“…Aboveground biomass in poplar plantations or forestry system (FRS) and agroforestry systems (AFS) has been widely studied around the world (Laureysens et al, 2004;Zabek and Prescott, 2006;Fang et al, 2007;Christersson, 2010;Fortier et al, 2010;Truax et al, 2012;). In spite of crucial role of belowground parts for woody biomass production and carbon sequestration in soil (Berhongaray et al, 2015), fewer or disproportionate studies have evaluated the belowground biomass of these systems (Fortier et al, 2013).…”

In poplar, one of the most used species of forestry and agroforestry, below ground biomass allocation plays an important role in providing anchorage as well as efficient nutrient and water distribution channel. Available literature on this aspect is not enough in hybrid Poplar, Populus euramaricana I-214. Therefore, the study was aimed at finding how this species developed its root system and how much belowground biomass was allocated in Forest System (FRS) and Agroforest System (AFS). This was done using soil excavation and root coring methods. Coarse roots were distributed in all directions but their number and proximal cross section area (CSA) were not uniform. In the case of AFS tree maximum CSA was distributed in the south and south-west direction while in FRS it was in the north-east and south-east direction. Fine roots were observed throughout the rooting zone along with coarse and medium roots up to a maximum depth of 2.4 m in FRS and 2.8 m in AFS. Total belowground biomass was higher in AFS tree (130 kg tree -1 ) than FRS tree (120 kg tree -1 ). But on hectare basis FRS accumulated (24.5 Mg ha ). However, if practiced in surplus agriculture area and considered the system as a whole, AFS allows grain production in lieu of some biomass deficit.

“…Perinet (1999) reported yields ranging from 8 to 12 m 3 /ha·yr in Quebec. The maximum yield observed is 40 m 3 /ha·year in Southern Quebec, with 2222 stems/ha (Fortier et al 2010). Mean annual increment in hybrid poplar plantations at age 7 to 15 years has also been reported to be over 2.6 times higher than that of unmanaged natural stands at age 55 years in southern Ontario (Zsuffa 1973).…”

The physical and mechanical properties of poplar clones largely determine their suitability for various end-uses, especially for high valueadded applications. The main objective of this study was to determine the clonal variation of selected physical and mechanical properties of seven hybrid poplar clones grown at three sites in southern Quebec, Canada. Five trees per clone were randomly sampled from each site for wood properties measurement. Site had a significant effect on all measured properties except radial shrinkage. All properties of hybrid poplar wood showed significant interclonal variation, indicating the possibility of identifying clones with superior wood properties, especially for density, flexural modulus of rupture, and ultimate crushing strength. High heritability values for the studied properties indicated that these properties are under moderate to high genetic control. The genetic gain for these wood properties ranged from 2.0% to 13.5%.

“…It is expected that perennial energy crops should be highly productive and their biomass should be characterized by a high lower heating value and a low content of ash. Perennial crop species are divided into the ones yielding wood, semi-wood and straw biomass which differs in its quality parameters as solid fuel (Redei et al, 2008;Stolarski et al, 2008;Kollas et al, 2009;Fortier et al, 2010;Przyborowski et al, 2012). The thermophysical and chemical characteristics of biomass from different crop species are also affected by the harvest time and the course of weather during that period .…”

A b s t r a c t. This paper presents analyses of the thermophysical and chemical properties of eleven perennial crop species harvested in one-year rotation cycles. The crops included four species grown for biomass in the form of straw, five species producing semi-wood biomass, and two species yielding wood biomass. The research comprised three consecutive crop harvests. In each harvesting season, biomass samples for analyses were taken on six dates at one-month intervals. Thermophysical and chemical properties of the biomass were significantly differentiated within the main experimental factors and their interactions. The biomass produced by Virginia mallow had the best quality parameters as solid fuel. In fact, it achieved the lowest water content and the highest lower heating value during all of the analyzed seasons and harvest dates. The biomass of the species yielding straw or semi-wood products attained better quality as solid fuel on later harvest dates. In turn, the quality of willow biomass remained practically unchanged between the harvest dates.K e y w o r d s: biomass, perennial crops, lower heating value, ash content, chemical composition
