Carbon stock assessment and comparison in soybean plantations in Southwest Braz...
Guaraná Araujo, Emmanoella Costa; Pelissari, Allan Libanio; Dalla Corte, Ana Paula; Sanquetta, Carlos RobertoA significant proportion of deforestation in the Amazon rainforest is for the expansion of agriculture and livestock. Several studies have been dedicated to determining the carbon stock in natural forests, however agricultural areas are still poorly researched. This work aimed to quantify the above and belowground carbon stock (CS) in soybean plantations in the State of Rondonia, Southwest region of the Brazili...
ATRIBUTOS FÍSICO-HÍDRICOS E ESTOQUE DE CARBONO EM NEOSSOLO QUARTZARÊNICO SOB PL...
Pelissari, Allan Libanio; Amorim, Ricardo Santos Silva; Jordani, Sara Abreu; Guimarães, Pompeu PaesO objetivo do trabalho foi avaliar o efeito da colheita do eucalipto nos atributos físico-hídricos e no estoque de carbono em Neossolo Quartzarênico. O estudo foi conduzido em um povoamento de Eucalyptus urograndis com sete anos de idade, em Dom Aquino, MT, Brasil. As avaliações foram realizadas em dois períodos do ano (chuvoso e seco), e coletadas amostras de solo nas profundidades de 0–0,2; 0,2–0,4; 0...

Spatial correlation of soil chemical attributes with the development of teak in...
Pelissari, Allan Libanio; Caldeira, Sidney Fernando; Santos, Vanderley Severino dos; Santos, Joilson Onofre Pereira dosThe objective of this study was to investigate the spatial correlations of soil chemical attributes with the development of teak (Tectona grandis) in the city of Nossa Senhora do Livramento, Mato Grosso State, Brazil. It was allocated 46 permanent plots of 15 m x 30 m. From the stand it was obtained the mean annual values of diameter at 1.3 m above the ground and total height of second to ninth years of age. So...
Hypsometric relation for candeia (Eremanthus erythropappus) under different pla...
Araújo, Emanuel José Gomes de; Pelissari, Allan Libanio; David, Hassan Camil; Scolforo, José Roberto Soares; Netto, Sylvio PéllicoThe objective of this work was to adjust traditional models of hypsometric relations for homogeneous candeia stands, under different initial spacings. Ten models were adjusted for hypsometric relations. The assessment criteria obeyed the highest determination coefficient and the lowest standard error of estimate in percentage. The F test was also evaluated, as well as the significance of the regression coeffici...
Dendrometric relationship in fragments of pine stands in Minas Gerais
Araújo, Emanuel José Gomes de; Pelissari, Allan Libanio; David, Hassan Camil; Miranda, Rodrigo Otávio Veiga de; Péllico Netto, SylvioThe aim of this work was to adjust diameter distribution, hypsometric relation, taper and volume models to characterize the dendrometric relations on remaining fragments of Pinus sp. from stands of the 1970s, in the region where the Reserva de Desenvolvimento Sustentável Veredas do Acari is located, north of the state of Minas Gerais. The identification of the Pinus sp. fragments and its mapping was made. Biome...
Volumetric models for tropical pine in pure stand in Rondônia State, Brazil
Pelissari, Allan Libanio; Lanssanova, Luciano Rodrigo; Drescher, RonaldoThis study aimed to adjust volumetric models to tropical pines, in pure stand, in the municipality of Vilhena, Rondonia State. The data came from 20 felled trees of Pinus caribaea var. hondurensis and 10 Pinus tecunumanii trees with discs collected at fixed positions of 0.20 m, 0.70 m, 1.30 m and in distances of one meter along the stem, for later counting and measurement of the growth rings at ages from 4 to...
Análise de agrupamento e regressão não-linear aplicados ao crescimento in vitro...
Souza, Marcelo Dias de; Peres Filho, Otávio; Caldeira, Sidney Fernando; Pelissari, Allan Libanio; Dorval, AlbertoO estudo teve como objetivo avaliar o crescimento in vitro de Leucoagaricus gongylophorus em meio de cultura acrescidos com diferentes extratos de espécies vegetais, por meio da análise estatística multivariada de agrupamento de dados, além de determinar o comportamento do fungo por meio de equações de regressão não-lineares. O fungo foi inoculado em meio BDA acrescidos com oito extratos vegetais, além de dois ...
Form factor for young stands of Tectona grandis in State of Mato Grosso, Brazil
Drescher, Ronaldo; Pelissari, Allan Libanio; Gava, Fernando HenriqueThis study aimed to determine the artificial form factor and confection table form factor for teak in Brasnorte and Santo Antônio do Leverger, Mato Grosso State, Brazil. A hundred tress were measured and 162 were cubated in stands from 20 to 10 years of age. The volume was estimated using Smalian and form factors by the reason between the estimated and cylindrical volumes. Sixteen models of artificial the form ...
