A quantificacao da biomassa e o conteudo de macronutrientes e Al foram estudados em Ceiba pentandra. Para tanto, foram selecionadas oito arvores da especie. Qautro delas foram amostradas aos 43 e quatro aos 55 meses de idade, apos o plantio. As mesmas foram separadas nos seguintes compartimentos: tronco; casca; folhas; peciolo e galhos. A biomassa seca total produzida por Ceiba foi de 82,03 t.ha aos 43 meses e 166,65 t.ha aos 55 meses. Nas mencionadas idades, essa biomassa distribuiu-se entre os compartimentos estudados na seguinte ordem decrescente (t.ha): tronco (45,31; 98,52); casca (15.19; 30,52); galhos (14,61; 28,71); folhas + peciolo (6,92; 8,90). Nas diferentes partes da especie estudada, os maiores acumulos registrados foram para: K no tronco; Ca... |

PREISINGER, H.; DUNISCH, O.; MORAIS, R. R. de; RICHTER, K.; ARAUJO, R. C.. |
Plants of six species from the Melastomataceae family (Miconia spp. and Bellucia spp.) taken from secondary forest stands of Terra Firme near Manaus, Amazonas, Brazil, were studied with regard to growth form, biometric traits of the plants, morphological and anatomical characteristics of leaves and wood. In addition, plant biomass and the content of mineral nutrients of different parts of the plants were analysed, and xylem flux measurements were carried out to determine the specific water uptake of the plants. The aim of the studies was to detect causal links between the parameters measured and the ecological behaviour of the species as observed in the field, in order to provide an autecological description of the species. The results show that the plant... |

Study on the important species (mogno, andiroba, cedro) for high quality wood production. During six years of experiments the influence of light, of the mineral element supply of the soil, and of the water supply on the growth dynamics of the trees was studied in a monoculture and an enrichment plantation installed at the Research Station of the Embrapa Amazonia Ocidental (Manaus-AM-Brasil). It was that the site preparation and the plantation management had a significant influence on the light conditions, the nutrient supply, and the water supply of the plantation. In comparison in the enrichment plantation the photoactive radiation (PAR) was strongly reduced, whereas the nutrient supply of the soil was better balanced and the seasonal oscillation of the... |

In this study the heartwood formation and the durability of seven years old plantation grown mogno, andiroba, cedro, cumaru, and jatoba was comparaed with wood from primary growth, in Manaus-AM (Brasil). The results are discussed with special regard to wood quality of plantation grown trees compared to primary growth. |

The aim of this study was to optimise the wood production of the Swietenia macrophylla King, Carapa guianensis Aubl., and Cedrela odorata L. (Meliaceaea) under plantation conditions with special regard to sustainable timber production in mixed plantations. According the results, the growth dynamics of the three Meliaceaea species was strongly correlated with the light, water, and nutrient supply, which offers the chance to select suitable sites and management practices by means of geographical information systems as to improve the timber production of these species in plantations like agroforestry systems, in Manaus-AM (Brazil). |

Investigações sobre espécies adequadas para o reflorestamento de áreas degradadas na Amazônia Central: In this SHIFT-PROJECT, eight native tree species of Central Amazonia (Swietenia macrophylla Krug., Carapa guianensis Aubl., Hevea brasiliensis (Willd.) Muell. Arg., Schizolobium amazonicum Ducke, Cedrela odorata L., Dipterix odorata Wylld., Hymenaea courbaril L., Tabebuia sp.), wich are accepted for timber production, are investigated with regard to their suitability for agroforestry systems. Therefore exogenous influences on tree growth and wood formation of these species are investigated on three-year-old experimental plots laid out by the EMBRAPA-CPAA/Manaus, and the Institute for Applied Botany/Hamburg University (Env.23) and additional plots with the... |
