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.

O extrativismo de mangaba é “trabalho de mulher”?: duas situações empíricas no Nordeste e Norte do Brasil
(2008-12) MOTA, Dalva Maria da; SCHMITZ, Heribert; SILVA JÚNIOR, Josué Francisco da; RODRIGUES, Raquel Fernandes de Araújo; ALVES, Jackeline Nakata F.
Despite recent academic investments, the work of the women is not very well known yet, as the insistent initiatives of emphasizing its importance for their lives prove to be, so they become more visible and valued. This little knowledge agrees with the fact that the habitual categories of economical and social analysis, for a long time, either omitted or denied female activities, or associated them exclusively to a particular universe called “the works of the women”, marked by a large number stereotypes which escamoteiam socially acquired capacities. The aim of this article is to analyze the social construction of the notion of “work of women” from the refl ection of the two empirical situations of the Extractivism of mangaba practiced, predominantly, by the women of the North and Northeast of Brazil. The research was made in 2007, in the towns of Indiaroba/SE (Village of Pontal) and in Salvaterra/PA (Marajó Island). Besides the distance and the social-cultural particularities, there is still the idea that the extractivism of mangaba is “work of women”. What are the meanings attributed to this expression in so different contexts?

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.
