“…& A.Gray ex Hook. Considerable breeding efforts have produced a number of fastgrowing poplar cultivars (Stanton et al 2010;Karp et al 2011); these are derived almost entirely from interspecific crosses (Benetka et al 2014). In Europe, new poplar hybrids are mainly derived from crosses between the s. Aigeiros species P. deltoides and P. nigra, and called P. × canadensis Moench (Bisoffi and Gullberg 1996), or between the s. Aigeiros species P. nigra with the s. Tacamahaca species P. maximowiczii (Stanton et al 2010).…”

“…Under Polish conditions, such plantations are managed on short cycles, usually 1-10 years (the time interval between felling), or medium rotations (the interval between planting and replanting) of 15-25 years (Zajączkowski 2013), using genera such as willow (Salix L.) and poplar (Populus L.) (Herve and Ceulemans 1996;Verwijst 2001;Stolarski 2009;Benetka et al 2014) and, recently, black locust (Robinia pseudoacacia L.) (Lambert et al 2010;Wojda et al 2015). Many researchers also recommend growing such species (especially poplars) on cycles no shorter than 5-6 years (Fang et al 1999;Alig et al 2000;Boelcke and Kahle 2000).…”

Background: Renewable energy sources such as biomass are an important aspect of the energy policy of the European Union. As the use of 'full-value wood' for energy purposes has been restricted, short-rotation forestry may be an alternative source of woody biomass. In Poland, the most promising genus is poplar (Populus spp.). Methods: Ten poplar cultivars from the Aigeiros or Tacamahaca sections of the genus Populus were compared in 5-and 6-year rotations for biomass components and yields. Additional aims were to preliminarily (a) identify a suitable rotation length and (b) evaluate the sprouting capacity of various cultivars in the climate of northern Poland. The following variables were measured: diameter at breast height (DBH), height, survival rate, single-tree dry mass, crop biomass production, and sprouting ability. Results: The cultivars 'NE-42' and 'Fritzi Pauley' showed the best growth characteristics (DBH and height) and highest biomass production (7.6 and 7.7 t ha −1 year −1 , and 5.2 and 6.9 t ha −1 year −1 , respectively, for cultivars in the 5-and 6-year cycles). These cultivars were also distinguished by a large number of coppice shoots and a high shoot length. Eight cultivars did well enough to produce worthwhile data, and five of these gave higher biomass production (t DM ha −1 year −1 ) during the 6-year, as opposed to the 5-year cycle. Of the eight cultivars analysed, 'AF-8' had the poorest growth parameters and produced two thirds less dry biomass than either the 'NE-42' or 'Fritzi Pauley' cultivars. Data for two Italian cultivars ('AF-6' and 'MON') were not analysed because of their cold tenderness and their high mortality. Conclusions: Rotation length is important for biomass production in energy plantations. Most of the tested poplar cultivars gave higher biomass productivity over an initial 6-year cycle than over a 5-year one. Our preliminary results suggest that the 'NE-42' and 'Fritzi Pauley' cultivars performed best among those tested. Both of these have been tested previously in Poland in medium and long rotations. The data indicate the importance of testing cultivars under local climatic conditions before planting on a commercial scale.

“…In SRC systems, faster canopy closure and increased growth rates of sprouts from an established root system result in enhanced productivity of coppiced versus noncoppiced tree stands . Substantial genotypic variation exists in aboveground woody biomass productivity (AGWB) of SRC cultures in poplar (Ceulemans & Deraedt 1999, Dillen et al 2011, Paris et al 2011, Benetka et al 2014). Variation in AGWB has been explained by variation in light interception, in biomass allocation, in leaf physiological factors related to RUE or in a combination of the aforementioned (Cannell et al 1988, Green et al 2001, Tharakan et al 2008, suggesting inconclusive results on the relative importance of productivity determining factors in SRC.…”

