FISCHER, M., TRNKA, M., KUČERA, J., FAJMAN, M., ŽALUD Z.: Biomass productivity and water use relation in short rotation poplar coppice (Populus nigra x P. maximowiczii) in the conditions of Czech MoravianHighlands. Acta univ. agric. et silvic. Mendel. Brun., 2011, LIX, No. 6, pp. 141-152 The plantations of short rotation coppice (SRC) usually based on poplar or willow species are promising source of biomass for energy use. To contribute to decision-making process where to establish the plantations we evaluated the water consumption and its relation to biomass yields of poplar hybrid clone J-105 (Populus nigra x P. maximowiczii) in representative conditions for Czech-Moravian Highlands. Water availability is usually considered as one of the main constraints of profi table SRC culture and therefore we focused on analyzing of the linkage between the aboveground biomass increments and the total stand actual evapotranspiration (ET a ) and on water use effi ciency of production (WUE P ). During the seasons 2008 and 2009 the total stand ET a measured by Bowen ratio energy balance system constructed above poplar canopy and the stem diameter increments of randomly chosen sample trees were examined. The stem diameters were subsequently converted to total aboveground biomass (AB) by allometric equation obtained by destructive analysis at the beginning of 2010. The biomass volume and its increment of particular trees were subsequently converted to the whole canopy growth and correlated with the ET a values. Our results revealed that there was a statistically signifi cant relation between water lost and biomass growth with coeffi cients of determination r 2 0.96 and 0.51 in 2008 and 2009 respectively. By using multiple linear regression analysis additionally accounting for eff ect of precipitation events and thermal time (sums of eff ective temperatures above +5 °C) the AB growth was explained from 98 and 87% in 2008 and 2009, respectively. Therefore for further analysis the multiple linear regression model was applied. The dynamic of seasonal WUE P (expressed as gram of AB dry matter per thousand grams of water) reached up to 6.2 and 6.8 g kg −1 with means 3.13 and 3.54 g kg −1 in both executed years respectively. These values are situated in higher range comparing to the other broadleaved tree species of temperate climate zone and suggest that economically profi table plantation (defi ned by yield at least in the range of 10-12 Mg ha −1 year −1 of dry matter content) will consume more than 450-500 mm per growing season and thus will demand a locality with higher and adequately temporally distributed amount of precipitation especially in rain fed areas such as the discussed Czech-Moravian Highlands.short rotation coppice, biomass increment, water consumption, water use effi ciencyThe term short rotation coppice (SRC) is generally used for any high-yielding woody species managed in a coppice system usually grown especially for energy use on arable land.

There is increasing competition for raw materials between particleboard production, thermal energy recovery, and pulp-and papermaking. According to different scenarios, the consumption of lignocellulosic raw materials is increasing, which means that the competition is increasing. The primary production of lignocellulosic raw material in some regions may therefore reach the limit of sustainability; i.e., the lignocellulosic raw material must be used more efficiently to reduce the risk of a shortage. The physical and chemical properties of the lignocellulosic raw material of selected species have therefore been surveyed, and the raw material properties that are important for each of the three competitors have been defined. The aim of the study is to characterise the lignocellulosic raw materials according to the three competing users and to show whether they are high or low in competition. As methods, a relative ranking of the species regarding their raw material properties and regarding the requirements of the competitors as well as cluster analysis were chosen. The results show that the most favourable raw materials are from coniferous species, while monocotyledon species show an opposite trend.

“…Pentru o densitate și mai mare de până la 10000 exemplare per ha, testată într-un experiment din Cehia, reușește să obțină după 6 sezoane de creștere o înălțime mai mare decât restul clonelor testate (ajunge la cca. 11,0 m) (Trnka et al 2008). Densitatea mare de plantare nu implică neapărat creșteri mai mari în înălțime, astfel încât pentru densitatea utilizată în studiul nostru (2667 exemplare per ha) s-au obținut valori apropiate ale înălțimilor cu cele obținute în studii unde s-au utilizat densități mai ridicate de plantare.…”

“…Într-o altă ordine de idei, într-un studiu elaborat în Cehia, mărirea ciclului de producție la 6 ani de vegetație, nu favorizează obținerea unor randamente superioare pentru aceeași densitate de plantare (10000 exemplare per ha). În aceste condiții se obțin randamente tot mai mici de biomasă, care variază de la 2,6 la 13,9 t/ha/an, iar clona Max 4 prezintă creșterile cele mai importante (Trnka et al 2008). Încât, pentru densități mari de plantare, se recomandă o exploatare după perioade scurte pentru obținerea unor randamente superioare.…”

. Poplar clones productivity managed for biomass production in North-Eastern Romania. Bucov. For. 16(1): 73-85.Abstract. 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.
