that there is maternal effect influencing the weight of 100 seeds, emergence, emergence speed index and the number of normal seedlings. There was influence of the parent on the expression of traits in seeds of Sour Passion Fruit. It is important to define the paternal and maternal parent to obtain seeds with high germination potential.

ABSTRACT The knowledge concerning the physiology of germination in saline areas may contribute to the development of more efficient cultural practices and adequate choice of planting areas. Thus, the objective of this study was to evaluate the effects of saline and temperature stress on germination and vigor of Piptadenia moniliformis (a species known in Brazil as "catanduva") seeds. The treatments were distributed according to a completely randomized design in accordance with a 3 x 6 factorial arrangement (temperature x osmotic potential), with four replicates of 25 seeds each. The seeds were put to germinate at constant temperatures of 25, 30, and 35 °C on paper towel moistened in distilled water (0.0) and NaCl solutions at 0.2, 0.4, 0.6, 0.8 and 1.0 MPa. The results were evaluated in terms of germination percentage and germination speed index, seedling (root and shoot) length, and total dry matter. P. moniliformis seeds were able to germinate under temperatures of 25 and 30 °C and tolerate osmotic potentials of up to -0.6 MPa; from this point on, there is progressive decrease in the physiological quality of seedlings.

Abstract Yellow passion fruit are highly perishable after harvest. Organic products may have better nutritional quality and better postharvest conservation due to the application of different cultural practices such as organic fertilization and non-use of synthetic pesticides. The objective of this study was to evaluate the effects of organic fertilization on the quality and postharvest conservation of yellow passion fruit. The orchard was installed in a completely randomized design with four replications and four plants on the same row per experimental unit. The treatments were three types of fertilization applied in the orchard: mineral (MIN) recommended for the crop; organic (ORG), equivalent to the recommended potassium fertilization for the crop and 2 × ORG with twice the ORG dose. The organic fertilizer used was partially cured cattle manure. The mineral and organic fertilizers were applied superficially. During the harvest, the fruits were classified according to mass, type A (above 175 g), B (between 125 and 175 g) and C (below 125 g). The experiment was developed in a completely randomized design, in a factorial scheme (fertilization x fruit mass classes), with six replications and 90 fruits per treatment. Fruits of plants fertilized with 2 × ORG showed the same pulp yield (PY) of those that received MIN fertilization. Fruits of class C and fruits from plants fertilized with MIN showed greater weight loss. No difference between fertilization and mass classes was found for soluble solids (SS) and titratable acidity (TA). There was also no effect of fertilization on the SS / AT ratio, pH and vitamin C content, however, class B fruits showed, on average, higher values for these pulp aspects. The dose of ORG fertilizer was not enough to keep the fruit quality in relation to the PY, but the fruits from plants fertilized with ORG and 2 × ORG kept up with better commercial quality for a longer period. The organic fertilizer with cattle manure is an efficient alternative to maintaining postharvest conservation of yellow passion fruit.
