LEMOS, Lorena Moreira Carvalho et al. Physical and chemical characteristics of 'pêra' orange from different positions of the canopy . Rev. Bras. Frutic. [online]. 2012, vol.34, n.4, pp.1091-1097. ISSN 0100-2945.  https://doi.org/10.1590/S0100-29452012000400016.

The aim of this work was to evaluate the physical and chemical characteristics of fruit harvested from different positions of the canopy of 'Pêra' orange tree. The canopy was divided into three heights (basal, intermediate and apical), two sides (opposite to the canopy, toward the inter rows - East and West) and two positions (periphery and 30 cm into the inner part of the canopy). Harvest was made on July 9th, 2009. Fruit in the periphery of the canopy presented greatest values of fresh mass, longitudinal diameter, transversal diameter and thickness of flavedo, content of soluble solids, maturation index and yellower coloration of the peel than the fruits in the inner part of the canopy. Concerning concentrations of C vitamin and titratable acidity, fruits collected from the periphery of the canopy were the ones with the lowest concentrations. For height of the canopy, fruit collected from the apical part of the canopy presented greatest fresh mass and longitudinal diameter than fruit collected form the basal part. It was verified greatest contents of soluble solids and maturation in the fruit turned to the West face.
