EFEITO DA APLICAÇÃO DO POTÁSSIO, DO SÓDIO E DA DISPONIBILIDADE HÍDRICA NA DENSIDADE APARENTE A 12% DE UMIDADE DO LENHO JUVENIL DE ÁRVORES DE <i>Eucalyptus grandis</i>

Abstract: Expressiva área das plantações florestais de eucalipto de rápido crescimento no Brasil e em outras regiões do mundo encontra-se sob o efeito das mudanças climáticas, do estresse hídrico e da baixa fertilidade do solo, afetando o crescimento e a qualidade do lenho das árvores. O presente trabalho teve como objetivo avaliar a densidade aparente a 12% de umidade do lenho das árvores de Eucalyptus grandis com 12, 24 e 36 meses, com redução da precipitação pluviométrica e nutrição de K e Na. Os tratamentos foram de… Show more

“…However, the level I wood demonstrated high values of density variability (0.53 g.cm -3 ) across its entire profi le and were not concentrated at pith. High density values at pith are attached to reserve substance (carbohydrates) and crystals in parenchyma cells, according to Castro et al (2017).…”

“…Sette et al (2014a) describe the controversial effect of mineral fertilizers on Eucalyptus wood properties, indicating an increase and decrease in wood density. Studying the effect of potassium and sodium application on wood density of young Eucalyptus grandis trees, Sette et al (2014b) and Castro et al (2017) found lower density with lower fertilization. Barbosa et al (2014) reported higher wood density in Eucalyptus spp.…”

“…As mentioned earlier, the Brazilian forestry industry has an important role in the national economy and with a strategic position in the international market, due to the high productivity of Eucalyptus culture in comparison to other competitors. Also, the sector has been strengthening its activities, investing in mechanization of manual activities, use and allocation of effective fertilizers and herbicides (Castro et al, 2017;Gonçalves et al, 2017).…”
