RESUMO -Este estudo teve como objetivo comparar a transposição do banco de sementes do solo de dois estádios sucessionais (floresta secundária inicial -Fi e floresta madura -Fm) de Floresta Estacional Semidecidual para um trecho de pastagem abandonada de Melinis minutiflora P. Beauv., na Reserva Mata do Paraíso, em Viçosa, MG. Foram alocadas em cada trecho sucessional de floresta 10 parcelas, bem como retiradas do centro de cada parcela amostras de 1 m² e 5 cm de profundidade de solo superficial, sendo em seguida depositadas em clareiras abertas na pastagem abandonada. No período de maio de 2008 a fevereiro de 2009, foram registrados, nas clareiras cobertas com banco de sementes, 231 indivíduos, distribuídos em 13 famílias, 17 gêneros e 22 espécies. As espécies mais abundantes foram a Vernonia polyanthes, com 108 indivíduos; e Senna multijuga, com 39. As diferenças de riqueza e densidade entre os bancos de sementes oriundos dos dois trechos sucessionais foram significativas a 1% de probabilidade, sendo a maior densidade encontrada no banco de sementes do solo procedente do trecho Fi. As clareiras-testemunha foram colonizadas por herbáceas e, principalmente, pela gramínea exótica Melinis minutiflora. Este estudo mostra que é recomendável e viável a adoção da técnica de transposição do banco de sementes como metodologia de restauração florestal de pastagem abandonada, devendo o banco ser coletado, preferencialmente, em florestas secundárias em estádio sucessional inicial.Palavras-chave: Nucleação, Sucessão florestal e Recuperação de áreas degradadas.

“…The bracts and bracteoles are usually conspicuous and imbricate. The species of Justicia can be easily recognized by their bilabial corolla, with a posterior lip that is generally two-lobed, an anterior lip that is threelobed, two stamens, a capsule with four seeds, and a basal sterile portion (Graham, 1990;Braz et al, 2002). Table 1 shows the vegetal species of the genus Justicia with previous chemical and/or biological studies, indicating their botanical synonymy, popular name, and geographical distribution.…”

Abstract:The Acanthaceae family is an important source of therapeutic drugs, and the ethnopharmacological knowledge of this family requires urgent documentation as several of its species are near extinction. Justicia is the largest genus of Acanthaceae, with approximately 600 species. The present work provides a review addressing the chemistry and pharmacology of the genus Justicia. In addition, the biological activities of compounds isolated from the genus are also covered. The chemical and pharmacological information in the present work may inspire new biomedical applications for the species of Justicia, considering atom economy, the synthesis of environmentally benign products without producing toxic by-products, the use of renewable sources of raw materials, and the search for processes with maximal efficiency of energy.

The floristic variations of shrub and tree components were studied in two sites of Semideciduous Forest, initial forest and mature forest, located in the Mata do Paraíso Forest Reserve, in Viçosa, State of Minas Gerais, Southeastern Brazil, in order to analyze the floristic similarity and the correlations between environmental variables and the distribution of tree species in these forests. Individual trees with a diameter at breast height (DBH) ≥ 4.8 cm were sampled in twenty 10 x 30 m plots (10 plots in each site). The plots were distributed systematically at 10 m intervals. The environmental variables analyzed were: the canopy openness and soil chemical and texture characteristics. The two forest sites showed clear differences in the levels of canopy openness and soil fertility, factors that reflect the floristic and successional differences of the shrub and tree component, revealed by the low similarity between these forests by cluster analysis. The canonical correspondence analysis (CCA) of environmental variables and species abundance indicated that the species in these forests studied are distributed under strong influence of canopy openness, moisture and soil fertility.
