$a Hustota a sypná hmotnosť energetickej štiepky z dendromasy plantážnicky pestovaných porastov rýchlorastúcich drevín $d Density and bulk density of green wood chips from dendromass of short rotation coppice grown on plantations $f Adrián Banski, Ladislav Dzurenda 215 $c Graf., obr., tab. 320 $a Lit. 330 $a This article presents the results of works which determine density of chips, juvenile wood and juvenile bark in a dry condition on the basis of dendromass of fast growing wood species grown on plantations – willow, poplar and acacia, aged 5–12 years. By the means of the experimental works it has been found out that the juvenile wood density of Salix viminalis is ρ0D = 486.6 kg×m−3, Populus ρ0D = 415.6 kg×m−3 and Robinia pseudoacacia ρ0D = 678.1 kg m-3. The average values of juvenile bark density of analysed wood speciec are Salix viminalis ρ0K = 625.1 kg×m−3, Populus ρ0K = 575.7 kg×m−3 and Robinia pseudoacacia ρ0K = 762.9 kg×m−3. The density of dry willow bark is by 22.1 %, poplar bark by 27.8 % and locust bark by 11.1 % higher than density of dry juvenile wood. Higher bark density than density of wood is reflected in the increase in biomass density chips. The work also contains data reflecting bulk density of chips from analysed wood species made on a chopping machine JUNKKARI HL 10, at relative humidity of willows and poplars at harvest wr = 52 % and of acacia wr = 37 %. Bulk density of willow dendromass has a value ρprms-w = 356.1 kg m- 3, poplar ρprms-w = 301.2 kg×m−3 and acacia ρprms-w = 481.5 kg×m−3. The above data considering the weight of 1 m3 chips are an important indicator for designers who design warehouse space for storage of chips, as well as for carriers who transport chips from plantations to warehouses. 330 $a V danom príspevku sú prezentované výsledky experimentálnych prác stanovujúce hustotu suchej dendromasy - energetickej štiepky a jednotlivých jej komponentov: juvenilného dreva a juvenilnej kôry z plantažnicky pestovaných porastov klonov: RAPP, ORM, Inger, Sven, Tordis, dreviny Salix viminalis, klonov: Max 4, Max 5,Oxford, AF 2, Monviso, dreviny Populus, klonov: Ambigua, Debrecenyi 2, Gori, Nyirsegi, Rozaszin, dreviny Robinia pseudoacacia a sypnú hmotnosť štiepky uvedených klonov s vlhkosťou v čase zberu z plantáže. 463 -1
