Postharvest changes and respiratory pattern of bacuri fruit (Platonia insignis Mart.) at different maturity stages during ambient storage Acta Amazonica
Teixeira,Gustavo Henrique de Almeida; Durigan,José Fernando; Lima,Maria Aparecida; Alves,Ricardo Elesbão; Filgueiras,Heloísa Almeida Cunha.
Bacuri (Platonia insignis, Mart.) is one of the most important among Amazonian fruits. However, little is known about its postharvest physiology, such as maturity stages, changes during ambient storage, and respiratory pattern. Fruits were harvested at three maturity stages based on epicarp colour: dark green, light green, and turning (50% yellow), in order to determine colour modification and respiratory pattern during ambient storage (25.2 ºC, 75.1 % RH). Fruit of all maturity stages showed, after three days of harvest, a non-climacteric respiratory pattern, with turning fruit presenting the highest CO2 production rate until the fourth storage day (177.63 mg.CO2.kg-1.h-1). Yellowing increased throughout storage as related to lightness, chromaticity, and...

Fruit ontogeny of Garcinia gardneriana (Planch. & Triana) Zappi (Clusiaceae) Acta Botanica
Asinelli,Marta Eglaé Camargo; Souza,Maria Conceição de; Mourão,Káthia Socorro Mathias.
Garcinia gardneriana (Clusiaceae) is a small to medium-sized tree that usually occurs on the floodplains of the Paraná River and it is an important food source for the local inhabitants. The fruit itself is consumed in natura, and juices and sweets are made from it. The purpose of this study was to describe morphological and structural aspects of fruits and seeds of this species in order to classify the fruit type and the pulpy layer which involves the seeds. The material analyzed consisted of ovary and fruits in different stages of development, collected from five plants from Aurélio Island, Baía River (MS, BR) and the description was done according to standard procedures in anatomy. The fruit is a yellowish-orange spherical berry ("bacóide" type). The...
