The partitioning of rain water into throughfall, stem¯ow and interception loss when passing through plant canopies depends on properties of the respective plant species, such as leaf area and branch angles. In heterogeneous vegetation, such as tropical forest or polycultural systems, the presence of dierent plant species may consequently result in a mosaic of situations with respect to quantity and quality of water inputs into the soil. As these processes in¯uence not only the water availability for the plants, but also water in®ltration and nutrient leaching, the understanding of plant eects on the repartitioning of rain water may help in the optimization of land use systems and management practices. We measured throughfall and stem¯ow in a perennial polyculture (multi-strata agroforestry), monocultures of peach palm (Bactris gasipaes) for fruit and for palmito, a monoculture of cupuacË u (Theobroma grandi¯orum), spontaneous fallow and primary forest during one year in central Amazonia, Brazil. The eect on rain water partitioning was measured separately for four useful tree species in the polyculture and for two tree species in the primary forest. Throughfall at two stem distances, and stem¯ow, diered signi®cantly between tree species, resulting in pronounced spatial patterns of water input into the soil in the polyculture system. For two tree species, peach palm for fruit (Bactris gasipaes) and Brazil nut trees (Bertholletia excelsa), the water input into the soil near the stem was signi®cantly higher than the open-area rainfall. This could lead to increased nutrient leaching when fertilizer is applied close to the stem of these trees. In the primary forest, such spatial patterns could also be detected, with signi®cantly higher water input near a palm (Oenocarpus bacaba) than near a dicotyledonous tree species (Eschweilera sp.). Interception losses were 6 . 4% in the polyculture, 13 . 9 and 12 . 3% in the peach palm monocultures for fruit and for palmito, respectively, 0 . 5% in the cupuacË u monoculture and 3 . 1% in the fallow. With more than 20% of the open-area rainfall, the highest stem¯ow contributions to the water input into the soil were measured in the palm monocultures and in the fallow.

DETERIORATION OF Eucalyptus spp. WOOD BY XYLOPHAGOUS FUNGIABSTRACT: This research aimed to test the deteriorating ability of fungi isolated from Eucalyptus spp. wood and perform chemical analysis of wood deteriorated, to verify which components of wood suffered major changes in the light of the attack. The experiment was conducted in the Laboratório de Biodeterioração da Madeira, Departamento de Ciências Florestais e da Madeira, Centro de Ciências Agrárias, Universidade Federal do Espírito Santo in the municipality of Jerônimo Monteiro, ES, Brazil. A total of 12 fungi were used, and nine of these came from pure cultures isolated from fragments of stumps of eucalypt woods deteriorated, collected in three distinct locations, and three with recognized capacity of deterioration that were used as the standard of comparison. The Basidiomycetous fungi 1 and 2 showed high capacity of deterioration of Eucalyptus spp. The heartwood of eucalypt showed a greater natural resistance than the sapwood, but the fungi were able to degrade both them. In general, there were, an increase in the content of extractives in wood damaged (heartwood and sapwood), for Basidiomycetous 1 and Basidiomycetous 2. The heartwood of Eucalyptus grandis there was a decrease in extractives content for both Basidiomycetes. To the holocelulose (cellulose and hemicelluloses), there were small differences between the healthy and damaged wood (mean variations around 1 %). The Fungi, Basidiomycetous 2 caused a greater degradation of lignin as compared to the Basidiomycetous 1.

RESUMOEste trabalho objetivou caracterizar tecnologicamente a madeira de teca (Tectona grandis) obtida de desbastes e avaliar sua potencialidade para a confecção de móveis. Foram empregadas madeiras provenientes de três árvores com idade de seis a sete anos, de um plantio no município de Guarapari, ES. A madeira analisada apresentou densidade básica de 0,45 g cm -³ e contrações de 2,72, 6,17 e 9,84 % (radial, tangencial e volumétrica), com coeficiente de anisotropia de 2,22. Com base nesses resultados e dos ensaios de flexão estática e compressão paralela às fibras a madeira testada pode ser utilizada na confecção de móveis de pequenas dimensões. Para a resistência a cupins de madeira seca (Cryptotermes brevis), foram ensaiadas amostras de cerne e alburno, sendo o cerne mais resistente que o alburno. De modo geral, a madeira foi classificada como de resistência moderada ao ataque de cupins de madeira seca. A madeira de teca jovem apresentou fácil usinagem, trabalhabilidade e acabamento. O móvel (mesa) confeccionado atendeu às características estéticas e de acabamento desejadas, agregando valor ao produto oriundo de primeiro desbaste, considerado, atualmente, um resíduo e empregado para finalidades com menor valor agregado.

The woods were from of three trees with approximate age of seven years removed from a plant in the municipality of Guarapari, ES, Brazil. The wood analyzed showed basic density of 0.45 g cm -³ and shrinkings of 2.72, 6.17 and 9.84% (radial, tangential and volumetric) with anisotropy coefficient of 2.22. On the basis of these results and ones of the assays of static bending and compression parallel to grain the tested wood can be used in the manufacture of small furniture. For resistance to wood dry termite (Cryptotermes brevis), were tested samples and heart and sapwood, with heartwood stronger than the sapwood. Generally speaking, wood was ranked as moderate resistance to wood dry termite attack. The teak wood young showed easy workability, machining and finishing. The furniture (table) manufactured attend the aesthetic characteristics and desired finish, adding value to the product from the first thinning, considered a residue and employed for purposes with less added value.
