Contrasting water use of two Eucalyptus clones across a precipitation and tempe...
Hubbard, Robert M.; Carneiro, Rafaela Lorenzato; Campoe, Otavio; Alvares, Clayton A. [UNESP]; Figura, Marco Aurélio; Moreira, Gabriela GonçalvesMade available in DSpace on 2020-12-12T01:33:29Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-11-01; Eucalyptus plantation productivity has increased 4-fold across Brazil as a result of improved genetic selection and intensive silviculture. However, the rate of productivity improvements is slowing and suggests increased production will require planting in areas that have never been previously planted w...
A distribuição de Weibull na descrição da estrutura diamétrica de Eucalyptus gr...
Figura, Marco AurélioO objetivo deste estudo foi o de testar o desempenho do uso do Método dos Momentos no ajuste da distribuição de Weibull e validar sua aplicação na descrição da estrutura diamétrica dos povoamentos, variando-se a estimativa do parâmetro de locação desta distribuição pelas técnicas: (1) percentuais do diâmetro mínimo, (2) regressão com atributos do povoamento e (3) compatibilização com a área basal. Os dados util...
Studies of Quantitative Relationships Among Dendrometric Variables and Carbon C...
Machado, Sebastião do Amaral; Urbano, Edilson; Jarschel, Barbara; Teo, Saulo Jorge; Figura, Marco Aurélio; Silva, Luis César Rodrigues daThis research aimed to determine dry weights and carbon contents by age, and by compartment of Mimosa scabrella trees, their correlations with other measured tree variables. The data for this research work came from 190 trees located in several counties of the Curitiba metropolitan region. Total height, crow height, stem height, DBH and crow diameter were measured of each one of the 190 trees. Every sample tree...
Behavior of the hypsometric relationship of Araucaria angustifolia in the fores...
Machado, Sebastião do Amaral; Mendes Nascimento, Rodrigo Geroni; Augustynczik, Alan Lessa Derci; Silva, Luís César Rodrigues da SilvaThe objective of this research was to test and select mathematics models for estimating total heigh (ht) and bole high (hb), as a function of DBH, as well as, to establish the dendrometric relationship between ht/hb. The data came from measurements of diameters (DBH), total height and bole height of all Araucaria angustifolia trees from an Ombrophylous Mix Forest fragment of 15,24 ha situated in the Botanical ...
Volumetric modeling for bracatinga (Mimosa scabrella) in bracatinga stands in C...
Machado, Sebastião do Amaral; Figura, Marco Aurélio; Silva, Luís César Rodrigues da; Téo, Saulo Jorge; Stolle, Lorena; Urbano, EdílsonThe objectives of this research were: to develop equations to estimate the stem and firewood volume of bracatinga (Mimosa scabrella Benth.); to evaluate the accuracy of the estimates having as a comparator the true volumes obtained by the xylometer method; to test the validity of Ahrens' (1981) published equation. In bracatinga stands, 384 trees were measured until a minimum diameter of 4 cm at the small end....
Growth dynamics of young trees of Araucaria angustifolia and Pinus taeda
Machado, Sebastião do Amaral; Figura, Marco Aurélio; Silva, Luís César Rodrigues da; Mendes Nascimento, Rodrigo Geroni; Quirino, Sandra Mara dos SantosThe objective of this research was to investigate the monthly growth rhythm of young trees of Araucaria angustifolia and Pinus taeda throughout the vegetative year and to establish its correlation with climatic variables. Monthly measurements of diameter and total height were carried out in one stand of A. angustifolia and two of Pinus taeda. Correlation matrices among the current monthly increments and the cli...
