Um importante desafio para a pesquisa florestal na Amazônia é o de encontrar formas de reflorestar áreas degradadas com a utilização de um maior número de espécies nativas e identificar espécies tropicais comercialmente atrativas adaptadas a plantios a pleno sol. Este trabalho teve como objetivo avaliar o crescimento inicial em diâmetro e altura de seis espécies nativas da Amazônia em um ensaio preliminar de espécies. Os dados para a realização deste estudo foram oriundos de remedições de 72 árvores em um período de 9 anos. As espécies selecionadas para este trabalho foram a cupiúba (Goupia glabra), o cumaru (Dipterix odorata), a andiroba (Carapa guianensis), a castanheira-do-brasil (Bertholletia excelsa), o pará-pará (Jacaranda copaia) e a tatajuba (Bagassa guianensis). As curvas cumulativas de crescimento em diâmetro e altura foram obtidas pelo ajuste da função de Chapman-Richards. Apesar da pouca idade dos plantios, obteve-se bom ajuste da função para as espécies estudadas, sendo o pará-pará a espécie que apresentou maior crescimento em diâmetro e altura em todas as idades. A análise do incremento médio anual em diâmetro indicou que, com exceção da cupiúba, pode-se esperar incrementos médios superiores a 2 cm, mediante a adoção de espaçamentos e programas de desbaste adequados.

“…At least in the case of Acacia mangium, this pattern was corroborated by the high rate of stem bifurcation, which implies intense competition for light. The rapid growth in height of Acacia mangium, also reported by Miranda and Valentim (2000), may be influenced by the high capacity of this species to explore the nutritional pool in the soil, which causes soil acidification due to cation depletion (Yamashita et al 2008).…”

Planting of forest species of timber interest helps to reduce the deforestation pressure on the Amazon forest, promotes sustainable development of the producing region and generates ecological benefits. The objective of this work was to evaluate the survival rate and growth of four native (Swietenia macrophylla, Parkia decussata, Dipteryx odorata and Jacaranda copaia) and one exotic (Acacia mangium) species in monospecific plantations (spacing of 2 x 2 m) established on areas previously used for grazing, in Itacoatiara, State of Amazonas, Brazil. When the trees were four years old, we collected biometric data )], e dados qualitativos obtidos por diagnose visual [taxa de sobrevivência (S; %), estado nutricional (NS, G: bom; D: deficiente; %) e estado fitossanitário (PS, S: satisfatório; NS: não-satisfatório; %). Para cada espécie considerouse três parcelas de 128 m 2 , cada uma com 32 plantas. Jacaranda copaia, seguida de Dipteryx odorata e Parkia decussata, foram as espécies mais recomendadas para o plantio em áreas com condições edafoclimáticas semelhantes às do presente trabalho, devido ao seu melhor desempenho para a maioria das variáveis.

“…First, there is little knowledge of successful techniques and candidate species. While in Central America live fencing is a common practice among farmers, in Brazil this practice is incipient (Miranda & Valentim ; Nascimento et al ), and there is little information about the local native species and proper techniques for propagation by large cuttings. Second, propagation by cuttings causes undesired genetic homogeneity, because many cuttings are taken from a few trees.…”

Tropical dry forest tree species are recognized for their high resprouting ability after disturbance. We tested whether species that commonly produce root and stem suckers can be propagated by large stem and root cuttings, a useful method for landscape restoration programs. We performed four experiments: (1) In a greenhouse, we tested the propagation of six species using large stem cuttings collected from early successional sites. We used the following treatments: (i) dry season collection and planting; (ii) dry season collection, storage in humid soil, and wet season planting; (iii) wet season collection and planting; and (iv) wet season collection and planting after treatment with commercial NAA auxin. (2) Stem cuttings of Myracrodruon urundeuva were planted in a pasture during the rainy season after either NAA, IBA, or no auxin treatment. (3) As a control experiment, we also planted cuttings of Spondias mombin, a species known for successfully regenerating from cuttings. (4) Root cuttings of six species were collected in recently plowed pastures and planted in the greenhouse with and without treatment with NAA auxin. No root cuttings rooted. Only M. urundeuva and Astronium fraxinifolium stem cuttings rooted. Maximum success was obtained for stem cuttings collected and planted in the dry season (23%). Only 13% of M. urundeuva had sprouted by the 15th month of the field experiment. As a result, large cuttings are not recommended for propagation of the studied species. Future studies should include development of suitable methods of root harvesting and prospection of traditional knowledge for species selection.
