Productivity, Fruit Physicochemical Quality and Distinctiveness of Passion Fruit Populations

Abstract

-The productivity and physicochemical quality evaluation is important, as it identifies superior populations. however, launching products requires following the descriptors according to DhE test instructions. Thus, this study aimed to evaluate three passion fruit populations with high productivity and physicochemical quality characteristics for commercial launch. The experiment was conducted at the State University of Mato Grosso experimental area, located in the municipality of Tangará da Serra, MT. The experimental design was complete randomized block design with four replicates and ten plants per plot. The physicochemical characteristics were submitted to analysis of variance and compared by the Tukey test. For the distinctiveness test, 25 descriptors were evaluated, where quantitative data have been converted into multicategoric data to obtain the dissimilarity matrix. From the dissimilarity matrix, groups were formed using the Tocher and UPGMA methods, Livestock and Supply Department. The highest productivity and number of fruits were verified for BRS Rubi Cerrado cultivar and UNEMAT S10 population. Populations and cultivars presented physicochemical characteristics that meet the required quality for both fresh consumption and industry use. Based on the distinction test among genotype, it was observed that the descriptors were effective for population differentiation. UNEMAT S10 population has characteristics that distinguish it from other cultivars and populations evaluated, and presents high agronomic performance; therefore, it can be launched as a commercial cultivar. Index terms: Commercial launch, Descriptors, Passiflora edulis Sims. PRODUTIVIDADE, QUALIDADE FÍSICO-QUÍMICA DE FRUTOS E DISTINGUIBILIDADE DE POPULAÇÕES DE MARACUJAZEIRO-AZEDORESUMO -A avaliação da produtividade e da qualidade físico-química apresenta importância, pois permite identificar populações superiores. Porém, para lançar material, é necessário seguir os descritores conforme as instruções para a execução dos ensaios de DHE. Desta maneira, objetivou-se avaliar três populações de maracujazeiro-azedo que apresentem características de alta produtividade e qualidade físico-química, para lançamento comercial. O experimento foi conduzido na área experimental da Universidade do Estado de Mato Grosso, situada no município de Tangará da Serra-MT. O delineamento experimental foi o de blocos completos casualizados, com quatro repetições e dez plantas por parcela. As características físico-químicas foram submetidas à análise de variância e comparadas pelo teste de Tukey. Para avaliar a distinguibilidade, foram utilizados 25 descritores, onde os dados quantitativos foram convertidos em multicategóricos, visando a obter matriz de dissimilaridade. A partir da matriz de dissimilaridade, formaram-se grupos pelo método de Tocher e UPGMA. A maior produtividade e o maior número de frutos foram verificados na cultivar BRS Rubi do Cerrado e na população UNEMAT S10. As populações e as cultivares apresentaram características físico-químicas que ate...

Productive Potential of Yellow Passion Fruit Applying Mineral and Organic Fertilization with Worm Compost

“…In the second cycle, the mass of fruits increased exponentially until the estimated proportion of 35%, because, probably, below this proportion the supply of nutrients, especially N and K, with reported effects on the variable in question (AULAR et al, 2014), was short of the demand of plant of passion fruit to express the limit of mass gain of fruits, which may have occurred due to the supplementary nitrogen fertilization have been residual and not present effect. With the same cultivar, Aguiar et al (2017) obtained fruits with mass of 325.7 g and Cavalcante et al (2016) with a mass of 257 g, interval that includes the values obtained in this study of 320 g, for the first cycle, and 318.4 g, for the second cycle.…”

“…The mineral and organic fertilization does not ns=non-significant, * and ** significant at 5% and 1% respectively Source: survey data. Cavalcante et al (2016) using the same cultivar obtained values of 84.2 and 99.6 mm, respectively, for the diameter and length. Just as occurred with the mass of fruits, the absence of response of chemical fertilization in the first cycle, to the diameters of the fruits, suggests that the worm compost applied during the first year of cultivation presented additional effect.…”

Post-harvest conservation of Passiflora alata fruits under ambient and refrigerated condition

“…On the present study, the only significant variation occurred in the fruits packed in 30μm HDPE maintained under ambient conditions (Table 2). Typicaly, the higher the Ratio, the more palatable will be the juice or the fruit pulp, since the soluble solids content is high and the acidity is low (Cavalcante et al, 2016).…”

Use of phosphites in postharvest to control anthracnose of yellow passionfruit

“…The phosphites K1, K2, Ca1 and Zn were the ones which reduced more the disease lesion size (Table 1). Some works were performed with phosphites of K and Ca (BRACKMANN et al, 2004;BRACKMANN et al, 2005;ANDREU;CALDIZ, 2006;BLUM et al, 2007;DUTRA et al, 2018), and, considering the results presented (Table 1), two experiments were carried out with dose variation of phosphites K2 (40%P 2 O 5 +20%K 2 O, 1.5mL.L -1 ) and Ca1 (30%P 2 O 5 +7%Ca, 3mL.L -1 ). Provided the average of tests, the doses of Ca1 and K2 reduced significantly the diameter of the lesion (Table 2).…”
