Dentro da cadeia produtiva do maracujá, na etapa de produção de mudas, um fator importante que deve ser levado em consideração é o uso da matéria orgânica na composição dos substratos, devido as diversas características benéficas que o mesmo condiciona as mudas. Nesse sentido, o presente trabalho teve o objetivo avaliar a emergência e o desenvolvimento de mudas de Passiflora edulis f. flavicarpa cultivadas em substratos com diferentes fontes de matéria orgânica. O experimento foi conduzido em casa de vegetação, em delineamento de blocos casualizados, com seis repetições e seis tratamentos, contendo cinco fontes de matéria orgânica para a composição do substrato: lodo de curtume, resíduo de torrefação de café, esterco bovino curtido, resíduo de laticínio e composto urbano, além dos tratamentos sem uso de matéria orgânica (solo com e sem adubação). Foram avaliadas características de emergência e desenvolvimento das mudas, observando-se que houve maior índice de velocidade de emergência no tratamento com resíduo de torrefação de café, além de que todos os tratamentos com fontes orgânicas apresentaram respostas satisfatórias favorecendo o desenvolvimento vegetativo do maracujá-amarelo sendo recomendadas para a produção de mudas.   Palavras-chaves: Passiflora edulis f. flavicarpa, Resíduos orgânicos, Sustentabilidade   YELLOW PASSION FRUIT PLANTLETS EMERGENCY AND DEVELOPMENT IN DIFFERENT SUBSTRATES   ABSTRACT: Brazil dominates yellow passion fruit production, supplying national and international market. In the stage of seedling production  an important factor that must be taken into account is the use of organic matter in substrates composition, due to several beneficial characteristics it brings to plantlest development. The aim of this study was to evaluate the emergence and development of Passiflora edulis f. flavicarpa grown on different substrates with organic matter sources. The experiment was conducted in a greenhouse, in randomized block design, with six treatments and (tannery sludge, coffee roasting residue, tanned bovine manure, dairy and urban compost and the control - soil with and without fertilization) six replicates,. It was evaluated the emergence and emergence characteristics of the seedlings. The results showed that there was a higher rate of emergence speed in the treatment with coffee roasting residue, besides that all treatments with organic sources presented satisfactory responses favored the yellow passion fruit vegetative development being recommended for plantlets production.   Keywords: Passiflora edulis f. flavicarpa, Organic waste, Sustainability

The use of tolerant rootstocks has shown good results in the control of Fusarium wilt in yellow passion fruit, which is considered one of the main problems in the crop as it affects the plant’s root system and has no chemical control. The present study aimed to evaluate the survival rates, the agronomic performance of the plants and the physical characteristics of the yellow passion fruit (Passiflora edulis Sims) grafted on different rootstocks in area with Fusarium wilt. The experiment was carried in Pracinha, in the State of São Paulo, Brazil, from August 2014 to May 2015, and a randomized block design was adopted, with five treatments, five replications and four plants per plot. The treatments were constituted by the following rootstocks: Passiflora alata Dryand, Passiflora gibertii N.E. Brown, Passiflora caerulea Linnaeus, double grafting P. gibertii x P. edulis and plants without grafting. The stem diameter of rootstock and the graft, the lenght of secondary branches, the number of tertiary branches, the number of surviving plants, the longitudinal and transversal diameters of the fruits, the number and mass of fruits and the productivity were evaluated. The largest diameter of the rootstock was observed in Passiflora alata while in the graft it was in plants of Passiflora edulis. The length of the secondarty branches and the number of tertiary branches were affected by the type of grafting and the rootstock used. The highest survival rates were observed in Passiflora alata (90%) and Passiflora gibertii (100%). The highest number of fruits per plant and productivity occurred in plants grafted on Passiflora gibertii. The adoption of double grafting using Passiflora gibertii x Passiflora edulis and simple grafting with Passiflora caerulea were not effective in the control of this disease. The species Passiflora gibertii and Passiflora alata showed the potential to be used as a rootstock for yellow passion fruit.

