According to some studies, the use of forest biomass for the generation of electric power and/or heat would result in a significant reduction in the emission of greenhouse gases. This would happen even in the case of soils substitution that currently have an agricultural use although its implementation would require more studies on the environmental impact that they could have in each particular case. In this study, the potential of electric power production is evaluated with several species of Eucalyptus planted in short rotation forestry systems. Three species were evaluated: E. benthamii, E. dunnii and E. grandis in four spacings: 3×1.5 m, 3×1 m, 3×0.75 m, 3×0.5 m, in two sites in the northern and western areas of Uruguay during a period of 76 and 75 months, respectively. During this period, the following parameters were evaluated: higher heating value, wood density, energy density and energy yield per hectare and per year. The results obtained show that the heating value changes slightly with the planting density and age. The average of higher heating values were 19,787 versus 19,454 J g-1 and 19,867 versus 9909 J g-1for the planting densities of 2220 versus 6660 trees ha-1 at Paysandú and Tacuarembó, respectively, at 76 months. Higher heating value increased from 19,665 to 19,745 J g-1 at 18 months to 19,740 and 19,914 J g-1 at 76 months for Paysandú and Tacuarembó, respectively. The wood density, depending on the site, is affected by age, species and planting density. On average, wood density increased (only at Paysandú) from 0.405 g cm-3 at age 18 months to 0.497 g cm-3 at age 76 months. There is a negative relationship between the heating value and the wood density. The energy yield is basically explained by the production of biomass. At Tacuarembó, a stronger relationship between energy production and planting density is obtained (1012 vs. 636 MW ha-1 for 6660 and 2220 trees ha-1, respectively) compared to the Paysandú site (1093 vs. 912 MW ha-1 for 6660 and 2220 trees ha-1, respectively). Harvest times are different in each site depending on the IMA values obtained.

ABSTRACT.
The allelopathic nature of adult Parthenium hysterophorus L. (parthenium weed) plants, suppressing the growth and development of its near neighbours, has been implicated in its success as an important invader around the world. This study for the first time, evaluates the allelopathic potential of parthenium weed seedlings, species using the ?plant box? method (10). Results showed a species-specific response,often with the growth of native species being more affected than introduced speciesand root growth more affected than shoot growth. The native grasses [curly windmill grass (Enteropogon acicularis L.; 59% inhibition) and cotton panic grass (Digitaria brownii L.; 54% inhibition)] were the most affected, while the introduced [Rhodes grass (Chloris gayana L.; 0% inhibition), buffel grass (Cenchrus ciliaris L.; 8% inhibition) and siratro (Macroptilium atropurpureum (DC.) Urb.; 9% inhibition)] were
the least affected in their root growth. These results suggested that parthenium weed is capable of interfering with the growth of neighbouring seedlings even at very early
stages of growth. The response found for buffel grass may partially explain why this introduced pasture grass has been found successful in suppressing the growth of
parthenium weed in the field. |
