The decoction of the stem barks from Bowdichia virgilioides KUNTH is a folk remedy used to treat inflammatory disorders in Latin American and Brazil. In the present study, the wound healing activity of aqueous extract of the stem bark from B. virgilioides, called AEBv, was evaluated by the rate of healing by wound contraction and period of epithelization at different days post-wound using the wound excisional model. On day 9, the AEBv-treated animals exhibited significative reduction in the wound area when compared with controls. In wound infected with S. aureus, the AEBv significantly improved the wound contraction when compared to the saline-treated mice. The histological analysis showed that AEBv induced a collagen deposition, increase in the fibroblast count and few inflammatory cells than compared to saline-treated group. The expression of collagen type I was increased in the group treated with AEBv as indicated by immunohistochemical staining. In vitro, the AEBv was effective only against S. aureus but not against P. aeruginosa. Together, the results of this study demonstrate, for the first time, the healing and antimicrobiological effects of aqueous extract of the stem bark from B. virgilioides in the therapy of skin wounds.

Weed Incidence After Soybean Harvest in No-Till and Conventional Tillage Croprotation Systems in Roraima’s Cerrado

et al. 2017

The goal of this study was to evaluate the occurrence of weeds after soybean harvest in rotational systems of no-till and conventional tillage in the savannah of Roraima, Brazil. Two simultaneous experiments were conducted in adjacent areas, the first one with no-till soil management system and the second one with the conventional system, with crop rotations for five agricultural years: pearlmillet (2007/2008), soybean (2008/2009), maize (2009/2010), cowpea with maize (2010/2011), soybean (2011/2012) and maize (2012/2013). The used experimental design was the randomized block one with 28 plots, sized 3 x 15 m (45 m2) distributed in 4 blocks. In May 2010, the combined sowing of cowpea and maize was performed, and later, during the same month of 2011 soybean was sown. Thirty days after harvesting, weeds were collected. The botanical classification of species was performed by classes, families, scientific and popular names, as well as comparisons with specialized bibliographies. The evaluated phyto-sociological parameters were: relative frequency (FRR), relative density (DRR), dominance (Do), importance value index (IVI), Sorensen’s similarity index (SI), numbers of individuals (ha-1) and dry mass (%). Among the 37 species found in both planting systems, 60% belonged to the Liliopsida class; Fabaceae and Malvaceae stood out. However, Poaceae, belonging to the Magnoliopsida class, had the highest number of species in both systems. Most weed species were common in both systems.

ResumoStylosanthes faz parte do clado Pterocarpus, tribo Dalbergiae. Possui 50 espécies distribuídas mundialmente e é principalmente diverso em áreas savânicas do Brasil. Este trabalho apresenta o estudo taxonômico do gênero Stylosanthes para o Estado de Roraima. Foram analisados materiais provenientes de trabalho de campo e de materiais depositados em herbário. Sete espécies foram encontradas em todas as fitofisionomias de savanas do estado: S. capitata, S. angustifolia, S. gracilis, S. viscosa, S. humilis, S. guianensis e S. scabra. São apresentadas chave de identificação, descrições e ilustrações, bem como informações sobre distribuição geográfica, ambientes preferenciais e usos econômicos das espécies. Palavras-chave: Amazônia, flora, Papilionoideae, Dalbergiae, taxonomia. AbstractStylosanthes is a member of the Pterocarpus clade, tribe Dalbergiae. It has 50 species with pantropical distribution and is greatly diversified in Brazilian savannas. Here we present a taxonomic study of Stylosanthes in Roraima state. Field work and herbarium surveys were extensive. Seven species were widely distributed over all savanna physiognomies: S. capitata, S. angustifolia, S. gracilis, S. viscosa, S. humilis, S. guianensis and S. scabra. An identification key, descriptions, illustrations, information on geographic distribution, habitat and uses for the species are also provided.