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 The interspecific introgression of resistance genes to diseases in commercial varieties through interspecific crosses has been adopted as a strategy in breeding programs of sour passion fruit. This work aimed to evaluate 11 progenies of multispecific hybrids obtained from crosses involving seven Passiflora species, in addition to four commercial cultivars, using the REML/BLUP method. The experiment was carried out as a randomized block design with six repetitions and three plants per plot. Ten fruit traits were evaluated. The additive, multiplicative, and sum of ranks indexes were applied to determine the most appropriate selective strategy in the simultaneous increase of fruit weight, number of fruits, and yield. Plants from the 325 x VAO progeny showed a lower bacterial defoliation index and better means predicted for the traits number of fruits and productivity. The progenies 325 x LD4, PL3 x LD4, and the controls CSB-Marília and BRS-Gigante Amarelo showed plants with better-predicted means for traits related to fruit quality. The genetic gains demonstrated good prospects for the use of wild species in sour passion fruit genetic breeding.

The yellow passion fruit (Passiflora edulis f. flavicarpa) needs pollinators for fructification due to the existence of mechanisms that impede self-pollinating. Pollinators of great efficiency for the yellow passion fruit in Brazil are the bumblebee species (Xylocopa frontalis, X. grisescens and X. Suspecta). Deforestation by agricultural expansion in the region has a negative impact on these pollinators’ populations, leaving space for the action of cleptobiotic species with further damage to fruit production. The objective of this study was to evaluate the frequency of pollinating bees and floral visitors during yellow passion fruit culture’s post anthesis period in Northern Paraná and its fructification effects. Three passion fruit plantations in Northern Paraná were evaluated in the counties of Londrina and Assaí. Transect census were realized in each area, delimiting two 50 meter-paths, where the presence of bee in the open flowers was registered. Transects were run through for five minutes, every 15 minutes, starting at 1 pm and finishing at 8 pm. Results showed that the bumblebees present in the Northern Paraná region were the Xylocopa frontalis and X. suspecta, with the predominance of the first. Highest fructification rates occurred in the areas with more frequency of bumblebees and low frequency of cleptobiotic bees. Lowest fructification rates were due to the absence of bumblebees or high frequency of cleptobiotic bees

ABSTRACT Nitrogen and potassium fertilization and assessment of adequate nutritional status are essential for increasing fruit production of passion fruit. However, studies related to characterization of the leaf nutrient concentration and content in passion fruit with different production capacities are scarce in the literature in Brazil. The objective of this study was to evaluate macronutrient leaf concentration and content in different parts of the reproductive shoot of yellow passion fruit subjected to different ratios of N and K fertilization. The study was conducted in a randomized block design, with three replications, following a 4 x 6 factorial arrangement consisting of four cultivars of yellow passion fruit (BRS Gigante Amarelo, IAC 275, BRS Ouro Vermelho, and BRS Sol do Cerrado) and six application rates of N-K2O fertilizer (0-0, 50-125, 100-250, 150-375, 200-500, and 250-625 kg ha-1 year-1). Two leaf sampling methods were adopted (leaf located at a position adjacent to the fruit, and leaf located at the end of the reproductive branch) for nutritional assessment. The leaf located at the adjacent position had lower N, P, K, Mg, and S concentration and higher Ca concentration than the concentrations observed in the standard leaf. However, the higher leaf dry matter in adjacent leaves resulted in increased macronutrient concentration/content. The increase in N-K fertilizations inhibited Ca and Mg content in the leaves adjacent to the fruit of the Gigante Amarelo, IAC, and Ouro Vermelho passion fruit cultivars, but did not affect Ca and Mg content in the standard leaf. The passion fruit cultivars showed different leaf nutrient contents after N-K fertilization, indicating variable nutritional demands and the need for specific diagnostic methods for each cultivar.

Abstract The use of advanced seedlings associated with the annual cultivation of passion fruit are important management techniques for living with the fruit-hardening virus (FEV). However, this technology still needs information on nitrogen fertilization and spacing between plants, so that it is possible to recover crop’s productivity. The objective of this research was to identify the nitrogen dose (N) and the most suitable spacing for annual orchards installed with advanced seedlings (1.2 m high) of yellow passion fruit. The experiment was carried out in the field, in Mogi Mirim, SP, between October 2017 and July 2018. A randomized block design was used in subdivided plots; the treatments were doses of N in coverage such as 0, 60, 120, 180 and 240 kg ha-1 and spacing between plants of 2.0 and 4.0 m and 3.0 m between lines. The dose found for maximum production, 15.4 kg of fruit pl-1, and adequate physical-chemical quality of the fruit for the yellow passion fruit was 130.7 kg ha-1 of N. The most densified spacing, of 2 x 3 m, provided greater productivity and number of thousand fruits per hectare, respectively, 20.7 t ha-1 and 139.5 thousand fruits ha-1.

