MODELOS DE AFILAMENTO E FORMA DOS FUSTES DE EUCALIPTO, EM DIFERENTES QUALIDADES...
Téo, Saulo Jorge; Miguel, Eder Pereira; Nascimento, Rodrigo Geroni MendesEste trabalho teve como objetivo ajustar e selecionar modelos de afilamento para estimar diâmetros, volume por seção e volume acumulado com casca, ao longo do tronco de árvores de Eucalyptus grandis Hill ex. Maiden, em Rio Verde – GO, para estudar a forma dos fustes das árvores em diferentes classes de sítio. Foram cubadas rigorosamente pelo método de Smalian, 812 árvores em um povoamento florestal cuja densida...
PHYTOSOCIOLOGY OF A FRAGMENT OF ARAUCARIA MOIST FOREST, IRANI, SC, BRAZIL
Souza, Gabriela Fernanda; Téo, Saulo Jorge; Guareschi, Daiane GiseleFITOSSOCIOLOGIA DE UM FRAGMENTO DE FLORESTA OMBRÓFILA MISTA, EM IRANI, SC, BRASILEste trabalho tem como objetivo principal determinar a estrutura fitossociológica, em fragmento de Floresta Ombrófila Mista, em Irani, SC. Foram instaladas 30 parcelas de 500 m2, em processo de amostragem sistemático em dois estágios. Foram amostrados os indivíduos com circunferência à altura do peito maior que 30 cm. Foram calcula...
Above ground pruning, aiming better quality of seedlings of Pinus taeda, in Caç...
Téo, Saulo Jorge; Marcon, Alan; da Costa, Reinaldo HoinackiThe objective of this paper was to evaluate the effects caused by the above ground pruning over the survival, height (h), neck diameter (dn) and h/dn relation, of Pinus taeda L. seedlings, in the municipal district of Caçador, Santa Catarina State, Brazil, aiming to obtain seedlings of better quality. Six different types and intensities of pruning were tested. The data were analyzed by the variances homogeneity...
ESTRUTURA DA REGENERAÇÃO NATURAL SUJEITA À PECUÁRIA EXTENSIVA NA REGIÃO DE CAÇA...
Téo, Saulo Jorge; Fiorentin, Luan Demarco; Schneider, Chaiane Rodrigues; Da Costa, Reinaldo Hoinacki; Batista, SannyO objetivo deste trabalho foi analisar o efeito da pecuária extensiva sobre a regeneração natural em área de preservação permanente de Floresta Ombrófila Mista na região de Caçador, SC. Foi mensurado o diâmetro do colo (10 cm) e a altura total de todos os indivíduos de regeneração natural que apresentaram altura acima de 30 cm e circunferência à altura do peito menor que 15,7 cm. Foram avaliados os parâmetros f...
Dynamics of the diameter distribution of Pinus taeda stands, in the region of C...
Téo, Saulo Jorge; Rocha, Samara Pozzan da; Bortoncello, Aline Cristina; Paz, Rafaela Antunes; Costa, Reinaldo Hoinacki daThe objective of this work was to fit the probability density functions Normal and SB, to describe the changes, with age, in the diameter distribution of loblolly pine (Pinus taeda) stands, in the region of Caçador, Santa Catarina State, Brazil. The data came from permanent and temporary plots, with ages ranging from 5 to 11,9, grouped in age classes with intervals of 1 year. The probability density functions w...
Micronutrient Modeling for Mimosa scabrella Bentham in the Curitiba Metropolita...
Téo, Saulo Jorge; Machado, Sebastião do Amaral; Figueiredo Filho, Afonso; Reissmann, Carlos BrunoThe objective of this research was to model the micronutrient content for Mimosa scabrella Benthamabove-ground biomass, aiming to obtain equations to estimate micronutrient content using tree dimensions asindependent variables. Data came from 25 trees sampled in native Mimosa scabrella stands in the northernCuritiba metropolitan region, Parana state, Brazil. The trees were cut down and their components were sep...
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...
