Fruit quality of jabuticaba progenies cultivated in a tropical climate of altitude

Abstract

Fruit quality of jabuticaba progenies cultivated in a tropical climate of altitude. Abstract-Introduction. The jabuticaba tree (Myrciaria jabuticaba) belongs to the Myrtaceae family and produces a small fruit, native to central, southern and southeastern Brazil. Materials and methods. Fruits of 25 progenies of the jabuticaba tree, grown in a tropical highland climate, were evaluated as to physical, physicochemical and chemical characteristics: weight, longitudinal and transverse diameters, pulp and peel yields, seed mass, number of seeds per fruit, pulp and peel moisture, soluble solids, titratable acidity, [soluble solids/titratable acidity] ratio, pH, flavonoids, and phenolic compounds. The experimental design was completely randomized, the treatments being the 25 jabuticaba tree progenies. Results. A significant effect among progenies was observed for all characteristics evaluated. The chemical composition showed that the jabuticaba peel has a high phenolic compound content, and considerable flavonoid content. These results indicate that there is variability for the characteristics analyzed, enabling the economic exploitation of jabuticaba tree fruits for in natura consumption and processing. Conclusions. The physical and chemical characteristics combined can be proposed as excellent tools to select superior progenies. The fruits of five progenies showed desirable characteristics for the in natura market, while fruits of five other progenies hold high concentrations of natural antioxidants and may be listed as excellent options for the food industry.

Résumé-Introduction. Le jabuticaba (Myrciaria jabuticaba) appartient à la famille des myrtacées ; il produit de petits fruits et est indigène aux régions centre, sud et sud-est du Brésil. Matériel et méthodes. Des fruits de 25 descendances de jabuticaba, développées en climat tropical montagneux, ont été évalués quant à leurs caractéristiques physiques, physicochimiques et chimiques : poids, diamètres longitudinal et transversal du fruit, rendements en peau et pulpe, masse de graines, nombre de graines par fruit, taux d'humidité de la pulpe et de la peau, teneurs en solides solubles, acidité titrable, taux [solides solubles/acidité titrable], pH, teneurs en flavonoïdes et composés phénoliques. Le dispositif expérimental a été complètement randomisé, les traitements étant constitués par les 25 descendances de jabuticaba étudiées. Résultats. Un effet significatif de toutes les caractéristiques évaluées a été observé parmi les descendances. La composition chimique a révélé que la peau du fruit de jabuticaba a une teneur élevée en composés phénoliques, et un taux en flavonoïdes considérable. Nos résultats indiquent qu'il existe une variabilité parmi les caractéristiques analysées, justifiant une exploitation économique des fruits du jabuticaba pour sa consommation e...

Characterization and Correlation Analysis of Physical and Physico-Chemical Properties of Cambucá Fruits (Plinia edulis)

“…These values suggests that cambucazeiro fruits are fleshy, which is very interesting both for the industry and in natura consumption. Similar values to our results are observed in other Myrtaceae species, as in cagaita fruits, with pulp yield of 86.43% [10] and, in jabuticabeira fruits with 62.54% of the total fruits' mass corresponding to the pulp [3].…”

“…Averages for the physical and physico-chemical characteristics of Mytaceae species Plinia cauliflora (Jabuticaba), Camponesia phaea (Cambuci), Eugenia dysentery Dc. (Cagaita), Psidium friedrichsthalianum and Eugenia uniflora described in the literature [3,8,10,17,24] and the values verified in the present study are summarized in Table 4. There is quite diversity of sizes, forms, colors, organic acids and antioxidant compounds in species of Myrtaceae.…”

Estimation of the genetic diversity of jabuticaba trees and association among fruit characters

“…Therefore, high variation for fruit mass was observed. The values found were higher than those reported by Guedes et al (2014) in the region of Diamantina, MG for the "Sabará" variety. However, values were lower to those found by Zerbielli et al (2016) at a naturally occurring site in the region of Passo Fundo, RS, Brazil.…”

Complete sequence and comparative analysis of the chloroplast genome of Plinia trunciflora

“…Despite the nutritional and productive recognized importance of this species, the taxonomic classification is still controversial. This is mostly so because it is based on morphological evaluation of the trees, fruits and seeds, regarding physical, chemical, physicochemical, and germinal characters that have shown the existence of variability ( Guedes et al , 2014 ). Therefore, molecular studies are needed to better clarify the phylogenetic relationships among the species from this genus.…”