ABSTRACT The objective of this study was to evaluate the effects of saline water irrigation management strategies and potassium doses on the concentration of photosynthetic pigments, gas exchange, and fruit production of ‘BRS GA1’ yellow passion fruit. The experiment was carried out under field conditions using a randomized block design, with treatments based on a 6 × 2 factorial scheme, related to six management strategies for irrigation with saline water (irrigation with low-salinity water throughout the crop cycle-WS; irrigation with high-salinity water in the vegetative stage-VE; flowering stage-FL; fruiting stage-FR; and successively in vegetative/flowering stages-VE/FL and vegetative/fruiting stages-VE/FR) and two doses of potassium (60 and 100% of the recommendation), with four replicates. The dose of 100% recommendation corresponded to 345 g of K2O plant-1 year-1. High electrical conductivity irrigation water (4.0 dS m-1) was used in different phenological stages according to treatment, alternating with water of low electrical conductivity (1.3 dS m-1). The synthesis of chlorophyll a and b, stomatal conductance, instantaneous carboxylation efficiency and water use efficiency of ‘BRS GA1’ yellow passion fruit were reduced under irrigation with water of 4.0 dS m-1 in all strategies adopted. Fertilization with 60% of the K recommendation promoted greater number of fruits and yellow passion fruit yield. Irrigation with 4.0 dS m-1 water in the vegetative/flowering and flowering stages reduced the yield of yellow passion fruit.

The initial protection of plants through the use of insecticides and fungicides has been shown to be efficient for a good management of pests and diseases, however the molecules used in seed treatment have demonstrated a physiological effect on germination and initial vegetative development. The present work had as objective the evaluation of the physiological effect caused by two insecticides and a fungicide on the germination and vigor of the seeds. A randomized block design with six treatments and four replications was used. The treatments were: T1-water; T2-Rocks® insecticide; T3-Insecticide Cruiser 350 FS®; T4-Maxim XL® fungicide; T5-Rocks® + Maxim XL® and T5-Cruiser 350 FS® + Maxim XL®. The application of the treatments was performed according to the manufacturers’ recommendations and the percentage of germination of the seeds was evaluated, on paper and sand roll substrates, the rate of emergence, the total length of seedlings, the electrical conductivity of the imbibition and aging solution accelerated, with a later pattern of germination. The data were submitted to Analysis of Variance and the means were compared by the Tukey test. The results indicated that there were statistically significant differences for all variables except paper germination. The treatments that received the application of the Maxim XL fungicide demonstrated superiority, both in the evaluation of germination in sand substrate, and in the vigor evaluations of seeds and seedlings, while the treatments that received application of Rocks insecticide were inferior to the other.

ABSTRACT Inhibiting seedling vegetative growth may be a strategy for improving modulation against biotic and abiotic stresses after transplanting. The objective of this study was to evaluate morphological responses of yellow passion fruit (Passiflora edulis) seedlings to growth inhibition resulted from the application of an inhibitor of gibberellin biosynthesis. The experiment was carried out in a greenhouse using seedlings grown in 290 cm3 polyethylene tubes. At 40 days after emergence, trays containing the seedlings were immersed in solutions at concentrations of 0, 40, 80, 120 and 160 mg (Paclobutrazol) PBZ L-1 up to substrate saturation. These five treatments were laid out in a randomized block design with four replicates. At 15, 30 and 45 days after PBZ application (DAA), basal stem diameter was measured; at 45 DAA, stem diameter, individual leaf area, specific leaf area, root diameter and root volume were measured, lignin content and the anatomy of leaves, stems, and roots were analyzed. Triazole-induced anatomical alterations in stems, leaves and roots cause morphological traits and intensify the specific reagent staining of phenolic compounds and lignin in yellow passion fruit (Passiflora edulis) seedlings.
