A mangabeira (Hancornia speciosa Gomes) destaca-se por possuir um grande potencial como planta frutífera e produtora de borracha. As dificuldades encontradas no seu processo de propagação por meio de sementes, devido, principalmente, à baixa taxa de germinação e à recalcitrância, valorizam a busca por soluções alternativas para a produção de mudas dessa espécie, de maneira rápida e eficiente. Objetivou-se, neste trabalho, realizar o estudo da germinação de sementes de mangabeira em condições in vitro, tendo como precedente a obtenção de explantes, para posterior utilização no cultivo in vitro. Neste estudo foram avaliados os efeitos de diferentes meios de cultura, concentrações de sacarose e GA3 e de três níveis de pH na germinação da mangabeira. Frutos maduros foram coletados, passaram por processo de beneficiamento e tiveram suas sementes retiradas e utilizadas como explantes. Maior porcentagem de germinação de sementes de mangabeira in vitro foi obtida com a utilização dos meios de cultura WPM e MS/2, suplementados com 15,0 g L-1 de sacarose, 0,2 mg L-1 de GA3 e com pH corrigido para 5,8.

Displays the Information Literacy as a method of training for access, evaluation and use of information, which has become, increasingly, the raw material indispensable for intellectual autonomy. Presents the articulation possible - and necessary - between Information and Cultural Competence in School, with emphasis on their relationship. Search is on School Culture, contexts for insertion of procedures developed by the Information Literacy, considering the dimensions of the organization, interpretation and knowledge production. It points out the advantages to realize the Culture School, through practical philosophical context, to support action planning, establishing, in the educational environment, actions related to the development of Competency Information. We used participation research action in the context of a public school in Campo Grande-MS, the research subjects were students of the 6º and 7º grades and their teachers. Data collection took place through observation and interviews relating the development of competencein Information and teaching practices It is noteworthy that this kind of responsibility if developed without an understanding of school culture, becomes a rambling and disjointed practice whose outcomes are at risk of not being achieved.

The low productivity of crambe can be associated with many factors, among these, the competition with weeds, which reduces the yield, harvest affects and contributes to the increase in seed moisture. Therefore, this study aimed to evaluate the tolerance of crambe plants cv. FMS Brilhante to herbicides applied in preplant incorporated (PPI), preemergence (PRE), and postemergence (POST). The study was installed in a green-house and the treatments consisted of the herbicide application in: pre-plant incorporated ofdiclosulam, flumetsulam, metribuzin, and trifluralin; preemergence applicationof atrazine, diclosulam, diuron, flumetsulam, metribuzim, S-metolachlor, sulfentrazone, and trifluralin; and postemergence application ofbentazon, carfentrazone-ethyl, clefoxydim, cletodim + fenoxaprop-p-ethyl, ethoxysulfuron, fomesafen, fluazifop-p-butyl, flumioxazin, halosulfuron, imazamox, imazapic, lactofen, nicosulfuron, oxadiazon, quinclorac, and setoxydim. Visual evaluations of phytotoxicity on crambe plants were realized after applications, the seedlings were counted and the height and plant dry matter were determined in the end of the evaluation period. In conditions where the studies were conducted, we can conclude that only the trifluralin application in PRE and the application of clefoxidim+fenoxaprop-p-ethyl, fluazifop-p-butyl, quinclorac, setoxydim and clefoxydim in POST showed selectivity and potential use for FMS Brilhante crambe cultivar.

We intend to expose this paper a brief review about the social factors that include the capitalist system. Having the city of Rafard as our focus of study, we are going to analyze how agribusiness and migration have great political significance in this small town, and still are determining factors for socio-cultural training of its citizens, as well the formation and economic development of their own city. We are going to observe how a town with only 8.599 inhabitants is subjected to the laws dictated by capital through the interference of a large sugarcane agro industrial production unit present in its territory
