The objective of this study was to evaluate the phytosociology and timber potential in the southeast of Flona Tapajós, state of Pará. The cluster sampling process was adopted with 36 primary units systematically distributed. These units were composed of four secondary units measuring 20 x 250 m. All trees with DBH > 10 cm were measured, but different size classes and subsamplings were considered. The phytoso...
O objetivo dessa pesquisa foi avaliar a estrutura populacional e do potencial econômico de castanhais nativos no Baixo Rio Tapajós, estado do Pará. Foram usados dados de três censos florestais (A, B e C), os quais registraram apenas árvores com DAP ≥ 30 cm. A estrutura diamétrica e o padrão espacial foram avaliados por meio de histogramas e da função K de Ripley, respectivamente. O potencial econômico foi estim...
Indole-3-butyric acid (IBA) is a plant growth regulator widely used to induce rooting of cuttings. The objective of this work was to evaluate the effect of different concentrations of IBA and of two cuttings types in vegetative propagation of Senna alata (Linnaeus) Roxburgh. The experiment was established in a completely randomized design with four repetitions, in factorial 4 x 2, using four concentrations of A...
