<b>Aspects of the sensorial quality and nutraceuticals of <i>Plinia cauliflora</i> fruits

Abstract

ABSTRACT. Nationally known in Brazil, the jabuticabeira or jabuticaba tree produces fruits of wide commercial acceptance. However, little use of jabuticaba in commercial orchards and large genetic erosion of jabuticaba caused by human activities in its habitats have been historically observed. Thus, the goal of this study was to characterize fruits of the jabuticaba tree (Plinia cauliflora) in a forest fragment maintained in southwestern Paraná State in an attempt to identify trees with superior fruits for future selection as cultivars or male genitors. To this end, 15 variables linked to sensory and biochemical characteristics of harvested fruits were analysed during two years of production. Twenty percent of the genotypes that showed the highest frequency of superiority in the evaluated characteristics were preselected for analysis. The quality of the analysed fruits indicated their potential for use. Thus, this work resulted in the preselection of jabuticaba genotypes 7, 42, 43, 47, 54, 91, 97, 104, 105, 118, 134, 153, 154, 157, 163, 169, 177, 186, 212, J7-01, and J7-02, with 16 and 194 the only genotypes that had already been selected for superior characteristics during both growing cycles.Keywords: Myrtaceae, phenotypic variability, biochemical characteristics. Aspectos de qualidade sensorial e nutracêutica de frutos de Plinia caulifloraRESUMO. Nacionalmente conhecida, a jabuticabeira possui frutos de ampla aceitação comercial. Todavia, o que se viu historicamente foi a pouca utilização da mesma em pomares comerciais e a ampla erosão genética ocorrida pela ação antrópica em seus habitats. Dessa forma, o objetivo deste trabalho foi caracterizar frutos de jabuticabeiras (P. cauliflora) de fragmento florestal mantido no sudoeste do Estado do Paraná, buscando-se identificar aquelas denominadas superiores para seleção como futuro cultivar ou genitor masculino. Para tal, foram analisadas 15 variáveis ligadas as características sensoriais e bioquímicas que os frutos colhidos apresentaram durante dois anos de produção. Como critério de pré-seleção foi adotada a escolha de 20% dos genótipos que apresentaram a maior frequência de superioridade nas características avaliadas. A qualidade das frutas analisadas demonstrou potencialidade para uso. Dessa forma, o presente trabalho permitiu pré-selecionar as jabuticabeiras 7, 42, 43, 47, 54, 91, 97, 104, 105, 118, 134, 153, 154, 157, 163, 169, 177, 186, 212, J7-01 e J7-02, sendo a 16 e 194 as únicas que já podem ser selecionadas pelas características de superioridade entre ambos ciclos.Palavras-chave: Myrtaceae, variabilidade fenotípica, características bioquímicas.

Plinia peruviana “Yvapurũ” Fruits and Marmalade from Paraguay: Autochthon Products with Antioxidant Potential

“…It was reported that this fruit has up to 58.1 mg/100 g of anthocyanins in fresh whole fruit [6] and 298.8-426.3 mg/100 g in peel, which agrees with the values observed in the present work. In the pulp, they reported lower values, 0.071-2.024 mg/100 g [8], than what was observed in pulps and seeds, which are used for the preparation of handmade marmalade in Paraguay. The values obtained in the pulp and seed were higher than those reported by other authors for Plinia cauliflora pulp in Brazil (32.4 mg GAE/100 g), and lower than the values reported in fruit peel harvested in Minas Gerais, Brazil [8].…”

“…This result showed that the analyzed fruits harvested in Paraguay are smaller than those of synonymous species fruits in the state of Paraná, Brazil. These fruits weigh between 6.4 and 11.4 g and their diameter is near to 2.65 cm [7,8]. The pH values in the fruits are acidic and differ from the results reported by other authors (pH = 3.6-4.3) for the synonymous species of Plinia peruviana harvested in Brazil [7] P. cauliflora and P. trunciflora.…”

Growth and macronutrient absorption in ‘Sabará’ jabuticaba genotypes cultivated in nutrient solution

“…Jabuticaba (Myrciaria jabuticaba (Vell) Berg) is a fruit species native to Brazil, belonging to the Myrtaceae family. The lack of knowledge about production results in the low use of jabuticaba, which contributes to its genetic erosion (WAGNER JÚNIOR et al, 2017). However, it is a fruit that has high potential for food use.…”

Florescimento e frutificação da jabuticabeira \'Sabará\'

“…Entretanto, há pesquisas que verificaram valores variando de 6 a 8 gramas para massa dos frutos de jabuticabeira (Wagner Junior et al, 2017;. O período de deficiência hídrica na época do crescimento dos frutos nas condições do presente estudo, pode ter favorecido a menor massa média dos mesmos (Chitarra e Chitarra, 2005).…”

“…O período da antese a colheita dos frutos pode variar de acordo com as condições climáticas, cultivares e época do ano (Cavichioli et al, 2006). Segundo Araújos et al Araújos et al, 2010;Wagner Junior et al, 2017) para jabuticabeiras.…”
