Atores, canais de comercialização e consumo da mangaba no nordeste brasileiro
(2008-03) MOTA, Dalva Maria da; SCHMITZ, Heribert; SILVA JÚNIOR, Josué Francisco da
The aim of this article is to analyse the processes which begins from raw material extraction to the consumption of mangaba, emphazising different actors, their relationships, marketing channels, and consumption characteristics. The research was carried out in the Northeast of Brazil (Brazilian states of Bahia, Alagoas, Sergipe and Pernambuco) using quantitative and qualitative approaches. The main results indicated weak domestication of mangaba trees to attend to an increasing market demand, and threats to extractivism by external factors.

Efeito de meios de cultura, concentrações de GA3 e pH sobre a germinação in vitro de mangabeira (Hancornia speciosa Gomes)
(2009) SOARES, Fernanda Pereira; PAIVA, Renato; STEIN, Vanessa Cristina; NERY, Fernanda Carlota; HERRERA, Raírys Cravo; OLIVEIRA, Lenaldo Muniz de
The Hancornia speciosa Gomes species presents potential for fruit and rubber production. Propagation is difficult primarily due, to a reduced seed germination and occurrence of recalcitrant seeds that stimulate the search of rapid and efficient propagation alternatives. In this context, the aim of this work was to study in vitro seed germination conditions in order to produce explants to be used on in vitro culture. The effect of different culture media, sucrose and GA3 concentrations and three pH levels were evaluated. Seeds were extracted from mature fruits after being harvested and processed. Higher in vitro germination was obtained using WPM and MS/2 media supplemented with 15.0 g L-1, 0.2 mg L-1 GA3 and pH adjusted to 5.8.

Gestão coletiva de bens comuns no extrativismo da mangaba no nordeste do Brasil
(2009-12) SCHMITZ, Heribert; MOTA, Dalva Maria da; SILVA JÚNIOR, Josué Francisco da
This article analyses the collective management of common goods within the context of mangaba fruit collection; it focuses on the access to resources, the institutional arrangements and the social conflicts among the involved actors. The research was undertaken in northeastern Brazil and is based on observations, interviews and secondary data. The study demonstrates the existence of well preserved mangaba trees due to collective management.
