The production of passion fruit seedlings constitutes one of the important stages of the production system and the importance of substrate for the seedlings growth and plant performance in the field. Therefore, the objective of this study was to evaluate the effects of different composting organic wastes in the substrate composition for production of yellow passion fruit seedlings. The experiment had been conducted in the Centre of Human, Social and Agricultural Sciences at The Federal University of Paraíba. The experimental design was randomized block design, with six treatments, goat composite + soil (CCP+S), poultry composite + soil (AC+S), bovine composite + soil (CB+S), rabbit composite + soil (CCO+S), earthworm humus + soil (MH + S), and soil (S) and S in the ratio of 2:1 (v/v) and five repetitions. Emergency speed index, emergency percentage, stem diameter, seedling height, leaf number, root length, fresh root mass, shoots fresh mass, total of fresh mass, dry mass of root, dry mass of branches, total dry mass, chlorophyll a, b and total, and Dickson quality index were assessed. The compounds in the constitution of substrates exerted significant effect on the characteristics evaluated in the passion fruit, which may be related to the availability of nutrients to the substrate. The substrates containing CCP+S and CCO+S provided better growth, chlorophyll contents and quality of "Serra" yellow passion fruit seedlings.

“…The number of emerged seedlings was counted daily from the 7th to the 28th day after sowing (DAS) to verify stabilization of germination, according to the methodology contained in the Rules for Seed Testing for the passion fruit seeds (Brasil, 2009). Emerged seedlings were considered to be those that had cotyledons fully expanded above the surface of the substrate.…”

-Seedlings for commercial growing of passion fruit are preferentially acquired through seeds. Success in germination and seedling emergence, in turn, is influenced by the genetic constitution of the progenies and the thermal conditions imposed on the growth environment. The aim of this study was to evaluate the emergence and vigor of seedlings of passion fruit cultivars exposed to different temperatures. The experiment was conducted in a germination chamber at the Unidade de Ensino, Pesquisa e Extensão / Pomar Campus of the Department of Plant Science of the Universidade Federal de Viçosa (UFV). The study was carried out in 5 × 3 factorial arrangement, with five temperature ranges (5-15, 10-20, 15-25, 20-30 and 25-35 °C) and three varieties of passion fruit (BRS Sol do Cerrado, BRS Gigante Amarelo and FB-200 Yellow Master) in a completely randomized design with six replications of 25 seeds per plot. The variables analyzed were the percentage, the speed index, and the average time of emergence, shoot length, total length, and seedling dry matter. The cultivars BRS Sol do Cerrado and BRS Gigante Amarelo exhibited seedling emergence of over 95% in the temperature ranges of 20-30 °C and 25-35 °C. Alternating temperatures from 20-30 °C stimulates seedling emergence, seedling growth, and greater accumulation of seedling dry matter.Index terms: Passiflora edulis Sims, cultivars, seeds, thermal conditions. Emergência e vigor de plântulas de maracujazeiro azedo em função da temperatura RESUMO -A propagação de plantas de maracujazeiro azedo, em plantios comerciais, é realizada preferencialmente por meio de sementes. O sucesso da germinação e emergência de plântulas, por sua vez, é influenciado pela constituição genéticas das progênies e pelas condições térmicas impostas no ambiente. O objetivo neste trabalho foi avaliar a emergência e o vigor de plântulas de cultivares de maracujazeiro azedo sob exposição de diferentes temperaturas. O experimento foi conduzido em câmara de germinação na Unidade de Ensino, Pesquisa e Extensão/Pomar Campus pertencente ao Departamento de Fitotecnia da UFV. O trabalho foi desenvolvido em esquema fatorial 5 × 3, com cinco faixas de temperatura (5-15; 10-20; 15-25; 20-30 e 25-35 °C) e três cultivares de maracujazeiro azedo (BRS Sol do Cerrado, BRS Gigante Amarelo e FB-200 Yellow Master) no delineamento inteiramente casualizado e seis repetições de 25 sementes por parcela. As variáveis analisadas foram as percentagem, índice de velocidade e tempo médio de emergência, o comprimento da parte aérea e total e massa seca de plântula. As cultivares BRS Sol do Cerrado e BRS Gigante Amarelo apresentaram emergência de plântulas acima de 95% nas faixas de temperaturas de 20-30 °C e 25-35 °C. Temperaturas alternadas 20-30 °C estimulam a emergência, o crescimento e maior acúmulo de massa seca das plântulas.

ResumoMudas vigorosas e bem formadas são imprescindíveis para o sucesso da fruticultura. O maracujazeiro-azedo é uma das principais frutíferas tropicais cultivadas no Brasil e é propagado convencionalmente por sementes, porém nem sempre suas mudas atingem desenvolvimento ideal no momento da implantação da cultura. O uso de um produto alternativo como fonte de nutrientes minerais para potencializar o crescimento e o desenvolvimento das mudas favoreceria sua formação e, consequentemente, seu sistema de produção. Este trabalho teve como objetivo avaliar o crescimento e o desenvolvimento de mudas de maracujazeiro-azedo submetidas à aplicação de fonte de nutrientes minerais alternativa. Para isso, mudas de maracujazeiro-azedo foram formadas em tubetes e acondicionadas em estufa plástica entre os meses de julho e outubro de 2012. O complexo hidrossolúvel (CH) foi aplicado em cobertura mediante irrigação quinzenal com soluções em suas respectivas concentrações de 0; 500; 1.000 e 2.000 mg L -1 sobre as mudas, na presença ou na ausência de adubação química. Aos 80 dias após a semeadura, foram efetuadas as avaliações das características altura, diâmetro do colo, número de folhas, comprimento de raiz e massas das matérias fresca e seca da parte aérea e do sistema radicular. O CH favoreceu a qualidade das mudas de maracujazeiro-azedo, especialmente na promoção de melhores resultados em altura e massas das matérias fresca e seca da parte aérea, na concentração de 2.000 mg L -1 , porém a adubação química foi importante para sua formação.Palavras-chave adicionais: crescimento; fertilização; maracujá; Passiflora edulis; propagação. AbstractVigorous and well formatted seedlings are very important for success of the fruit crops. The yellow passion fruit is one of the most important tropical fruit tree cultivated in Brazil whose the propagation usually has occurred by seed, however its seedlings are not always developed sufficiently at the time of planting. Thus, the use of an alternative product as source of mineral nutrients to potentiate seedlings growth and development could be positive for its production system. The objective of this work was to evaluate the growth and development of yellow passion fruit seedlings on water-soluble complex application. For that, the yellow passion fruit seedlings are formatted in plastic tubes into the greenhouse covered with plastic during July to October, 2012. The watersoluble complex (WSC) was applied biweekly in side dressing by solutions on concentrations of 0, 500, 1000 e 2000 mg L -1 under the seedlings cultivated with or without chemistry fertilization. After 80 days, the characters were evaluated measuring seedling height, stem base diameter, number of leaves, longest root, fresh and dry matter of aerial parts, and fresh and dry matter of roots. The WSC promoted quality of the yellow passion fruit seedlings, especially increasing its height, fresh and dry matter of aerial parts by concentration of 2,000 mg L -1 , however chemistry fertilization was important for its formation.
