Resumen

EUFRADE-JUNIOR, Humberto de Jesus; WAGNER BALLARIN, Adriano; VILLAMAGUA-VERGARA, Gabriela Carolina  y  SEBASTIAO GUERRA, Saulo Philipe. Effect of silvicultural management on wood density from short rotation forest systems. Maderas, Cienc. tecnol. [online]. 2017, vol.19, n.3, pp.285-292.  Epub 16-Mayo-2017. ISSN 0718-221X.  http://dx.doi.org/10.4067/S0718-221X2017005000024.

The short rotation forest systems are managed under conditions that differ from conventional management with greater density planting and fertilizer levels, also shorter harvesting cycles. Even today, there are few studies about the quality of the biomass produced on these systems. This work aimed to analyze the effect planting spacement and fertilizing levels in the stem basic density of Eucalyptus urophylla × Eucalyptus grandis (clone C219) from short rotation system at two years of age. The results showed that the density was affected significantly by planting spacement and fertilization. It was higher for the lower planting spacement (2380 trees ha-1) about 375 kg m-3 and greater fertilizer level (140 g plant-1) to 379 kg m-3. The values found were close to other forest species managed in short rotation systems for bioenergy in the world.

Palabras clave : Biomass; Eucalyptus; fertilization; planting density; silviculture.
