Última Effects of different spacings on heartof- palm production from peach-palm planted in the coastal region of the state Paraná – Brazil – 1ST Harvest PFB - Pesquisa Florestal Brasileira Neves, Edinelson José Maciel; Santos, Álvaro Figueredo dos; Martins, Emerson Gonçalves; Ahrens, Sérgio; Kalil Filho, Antonio Nascim. An experiment was established in Paranaguá, located in the costal region of the State of Paraná, in southern Brasil, in order to evaluate commercial yield of hearth-of-palm produced by Peach-Palm (Bactris gasipaes) established under the following four different initial spacings: T1 2x1m (5000 seedlings/ha); T2 3x1m (3333 seedlings/ha); T3 1,5x1x1m (8000 seedlings/ha); and T4 2x1x1m (6666 seedlings/ha). Mineral fertilizers (NPK) were applied at planting as well as subsequently. Results obtained by the time of the first cutting, 24 months after planting, allowed the following conclusions: a) the quantities of the NPK fertilizer used promoted changes in the chemical soil characteristics; b) commercial yield of hearth-of-palm improved as a function of stand...

Ano: 2003 URL: http://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1619 Pruning effects on growth ring thickness and wood density of Pinus taeda L. PFB - Pesquisa Florestal Brasileira Pereira, José Carlos Duarte; Ahrens, Sérgio. Effects of pruning on growth ring thickness and density were studied in young trees of Pinus taeda L. A reduction in growth ring thickness and an increase in density were found only in the first year after the most severe pruning, in which branches were removed up to 3,0 m height. Pruning had no effect on wood density in the following years. On the other hand, there was a significant increase in ring thickness after the initial reduction in the first year, suggesting the existence of a negative trophic balance in the lower branches. If properly applied, pruning can improve both growth process and wood quality of the main stem.
