Summary: Spacing of planting is one of the most important silvicultural decisions to be made during implementation of forest stands. The objective of this study was to evaluate the influence of spacing of planted trees on biomass production and solar radiation use efficiency in a Eucalyptus forest plantation in southern Brazil. A field experiment was conducted from September 2008 to September 2017 in the city of Frederico Westphalen, State of Rio Grande do Sul, Brazil. In this study, we evaluated the influence of the spacing of trees on solar radiation use efficiency, interception of solar radiation, leaf area index, biomass yield, and partitioning in the Eucalyptus forest plantation. The conversion efficiency of the photosynthetically active radiation intercepted in the biomass was manipulated by changing the spacing of the trees, and the highest conversion efficiency was 0.0062 kg MJ−1 for the 2.0 × 1.5 m planting spacing. Eucalyptus trees grown on the 2.0 × 1.0 m planting spacing showed the highest biomass yield with 961.4 Mg ha−1, showing that the most efficient plants in the conversion of photosynthetically active radiation are not always the most productive. As a result, the hypothesis of this study was confirmed. Forest managers can accelerate growth and increase the production of forest biomass by adequately manipulating the spacing between the trees.

O objetivo deste trabalho foi avaliar a influência do espaçamento de plantios na produção de biomassa e a eficiência do uso de radiação em um plantio florestal de eucalipto no sul do Brasil. Um experimento de campo foi conduzido de setembro de 2008 a setembro de 2017 na cidade de Frederico Westphalen, RS, Brasil. Para atingir o objetivo do estudo, avaliou-se eficiência no uso da radiação solar, interceptação da radiação solar, índice de área foliar, rendimento de biomassa e partição. A eficiência de conversão da radiação fotossinteticamente ativa interceptada na biomassa foi afetada pelo espaçamento de plantio e a maior eficiência de conversão foi de 0,0062 kg MJ−1 para o espaçamento de 2,0 x 1,5 m. Além disso, as árvores de eucalipto cultivadas no espaçamento de 2,0 × 1,0 m apresentaram o maior rendimento de biomassa com 961,4 Mg ha−1, demonstrando que nem sempre as plantas mais eficientes na conversão de radiação fotossinteticamente ativa são as mais produtivas. Portanto, a hipótese deste estudo foi confirmada, uma vez que os produtores florestais podem acelerar o crescimento e aumentar a produção de biomassa florestal, utilizando espaçamento de plantio adequado.Instituto de Pesquisas e Estudos Florestais - IPEF2021-07-30T17:48:01Z2021-07-30T17:48:01Z2020-12info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfNARDINI, C. et al.
