Summary: | Poplar (Populus spp.) is a fast-growing species in temperate conditions,
with potential to substitute fossil fuels by obtaining energy from
biomass. The aim of this work was to study the productivity of 6 hybrid
poplar clone from a hilly region of NE Romania, after a growing season of
4 and, respectively, 5 years. Rods were used as planting material, planted
at a density of 2667 trees per ha, with between-row spacing of 3 m and
interior-row distances of 1.25 m. Generally, significant differences appear
between clones, for all analysed biometric characteristics (p≤0.05). Results
show that, in the fifth growing season, diameter increases on average with
15.1%, reaching 11.89 cm, height increases in average with 13.9%, reaching
11.89 m, and volume increases with 33.3%, reaching 0.172 m3. The total
biomass after 4 years vegetation varies from 32.8 t/ha to 39.4 t/ha, and after
5 years from 47.7 t/ha to 60.2 t/ha, having an average increase in the latest
growing season of 35% and an average yield of 11.3 t/ha/year. The most productive
clones in the given growing conditions and crop characteristics are
the clone Pannonia after 4 growing seasons and the clone AF6 after 5 years. |
