| Abstract Conservation management systems that have intended to prevent wear or soil degradation have been widespread in agriculture. The study was conducted in Site São Luiz at Simonsen district, Votuporanga, São Paulo State, in order to evaluate the chemical and physical changes in an area with agrosilvopastoral system and deployed with three soil management (treatments): Full (conventional tillage, liming and application of gypsum, phosphate and potassium); intermediate (no tillage, liming and application of gypsum at surface) and basic (no tillage and surface liming). The soil was managed in July 2009 and the planting of eucalyptus was realized in January 2010, on the terraces. Between the terraces it was cropped maize intercropped with Urochloa... |

| O presente trabalho teve como objetivo avaliar a fungitoxicidade dos extratos brutos aquosos (EBA) de gengibre (Zingiber officinalis) e eucalipto (Corymbia citriodora) sobre o fungo Helminthosporium sp. Este patógeno foi identificado nas fibras do pseudocaule da bananeira, as quais são utilizadas na fabricação de artesanato local. Foram avaliados o crescimento micelial e esporulação do fungo in vitro, além do crescimento da colônia fúngica nas fibras tratadas com os extratos das plantas. As fibras receberam os seguintes tratamentos: preventivo (P), curativo (C) e T0, sendo que neste último, a inoculação e o tratamento com os EBAs foram realizados simultaneamente. Os resultados in vitro mostraram que, dos extratos testados, eucalipto foi mais eficiente na... |

| Gas exchange, chlorophyll afluorescence, and photosynthetic pigments of Xylopia sericeaA. St.-Hil. and Siparuna guianensis Aubl. were evaluated during the rainy season and the dry season (2009-2010) in three understories with different ecological conditions (irradiance, water availability, and temperature) located in the União Biological Reserve (known as REBIO União), at Rio de Janeiro State, a natural forest understory, eucalyptus understory under regeneration, and understory of eucalyptus plantation with 18-year-old trees that were removed 1 year before. The lowest values of Fv/Fm e Fm/Fo were observed in the exposed understory for both seasons, with lower values in the dry season, suggesting that reduced water availability potentializes the... |
