“…Most trials including M. × giganteus have been conducted in Europe where harvested yields have been reported as 10–30 t DW ha –1 ; the highest yields (up to 44 t DW ha –1 at the end of the growing season post-senescence) were reported from a trial in Illinois (Heaton et al , 2008). Comparisons between Miscanthus and other species such as bamboo (Hong et al , 2011), giant reed ( Arundo donax ; Angelini et al , 2009) and other C4 grasses (reviewed by van der Weijde et al ., 2013) consistently show Miscanthus to be among the most productive plant species for biomass production. In practice.…”

To accelerate domestication of Miscanthus, an important energy crop, 244 replicated genotypes, including two different species and their hybrids, were analysed for morphological traits and biomass yield over three growing seasons following an establishment phase of 2 years in the largest Miscanthus diversity trial described to date. Stem and leaf traits were selected that contributed both directly and indirectly to total harvested biomass yield, and there was variation in all traits measured. Morphological diversity within the population was correlated with dry matter yield (DMY) both as individual traits and in combination, in order to determine the respective contributions of the traits to biomass accumulation and to identify breeding targets for yield improvement. Predictive morphometric analysis was possible at year 3 within Miscanthus sinensis genotypes but not between M. sinensis, Miscanthus sacchariflorus, and interspecific hybrids. Yield is a complex trait, and no single simple trait explained more than 33% of DMY, which varied from 1 to 5297g among genotypes within this trial. Associating simple traits increased the power of the morphological data to predict yield to 60%. Trait variety, in combination, enabled multiple ideotypes, thereby increasing the potential diversity of the crop for multiple growth locations and end uses. Both triploids and interspecific hybrids produced the highest mature yields, indicating that there is significant heterosis to be exploited within Miscanthus that might be overlooked in early selection screens within years 1–3. The potential for optimizing biomass yield by selecting on the basis of morphology is discussed.

“…(Faruk et al, 2012). Both miscanthus and bamboo attracted attention for fuel production (Hong et al, 2011) but also for biocomposites reinforcement. Bourmaud and Pimbert (2008) tested, by nanoindentation, modulus and hardness of miscanthus fibre being 9.49 GPa and 0.34 GPa, respectively, showing it to have modulus between sisal (8.52 GPa) and hemp (12.14 GPa).…”

OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. b s t r a c tNatural fibres from miscanthus and bamboo were added to poly(lactic acid) by twin-screw extrusion. The influence of extruder screw speed and of total feeding rate was studied first on fibre morphology and then on mechanical and thermal properties of injected biocomposites. Increasing the screw speed from 100 to 300 rpm such as increasing the feeding rate in the same time up to 40 kg/h helped to preserve fibre length. Indeed, if shear rate was increased with higher screw speeds, residence time in the extruder and blend viscosity were reduced. However, such conditions doubled electrical energy spent by produced matter weight without significant effect on material properties. The comparison of four bamboo grades with various fibre sizes enlightened that fibre breakages were more consequent when longer fibres were added in the extruder. Longer fibres were beneficial for material mechanical properties by increasing flexural strength, while short fibres restrained material deformation under heat by promoting crystallinity and hindering more chain mobility.

“…O uso da biomassa de gramíneas de metabolismo C4 de alto potencial produtivo como Miscanthus e Panicum vem se destacando na produção de bioenergia (Schemer et al, 2008;Hong et al, 2011) e no Brasil o capim-elefante (Pennisetum purpureum Schum.) vem sendo avaliado para este fim, especialmente pela alta produtividade, qualidade da biomassa e pequena demanda de insumos para produção (Samson et al, 2005;Morais et al, 2011).…”

) e três idades de corte do capim (120, 150 e 180 dias após o brotamento). Avaliou-se, em cada idade de corte, a produção de matéria seca da parte aérea (folhas e colmos) e o acúmulo de N na planta. A produção de matéria seca do capim-elefante aumentou com a adição de N porém o efeito foi maior para as plantas cortadas com 180 dias de idade. Encontrou-se um incremento linear na acumulação de matéria seca (R 2 = 0,75**) e na acumulação de N (R 2 = 0,96**), permitindo uma produtividade de 34 t ha -1 de matéria seca, que implicou em uma extração de N de 471 kg ha -1 . A eficiência de utilização do N pela cultura variou com o aumento da idade da planta, o que significou maior quantidade de biomassa por unidade de N absorvido. O índice de eficiência mostra que o corte tardio pode favorecer a qualidade da biomassa para fins energéticos, por se tratar de um material mais fibroso. Palavras-chave: Pennisetum purpureum, biomassa, bioenergiaEffect of nitrogen fertilizer and cutting age on the dry matter production of elephant grass in Savana A B ST R A C T The objective of this study was to investigate the effect of the application of N fertilizer and the cutting age on the dry biomass production of elephant grass. The experiment was performed with the variety Paraíso and planted in a Ferralsol in 2008 in the district of Gurupi (State of Tocantins). Four different rates of urea application were tested (0, 50, 100 and 150 kg ha -1 ) and harvests were made at 120, 150 or 180 days after germination (DAG) of the setts. The dry matter and total N accumulation were evaluated. Dry matter production increased with dose of N, the greatest effect being observed at 180 DAG. There was a linear increase in dry matter (R 2 = 0.75**) and N accumulation (R 2 = 0.96**) permitting a productivity of 34 t ha -1 of dry matter and an accumulation of 471 kg N ha -1. The N utilization efficiency (biomass production per unit of applied N) increased with plant age. The higher efficiency of N use favored the quality of biomass production for energy production owing to the higher fibre content.
