| In the upper Jequitinhonha valley, state of Minas Gerais, Brazi, there are large plane areas known as "chapadas", which are separated by areas dissected by tributaries of the Jequitinhonha and Araçuaí rivers. These dissected areas have a surface drainage system with tree, shrub, and grass vegetation, more commonly known as "veredas", i.e., palm swamps. The main purpose of this study was to characterize soil physical, chemical and morphological properties of a representative toposequence in the watershed of the Vereda Lagoa do Leandro, a swamp near Minas Novas, MG, on "chapadas", the highlands of the Alto Jequitinhonha region Different soil types are observed in the landscape: at the top - Typic Haplustox (LVA), in the middle slope - Xanthic Haplustox (LA),... |

| Palm swanp formations, the so-called veredas, typically occur in the Brazilian biome known as "Cerrado" (savanna-like vegetation), especially on flattened areas or tablelands (chapadas). The aim of this study was to characterize the mineralogy and micromorphology of soil materials from a representative toposequence of the watershed of the vereda Lagoa do Leandro, located in Minas Novas, state of Minas Gerais, Brazil, on plains in the region of the upper Jequitinhonha valley, emphasizing essential aspects of their genesis and landscape evolution. The toposequence is underlain by rocks of the Macaúbas group and covered with detrital and metamorphic rocks (schists of Proterozoic diamictites). The soil profiles were first pedologically described; samples of... |

| Neste trabalho, objetivou-se avaliar a época de maturação, dispersão, colheita e a qualidade fisiológica de sementes de sempreviva (Syngonanthus elegans (Bong.) Ruhland), em Diamantina, MG. Capítulos de S. elegans foram colhidos em cinco épocas (20/06/ 05, 20/07/05, 20/08/05, 20/09/05 e 20/10/05) em três locais de produção natural, dentro do Campus da UFVJM em um Neossolo Quartzarênico Órtico Típico (locais 1 e 2) e Neossolo Quartzarênico Hidromórfico Típico (local 3) e, posteriormente, submetidos a testes para avaliação do vigor e germinação das sementes. A qualidade fisiológica de sementes de S. elegans variou em função da época e local de colheita. Estratégias de manejo devem ser realizadas como a colheita após o início do período de dispersão das... |