© iForest -Biogeosciences and Forestry IntroductionEnergy security and greenhouse gas emission reductions are major challenges to meet the global energy demand and to mitigate climate change (IPCC 2014). In the light of these global concerns bioenergy could play a crucial role to achieve the EU's energy and climate targets (European Council 2009). The cultivation of lignocellulosic biomass, mostly poplar and willow in short rotation coppice (SRC) systems, has a high potential for the production of renewable electricity and the generation of "green" heat (Fischer et al. 2010). Despite the long-term experience with the commercial production in northern Europe (Rosenqvist et al. 2000, Langeveld et al. 2012, the implementation of SRC as a renewable energy crop is limited in European agriculture (AEBIOM 2010, Dimitriou et al. 2011, Don et al. 2011.Productivity is determined by light interception and by the efficiency of converting the intercepted radiation into biomass, i.e., the radiation use efficiency (RUE), as reported for both herbaceous (Sinclair & Horie 1989) and woody (tree) species (Cannell et al. 1988, Medlyn 1998. The crop's capacity to intercept radiation is determined by its photosynthetic area, generally assessed via the leaf area index (LAI), which is linearly related to the biomass production in poplar and willow plantations (Larson & Isebrands 1972, Cannell et al. 1988, Taylor et al. 2001a. In SRC systems, faster canopy closure and increased growth rates of sprouts from an established root system result in enhanced productivity of coppiced versus noncoppiced tree stands . Substantial genotypic variation exists in aboveground woody biomass productivity (AGWB) of SRC cultures in poplar (Ceulemans & Deraedt 1999, Dillen et al. 2011, Paris et al. 2011, Benetka et al. 2014). Variation in AGWB has been explained by variation in light interception, in biomass allocation, in leaf physiological factors related to RUE or in a combination of the aforementioned (Cannell et al. 1988, Green et al. 2001, Tharakan et al. 2008, suggesting inconclusive results on the relative importance of productivity determining factors in SRC. The quantification of genetic diversity and of genetic control contributes to future tree improvement and to yield maximization efforts towards sustainable bioenergy cultivation.In the present study, we analyzed the leaf area development, light interception and RUE of 12 poplar genotypes in a high-density SRC culture, before and after the first coppice of an experimental plantation. Assessment of LAI and woody biomass productivity was performed in a single versus a multi-stem culture, to analyze the effect of coppicing. We hypothesized significant genotypic, parentage and provenance variation in LAI, in leaf area duration (LAD), in RUE, in intercepted radiation (Iint) and AGWB. The objectives of this study were: (i) to determine the main differences between the first (R1) and the second rotation (R2) in the above mentioned parameters and in their relationships, i.e., before and after coppice,...

“…Several crossing strategies have been recently employed within breeding programs in order to increase yields, enhance disease and pests' resistance, improve growth form and resistance to the frost or dry stresses (Tognetti et al 2013). Genotypes that perform well according to the selection criteria (pest and disease resistances, estimation of yield and chemical composition) are chosen for future plantations (Benetka et al 2014).…”

“…However, some alternative sources for delivering biomass are recently considered as an opportunity, especially when regarding the production of biofuels. Woody energy crops, for instance, are grown solely for the production of renewable energy (Benetka et al 2014). Fast growing trees or shrub species (usually poplar, willow and eucalyptus) are cultivated on arable land with an intensive management including fertilizing, irrigation and weed/pest/disease control.…”

(4)Willow (Salix sp.) is one of the most common hardwood species suitable for short-rotation coppice. It can be converted to different products, including chemicals, fuels, fibers or furniture. It may also be used in agriculture and environmental engineering. Molecular composition of biomass and its physical properties highly influence effectiveness of its chemical, thermo-chemical or mechanical-chemical conversion. Therefore, it is challenging to provide biomass feedstock with optimized properties, best suited for further downstream conversion. The goal of this research was to establish a procedure for determination of the willow biomass optimal use cultivated in four different plantations in Poland. A special attention has been paid to the application of the near infrared spectroscopy for evaluation of biomass chemical composition and its physical properties. Near infrared spectroscopy (NIR) could be an alternative to standard analytical methods supporting the research and development of biomass production technologies. Partial least squares regression models for quantitative prediction of wood chemical components (lignin, cellulose, holocellulose, hemicellulose and extractives) and high heating values were developed. The residual prediction deviation (RPD) values confirm the applicability of chemometric models for screening in breeding programmes (for lignin, cellulose and extractives content) and for research in the case of high heating value. The analysis of NIR spectra highlighted several peculiarities in the chemical composition of the investigated willow clones. Finally, a knowledgebased expert system and a prototype automatic NIR system allowing the computation of a "suitability index" based on PLS models and dedicated to selection of optimal biomass conversion path, was developed.
