“…Giant miscanthus biomass production has been highest in Illinois (>30 Mg ha −1 year −1 ), with lower yield potential in the South and Southeastern regions (2.5 to 17 Mg ha −1 year −1 ) [19][20][21]. Giant miscanthus is established by planting rhizomes 5-10 cm deep into a prepared seed bed at 14,000 to 17,000 rhizomes ha −1 in 76-cm rows [22].…”

“…Both napier grass and energy cane produce more stalks per unit area than sugarcane, contributing to higher biomass in subtropical regions [27,29]. Results from Georgia [30,31] and Florida [19] field trials show that napier grass and energy cane yields were significantly higher than switchgrass, giant miscanthus, and giant reed (Arundo donax L). However, moisture and ash content of napier grass and energy cane could pose a problem for conversion facilities [31].…”

Dedicated Energy Crops and Crop Residues for Bioenergy Feedstocks in the Central and Eastern USA

Dedicated energy crops and crop residues will meet herbaceous feedstock demands for the new bioeconomy in the Central and Eastern USA. Perennial warm-season grasses and corn stover are well-suited to the eastern half of the USA and provide opportunities for expanding agricultural operations in the region. A suite of warm-season grasses and associated management practices have been developed by researchers from the Agricultural Research Service of the US Department of Agriculture (USDA) and collaborators associated with USDA Regional Biomass Research Centers. Second generation biofuel feedstocks provide an opportunity to increase the production of transportation fuels from recently fixed plant carbon rather than from fossil fuels. Although there is no "one-size-fitsall" bioenergy feedstock, crop residues like corn (Zea mays L.) stover are the most readily available bioenergy feedstocks. However, on marginally productive cropland, perennial grasses provide a feedstock supply while enhancing ecosystem services. Twenty-five years of research has demonstrated that perennial grasses like switchgrass (Panicum virgatum L.) are profitable and environmentally sustainable on marginally productive cropland in the western Corn Belt and Southeastern USA.

“…However, in the first ratoon cycle, only VX12-1022 (63 Mg ha −1 ) had greater aboveground dry biomass production than sugarcane (53 Mg ha −1 ) (Fig. For comparison purposes, in the United States, energy cane dry biomass production ranged from 8 to 53 Mg ha −1 , depending on location, genotype, irrigation, and rate of fertilization (Bischoff et al, 2008;Knoll et al, 2012;Fedenko et al, 2013). The high level of dry biomass production by both energy cane and sugarcane was probably due to the fertilization and irrigation applied during early crop development in both crop cycles (Fig.…”

Energy cane (Saccharum spp.) is an alternative for biomass production to meet demands for high yield and fiber content feedstock for bioenergy production. However, there is limited research data and information available for this crop that was recently introduced in Brazil. The focus of this study was to evaluate the biomass production and mineral composition of energy cane genotypes to understand their productivity and define nutrient management practices according to nutrient removal. The experiment was conducted in northeastern Brazil during plant cane and first ratoon crop cycles and evaluated six energy cane and one sugarcane (cultivar most grown in the region) genotype. Depending on genotype and crop cycle, energy cane dry biomass production ranged from 43 to 63 Mg ha−1 and was greater than that of sugarcane, ranging from 25 to 51 Mg ha−1. Energy cane allocated a greater amount of dry biomass in dry leaves and tops than sugarcane. Overall, 1 Mg of fresh energy cane required 1.5 kg of N, 0.32 kg of P, 5.1 kg of K, 0.6 kg of Mg, 0.5 kg of S, 5.7 g of B, 1.4 g of Cu, 6.3 g of Mn, and 4.7 g of Zn. Macronutrient removal by some energy cane genotypes was higher than that by sugarcane due to greater biomass production. Energy cane has the potential for greater dry biomass production than sugarcane, but it also removes a larger amount of nutrients. The recommendation of an amount of nutrients needed for energy cane production is a key issue for the establishment of this crop as a raw material for bioenergy production in Brazil.

“…The growing demand for petroleum products, the limited reserves of fossil fuels and the global warming attributed to the use of this energy source indicate the urgent need to find alternative sources of renewable energy [1]. Biomass used for energy is mainly derived from the processing of agricultural and forest products, waste from holdings, the remains of forestry, and crop residues as well as from crops planted and exploited for the sole purpose of obtaining biomass [2]. These latter are called energy crops and include forest and agricultural crops.…”

Overexpression of a pine Dof transcription factor in hybrid poplars: A comparative study in trees growing under controlled and natural conditions

et al. 2017

In this work, the role of the pine transcriptional regulator Dof 5 in carbon and nitrogen metabolism has been examined in poplar trees. The overexpression of the gene and potential effects on growth and biomass production were compared between trees growing in a growth chamber under controlled conditions and trees growing in a field trial during two growth seasons. Ten-week-old transgenic poplars exhibited higher growth than untransformed controls and exhibited enhanced capacity for inorganic nitrogen uptake in the form of nitrate. Furthermore, the transgenic trees accumulated significantly more carbohydrates such as glucose, fructose, sucrose and starch. Lignin content increased in the basal part of the stem likely due to the thicker stem of the transformed plants. The enhanced levels of lignin were correlated with higher expression of the PAL1 and GS1.3 genes, which encode key enzymes involved in the phenylalanine deamination required for lignin biosynthesis. However, the results in the field trial experiment diverged from those observed in the chamber system. The lines overexpressing PpDof5 showed attenuated growth during the two growing seasons and no modification of carbon or nitrogen metabolism. These results were not associated with a decrease in the expression of the transgene, but they can be ascribed to the nitrogen available in the field soil compared to that available for growth under controlled conditions. This work highlights the paramount importance of testing transgenic lines in field trials.
