Compartimentalización de la biomasa aérea de Grevillea robusta A. en función a la densidad inicial de plantación = Aboveground biomass allocation of Grevillea robusta A. based on initial planting density
Planting density at a given age is a reliable indicator of the degree of a site’s arboreal cover and thus it represents the structure of the forest stand.

| description | Planting density at a given age is a reliable indicator of the degree of a site’s arboreal cover and thus it represents the structure of the forest stand. The objective of this paper was to assess the initial planting density’s effect on aboveground biomass accumulation in an 18-year old Grevillea robusta plantation. The test was conducted in Posadas, Misiones (Argentina), with 4 initial planting densities (162, 375, 750 and 1500 plants/ha). Biomass accumulation was analyzed in the shrub, herbaceous, forest floor and trees strata (leaves, branches, stem and bark). In the case of trees, the effects of the treatments were studied in individuals and in the stands. The total understory biomass presented significant differences among treatments. Biomass allocation varied leading to a higher presence of dead branches and shrub biomass at higher planting densities. The herbaceous stratum had a higher biomass accumulation with the lowest planting density treatment. Larger spacing resulted in larger individual diameter but the highest stem biomass accumulation per hectare was observed with the smallest spacing. |

A densidade de plantação a uma determinada idade é um indicador confiável da ocupação arbórea de um local, representando assim a estrutura das florestas. O objetivo deste estudo foi avaliar o efeito da densidade de plantio inicial no acúmulo da biomassa de plantações de Grevillea robusta a os 18 anos de idade. O ensaio foi conduzido em Posadas Misiones, Argentina, com 4 densidades de plantio iniciais (162, 375, 750 e 1500 plantas / ha). O acúmulo da biomassa foi analisado nos estratos arbustivo, herbáceo, piso florestal e arbóreo (folhas, galhos, tronco, casca). Nas árvores é considerado tanto o efeito sobre os indivíduos e sobre o sítio. A biomassa total do sub-bosque apresentou diferenças significativas entre os tratamentos. A distribuição da biomassa variou resultando em aumento da presença de galhos mortos e biomassa do estrato arbustivo em densidades de plantio superiores. A acumulação da biomassa herbácea foi maior no tratamento da plantação da menor densidade. O maior espaçamento resultou num maior diâmetro dos indivíduos, mas a maior acumulação da biomassa do fuste por hectare foi em espaçamentos menores. EEA Montecarlo Fil: Barth, Sara Regina.
