Biomass production and nutrition aspects of plantation trees in Amazonia. Repositório Alice
NEVES, E.; AZEVEDO, C.P. de; GASPAROTTO, L.; DUNISCH, O.; BAUCH, J..
Establishment from a correlation between the nutrient content and the biomass of plantation trees. This was done in order to predict and to influence the wood quality to be expected already at an early growth stage. The development of biomass production of Ceiba pentandra (L.) Gaertn. (paineira) and Virola surinamensis (Rottb.) Warb. (ucuuba) was studied under monocultural conditions at an experimental field of Embrapa Amazonia Ocidental (Manaus-AM). Subsequently, the data were related to the nutrient supply after 45 and 46 months, respectively. It could be shown that the supply of the trees, especiallu with K and P, is restricted. The percentile content per dry weight biomass of the two macronutrients P and Mg deveases remarkably between 45 and 65 months...

Biomassa e conteúdo de elementos minerais nos compartimentos arbóreos de Ceiba pentandra (L.) GAERTN. Repositório Alice
NEVES, E. J. M.; REISSMANN, C. B.; DUNISCH, O..
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...

Comparative studies on morpho-physiological traits of six Amazonian species of Bellucia and Miconia (Melastomataceae) and implications for their ecological behaviour. Repositório Alice
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...

DUNISCH, O.; BAUCH, J.; GASPAROTTO, L.; NEVES, E.; AZEVEDO, C. de; LIMA, R. de; MORAIS, R. de.
This comparative study on environment-tree growth relationships of the high quality native tree species Swietenia macrophylla King (mogno) and Carapa guianensis Aubl. (andiroba) is part of the development of sustainable landuse systems on "terra firme" sites of the Central Amazon within the Brazilian-German research cooperation SHIFT. As to get information on the site demands and the growth characteristics of plantation systems of mogno and andiroba: (1) monoculture system, and (2) an enrichment system (both stablished in 1992 at the experimental site of the Embrapa Amazonia Ocidental, Manaus-AM). The water balance of the plantations was quantified by evaporation and transpiration/xylem flux measurements as well as the calculation of the water run-through...

Exogenous influences of the growth dynamics of plantation growth tree species of the central Amazon. Repositório Alice
DUNISCH, O.; BAUCH, J.; GASPAROTTO, L.; AZEVEDO, C. P. de; NEVES, E..
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...

High quality timber production in mixed plantations of the Amazon. Repositório Alice
DUNISCH, O.; GASPAROTTO, L.; AZEVEDO, C. P.; NEVES, E. M.; BAUCH, J..
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).

Influence of the water supply on the cambial growth dynamics of Swietenia macrophylla King under controlled conditions. Repositório Alice
MORAIS, R.; DUNISCH, O.; GASPAROTTO, L..
Study on the relationship of site factors (lighy, water, nutrient supply) of degraded areas on the growth dynamics and wood formation of native mahogany (mogno) in central Amazon. In this work the relationship of the water supply and the cambial growth dynamics of four years old mogno was investigated under greenhouse conditions. The results indicated the strong dependency of the cambial growth of mogno on a sufficient soil water supply.
