“…Then, some of them can be harvested in two or even three cuts during one growing season instead of waiting for one harvest after they stop growing. Besides, the species Helianthus tuberosus grown as an energy or industrial crop can be harvested for both the aerial parts and tubers (Curt et al, 2006;Kondor and Dallos, 2010). Different species of perennial crops, beside providing biomass for industrial aims or energy generation, play an important role in the reclamation of contaminated land.…”

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

“…Differences in specific adaptations of clones imply significant genotype (G) × environment (E) interactions. Previous researches demonstrated that the quality and yield of ethanol produced from Jerusalem artichoke is dependent on the tuber yield, tuber quality and fermentation process (Judd, 2003;Szambelan et al, 2004;Curt et al, 2006;Negro et al, 2006;Stolzenburg, 2006). Total soluble sugar content of tuber in all genotypes varied between 30.7 and 68.0% in this study.…”

The study was aimed to evaluate the potential of existing genotypes of Jerusalem artichoke (Helianthus tuberosus L.) as biomass feedstock for ethanol production. We investigated the biomass productivity and chemical composition of twenty-six Jerusalem artichoke clones grown in a semi-arid region of China. Jerusalem artichoke was demonstrated to be a sustainable feedstock for bioethanol production. All structural and non-structural carbohydrates in whole plant of Jerusalem artichoke could be 5000 L/ha. The above-ground biomass of Jerusalem artichoke could be a promising feedstock for cellulosic ethanol. The ethanol potential yield from cellulose and hemicellulose in aboveground biomass were 1821 to 5930 L/ha, contributing 29.8-66.4% of the total ethanol yield, which could be as high as that from switchgrass and sweet sorghum stem. Large variation among the investigated genotypes for carbohydrates makes it possible to select suitable clones to be used in bioethanol production in semiarid regions. Clones HB-3, HEN-3, IM-1, SC-1, SHX-3, SX-2 and ZJ-2 yielded tuber total soluble sugar higher than 4.0 t/ha. Clones BJ-4, HUB-2, HUN-2, QH-1, SD-2 and SHH-1 produced more than 5.0 t/ha cellulose and hemicellulose in above-ground biomass. Clones BJ-4 and HUB-2 have the highest ethanol potential based on structural carbohydrates. These clones were promising material if used as biofuel feedstock in this growth condition.

“…The tubers are rich in inulin (a fructose polymer), which can be used to obtain a syrup for use both in the foodstuffs industry and in the production of ethanol. It was demonstrated (Curt et al, 2006) that, towards the end of the season, the potential for bioethanol production of the stems of clones is 38% of that of the tubers.…”
