RESUMOSão muitos os fatores que influenciam a qualidade final do fruto do maracujazeiro. Dentre esses podem ser destacados a qualidade das mudas, o manejo e tratos culturais adequados. Sendo assim, o objetivo do trabalho foi avaliar qualidade de frutos de maracujazeiro-amarelo cultivados com mudas em diferentes idades. Para a formação das mudas foram utilizadas sementes do maracujazeiro-amarelo cv. Redondo Amarelo, substrato composto por terra+areia+esterco na proporção de 3:1:1 e sacos plásticos com capacidade para 8 kg. O delineamento experimental utilizado foi em blocos ao acaso (DBC), com cinco tratamentos, formado por mudas de diferentes idades (25, 50, 75, 100 e 125 dias, após emergência), com quatro repetições de 12 plantas. As variáveis analisadas foram: massa fresca do fruto (g) diâmetro longitudinal e transversal do fruto (mm), índice de formato do fruto, espessura da casca (mm), porcentagem de casca, suco e semente (%), sólidos solúveis totais, acidez total titulável e pH. A utilização de mudas com idades de 100 e 125 dias após emergência no cultivo do maracujazeiroamarelo apresentou resultados satisfatórios para todas as características avaliadas, deduzindo-se ser viável sua utilização. O cultivo do maracujazeiro-amarelo formado com mudas de menor idade, em relação às demais obtiveram uma baixa produtividade, frutos menores e com menor rendimento de suco. PALAVRAS-CHAVE:Passiflora edulis, manejo, cultivo alternativo. ABSTRACTThe factors influencing the final quality of the passion fruit are many, among them the quality of seedlings and the adequate management and farming practices stand out. So, the objective of this work was to evaluate the quality of yellow passion fruit cultivated with seedlings at different ages. For the establishment of the seedlings seeds of the yellow passion fruit cv were utilized. Redondo Amarelo, substrate composed of soil+sand+manure in the ratio of 3:1:1 and plastic bags for up to 8 kg of weight. The experimental design utilized was in randomized blocks (DBC) with five treatments made up of different ages (25, 50, 75, 100 and 125 days, after emergence) with four replications of twelve plants. The variables surveyed were: fresh mass of the fruit (g) longitudinal and transversal diameter of the fruit (mm), fruit shape index, skin thickness (mm), percentage of skin, juice and seed (%), total soluble solids, total titrable acidity and (pH). The use of seedlings aged 100 and 125 days after emergence in yellow passion fruit cultivation showed satisfactory results for all characteristics, deducing feasible to use. The cultivation of yellow passion fruit formed with younger seedlings, compared to other ages obtained a low productivity, lower fruit and less juice yield.

“…The application of potassium chloride with cattle manure contributed to the increase in solid soluble contents of noni fruits due to the induction of synthesis and translocation of carbohydrates and activation of enzymes. It also contributed to the formation of organic acids, which was also found for yellow passion and melon fruits (Brito et al, 2005;Jifon and Lester, 2009). Even considering the soluble solid contents in the fruits, the values were lower than all values obtained by Kumar e Ponnuswami (2013) in fruits of noni under different irrigation regimes and sources of organic manure, which ranged from 7.21 to 10.53°Brix.…”

“…In soil fertilization, the use of organic materials added to mineral fertilizers, which significantly influence the root system architecture and the nutritional stage is crucial to the success of fruit production (Brito et al, 2005), for the application of organic sources and mineral fertilization influence on fruit quality of passion fruit plants. However, has little information about the effect of the organic and mineral fertilization on the physical and physicochemical quality noni fruit.…”

Noni has been introduced in Brazil just over a decade ago. Therefore, the information regarding crop fertilization and its influence on fruit quality is rare in the literature. Among macronutrients, potassium is highly concentrated in noni plants, and fertilization with cattle manure contributes to plant nutrition and fruit quality. This study sought to evaluate the effect of potassium fertilizer and cattle manure on the physical and physicochemical attributes of noni fruits. The treatments were distributed in randomized blocks, with four replications and two plants per plot, arranged in a factorial design 5 × 2 related to 0, 13.2, 37.5, 61.5 and 69.6 g plant -1 potassium chloride doses in soils without and with 12 kg plant -1 of cattle manure, with a C/N = 18:1 ratio. Cattle manure increased the average fruit weight from 99.6 to 113.4 g, expressing an increase of 13.9% for plants without and with organic compounds. Potassium chloride provided an increase of 61% in fruit weight and 31.25% in titratable acidity in fruits of plants without and with the highest dose of potassium chloride. Potassium chloride and cattle manure increased fruit mass, fruit length, fruit diameter, pulp mass, vitamin C and glucose contents in noni fruits.

“…The obtained results in this study are similar to those observed by Cobra (2015), when working in the same study area, where the averages ranged from (6.7mm) to (12.2mm), and Figueiredo et al (2015) that obtained values between (7.48mm) to (9.53mm). Brito et al (2005) in studies using treatments with different sources, and doses of organic fertilizers in passion fruit registered differences in the peel thickness evidencing that this characteristic is directly linked to nutritional factors.…”

-This study aimed to provide information on the biology and floral resources, stigmatic receptivity and viability of pollen grains during rainy season and dry season, and to evaluate the efficiency of natural and artificial pollination on quality of fruits of eight passion fruit cultivars sourced in Tangará da Serra -MT. Five commercial cultivars and three populations of the genetic improvement program of the sour passion fruit from the Universidade do Estado de Mato Grosso were evaluated. The climatic conditions of the rainy season favored the greater development of the floral pieces. The sugar concentration in the nectar presented higher averages in the rainy season, in all cultivars, except for FB 200. The climatic conditions of the dry season favored the replacement of the nectar volume. All cultivars evaluated presented pollen viability and stigmatic receptivity higher than 79% and 90%, respectively. The characteristics of fruit mass and percentage of pulp were better in artificial pollination, and the fruits obtained from natural and artificial pollination in all cultivars evaluated presented physical and chemical characteristics that are within the quality standards desired in the commercialization. Index terms: Floral biology, climate, Passiflora edulis. Morfometria, recursos florais e eficiência da polinização natural e artificial na qualidade de fruto em cultivares de maracujazeiro-azedoResumo -Este estudo visou a fornecer informações a respeito da biologia e dos recursos florais, da receptividade estigmática e da viabilidade dos grãos de pólen nas épocas de chuva e seca, e a avaliar a eficiência da polinização natural e artificial sobre a qualidade de frutos de oito cultivares de maracujazeiro-azedo, cultivadas em Tangará da Serra -MT. Foram avaliadas cinco cultivares comerciais e três populações do programa de melhoramento genético do maracujazeiro-azedo da Universidade do Estado de Mato Grosso. As condições climáticas da estação chuvosa favoreceram o maior desenvolvimento das peças florais. A concentração de açúcar no néctar apresentou médias mais elevadas na estação chuvosa, em todas as cultivares, com exceção de FB 200. As condições climáticas do período de seca favoreceram a reposição do volume de néctar. Todas as cultivares avaliadas apresentaram viabilidade polínica e receptividade estigmática superior a 79% e 90%, respectivamente. As características de massa de fruto e da porcentagem de polpa apresentaram-se melhores na polinização artificial. Os frutos obtidos de polinização natural e artificial, em todas as cultivares avaliadas, apresentam características físicas e químicas que estão dentro dos padrões de qualidade desejada na comercialização. Termos para indexação: Biologia floral, clima, Passiflora edulis.
