“…The four willow clones produced similar yields in dry biomass compared between them; but, excluding the site n° 7 where they has been damaged from hares and wild rabbits, they produced higher yields compared to the best performing poplar clones. These figures are comparable to those recently reported for SRC with poplar and willow in Northern Europe [24,25], Canada [26] and Italy [27,28].…”

Data collected from 183 poplar and 102 willow SRC experimental plots, located in Central-North Italy, were subjected to stepwise regression analysis to acquire information on the environmental factors affecting plant survival and productivity in the first two-year rotation cycle. Nine Populus ×canadensis Mönch, eight P. deltoids Bartr. clones and four hybrids of Salix matsudana Koidz were included in analysis. Independent variables were: annual and seasonal water availability (rainfall and irrigation), annual mean air temperature, soil texture, pH, N and organic matter content, planting density and management intensity. Dependent variables were: a) mean annual yield during the first two-year rotation cycle in tons per hectare per year of dry matter (Odt·ha ); b) plant survival at the end of the second year from planting (%). Water availability resulted the main variable driving plant survival and biomass production in both poplar and willow clones. Water availability appeared to be the principal factor affecting the establishment of poplar and willow energy plantations in the Po valley. Possible variations in the rainfall regime consequent to climate changes could seriously influence land suitability to SRC. Experimental data also indicate that choice of planting density may increase the biomass yield during the first two-year especially with P. deltoides clones. © Versita Sp. z o.o.

Poplar and willow SRC plantations can produce large amounts of dry matter in a relatively short time (e.g. 1-2 years) maintaining their yield capacity throughout many years [1].During the last 5 years about 6000 hectares of energy plantations (Short-Rotation-Coppices, SRC) have been established in Italy, mainly in the Po valley, where biomass thermoelectric power plants are under construction, and the Regional Programs for Rural Development included a series of financial incentives to support the establishment and maintenance of SRC. The planted species were those recommended for the North and Central Italy by the National guidelines for energy plantations [2,3] namely poplars (Populus Cent. Eur.

“…Only few of the Populus species are of high scientific and economic importance, and serve as source material for breeding purposes (Licht and Isebrands, 2005;Walle et al, 2007). Important characteristics of some interspecific hybrids are high growth rates and broad applicability ranging from wood and paper to energy production (Dickmann and Stuart, 1993 (Fladung et al, 2012) and the availability of huge genomic resources (Stettler et al, 1996;Stanton et al, 2010).…”

Populus trichocarpa and P. deltoides are the only Populus species known to date to have a publicly available nuclear genome sequence that has been assembled to chromosomes and annotated (https://phytozome.jgi.doe.gov/). Here we focus on the clone INRA 717-1B4, a female P. tremula x P. alba (P. x canescens) interspecific hybrid that is universally used by scientists worldwide as a tree model in transgenic experiments. The already available INRA 717-1B4 nuclear genomic resource (v1.1 of sPta717 at http://aspendb.uga.edu/index.php/databases/ spta-717-genome) presents only INRA 717-1B4 genomic regions with high similarity to the P. trichocarpa genomic reference sequences. We assembled draft genomic scaffolds by a combination of de novo assembly with reference-based assembly using 30x resequencing NGS data (Illumina MiSeq® and Ion Torrent Ion PGM™) of INRA 717-1B4. In total, 419,969 scaffolds of length larger than 500 bp were generated. The mean length of the scaffolds is 2,166 bp and the size of the largest scaffold 84,573 bp. The N50 contig length is 3,850 bp when considering contigs larger than 1,000 bp. Probably due to the high level of heterozygosity of this interspecific hybrid, the accumulated scaffold length is with 0.9 GB about twice the expected size of the haploid nuclear genome. DNA sequences of the genomic scaffolds of INRA 717-1B4 are publicly available for Blast analyses and download via the new INRA web portal at https://urgi. versailles.inra.fr/Species/Forest-trees/Populus/Clone-INRA-717-1B4/. This new genomic sequence resource will complement the already available INRA 717-1B4 resources and will facilitate the future optimization of genetic transformation experiments to discover gene function.

“…Moreover, many poplar clones and species showed to have a high energy potential and to be able to grow in marginal lands and drought conditions (Hansen, 1991;Makeschin, 1994). Many studies have been performed on biomass productivity and quality, management intensity, economic balance and energy aspects of poplar SRF (Yue et al, 1999;Bonari et al, 2004 a,b;Vande Walle et al, 2007;Karp and Schield, 2008;Lemus et al, 2008;Guidi et al, 2008Guidi et al, , 2009Nassi o Di Nasso, 2010).…”

In the last decade, the change of energy concept induced by global warming and fossil fuel depletion together with the advances in agriculture towards a multifunctional and a more sustainable use of rural areas promoted the development of biomass crops. In this regard, Populus is largely utilised in short-rotation forestry (SRF), as it is known to be a fast-growing tree, producing large yields and having a high energy potential. Most studies focused on economic-productive and energetic aspects of Populus plantations, whereas their impact on soil quality and health have been poorly investigated. In this study, the main soil chemical parameters, microbial biomass and activity were assessed aiming at evaluating the impact of Populus SRF under one, two and three-year cutting cycles (T1, T2 and T3) in comparison with an intensive food cropping system (wheat-soybean rotation, WS). In addition, arbuscular mycorrhizal (AM) fungal inoculum potential was measured using root colonisation (RC) and number of entry points (EP). In the 0-10 cm soil depth, pH, phosphorus (P), total nitrogen (N) and soil organic carbon (SOC) were significantly affected by the management. In comparison with WS, Populus SRF treatments produced significant pH decreases together with N and SOC increases, these last ones ranging from 11% to 34% and from 21% to 57%, respectively. Under T3 soil pH decreased of 0.25 units, while P, N and SOC increased of 10%, 34% and 57%, respectively, in comparison with WS. Microbial biomass and soil respiration under SRF showed also mean increases of 71% and 17%, respectively. Under SRF treatments, Lolium perenne, commonly observed in all field plots, was more than twofold colonised by AM fungi in comparison with WS, while the number of EP, observed on Lactuca sativa used as a test plant, showed values ranging from 8 to 21 times higher. The present study shows the potential of a Populus SRF to improve soil chemical, biochemical and biological quality parameters in comparison with an intensive food cropping system.
