Resumen

LIMA TEIXEIRA, Paulo de Tarso; GIACOMELLI, Sandro Rogério  y  PITON, Ricardo. Morphologic and physicochemical characterization of the fruits of mandarin 'Okitsu', 'Marisol' and tangor 'Ortanique'. Investig. Agrar. [online]. 2017, vol.19, n.1, pp.1-8. ISSN 2305-0683.  https://doi.org/10.18004/investig.agrar.2017.junio.1-8.

This work aimed to evaluate the morphological, physical and chemical quality of fruits of the mandarin Satsuma 'Okitsu', which belongs to the Group of Satsumas (Citrus unshiu Marcovitch), the mandarin 'Marisol', which belongs to the Group of Clementines (Citrus clementina Hort. ex Tanaka) and the tangor 'Ortanique' [C. sinensis (L.) Osbeck x C. reticulata Blanco]. The study was carried out at the Citrus Collection of the Polo of Technological Modernization from the Medio Alto Uruguay, located in Frederico Westphalen, State of Rio Grande do Sul, Southern Brazil. Analyses were performed to assess the size, density, percentage of juice of the fruits, maturation rates in the fruit juice (pH, total soluble solids, titulabre total acidity and relation between total soluble solids/ titulabre total acidity or ratio), and the ascorbic acid content (Vitamin C). Data were compared by Tukey test at p<0.05. The tangor 'Ortanique' showed total soluble solids, titulabre total acidity and ratio significantly higher than the mandarines. The mandarin 'Marisol' showed higher ascorbic acid content. The results were promising, because the mandarin 'Okitsu' and 'Marisol' and the tangor 'Ortanique' yielded in 2013 and 2014 showed that the fruit flavor characteristics were within the range founded to other hybrid and mandarins produced in other regions of Brazil. In this way they will be offered as alternatives to citrus growers in this region, further extending the harvest period of mandarins and seedless hybrids.
