Postharvest quality of ‘Roxo de Valinhos’ fig fruits grown in semi-arid conditions

Abstract

Aiming to evaluate the postharvest quality of ‘Roxo de Valinhos’ fig fruits grown in semi-arid conditions, this experiment was carried out in November, 2014, where fig fruit variety ‘Roxo de Valinhos’ were harvested from plants located at the didactic orchard of the Federal Rural University of Semi-Arid (UFERSA), Mossoró-RN, Brazil. Fruits were randomly harvested from 30 fig plants, spaced 2 m x 1.5 m, with 2 years old, according to three the fruit development stages (50%, 75% and 100% mature). The fruits were analyzed in Postharvest Physiology Laboratory, where the physical and chemical characteristics were evaluated, using 10 fruits for each stage. The evaluated characteristics were: weight, length, diameter, firmness, soluble solids, pH, titratable acidity and vitamin C. For the physical characteristics, fruits 100% mature presented the best results for weight, length and diameter, except for firmness which in fruits 50% mature presented the best results. For the chemical characteristics, only the soluble solid variable was signiicant and fruits 100% mature showed the best result, in this way, the fig tree ‘Roxo de Valinhos’ achieved the postharvest fruit quality and is viable for the semiarid region of the Rio Grande Norte State.

Post-harvest quality of fig fruit cultivated under in intensive pruning system in the Gurgueia valley

“…The pH remained within 5.19 and 5.45 for the fruits of the first cycle, and within 5.32 and 5.42 for those of the second cycle, with a significant difference occurring between stages and pruning times only for the green figs (Table 3). These values were above those of the studies by Freitas et al (2015) and Silva et al (2017a). The pH is an important attribute for the industrialization of the pulp since the lower is its value, the higher the antimicrobial effect and the guarantee of conservation (Caetano et al, 2017).…”

“…Additionally, few studies have been carried out with exotic species in semiarid regions. Silva et al (2017) found that figs from the 'Roxo de Valinhos' cultivar showed high quality under semiarid conditions.…”
