“…These data indicate that nutrient cycling from the shoots to the below-ground tissues directly impacts meristems on the crowns and rhizomes, and potentially winter-survival of the plant. In a large-scale analysis of different grasses across the southern half of the USA [31] yield components were dependent on the interactions between the environment and genotype. As an example, colder winter temperatures favored upland switchgrasses as compared to the lowland cultivar Alamo.…”

Senescence, dormancy and tillering in perennial C4 grasses

a b s t r a c tPerennial, temperate, C 4 grasses, such as switchgrass and miscanthus have been tabbed as sources of herbaceous biomass for the production of green fuels and chemicals based on a number of positive agronomic traits. Although there is important literature on the management of these species for biomass production on marginal lands, numerous aspects of their biology are as yet unexplored at the molecular level. Perenniality, a key agronomic trait, is a function of plant dormancy and winter survival of the belowground parts of the plants. These include the crowns, rhizomes and meristems that will produce tillers. Maintaining meristem viability is critical for the continued survival of the plants. Plant tillers emerge from the dormant crown and rhizome meristems at the start of the growing period in the spring, progress through a phase of vegetative growth, followed by flowering and eventually undergo senescence. There is nutrient mobilization from the aerial portions of the plant to the crowns and rhizomes during tiller senescence. Signals arising from the shoots and from the environment can be expected to be integrated as the plants enter into dormancy. Plant senescence and dormancy have been well studied in several dicot species and offer a potential framework to understand these processes in temperate C 4 perennial grasses. The availability of latitudinally adapted populations for switchgrass presents an opportunity to dissect molecular mechanisms that can impact senescence, dormancy and winter survival. Given the large increase in genomic and other resources for switchgrass, it is anticipated that projected molecular studies with switchgrass will have a broader impact on related species.

“…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].…”

“…ALMANAC was used to predict yield (3.8 to 20.9 Mg ha −1 ) and WUE of four switchgrass ecotypes at five sites across the Midwest [113,114]. Modeled WUE values (3 to 6 mg g −1 ) tended to match published empirically measured values, with lowland types having the greatest WUE [21,113]. As changes in climate increases the possibility of drought stress, ecotypes or cultivars with high WUE will be needed to maintain higher yields.…”

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.

“…In the first experiment, yields of M. x giganteus and four switchgrass ecotypes were collected over multiple years at six locations in SGP regions in Texas, Louisiana, Oklahoma, and Missouri. This study expands upon previous research [40] which evaluated switchgrass productivity at multiple locations in the SGP by adding three additional years of yield data and a new site. The purpose of this study was to evaluate the most productive perennial plant variety in each location.…”

Adaptation of C4 Bioenergy Crop Species to Various Environments within the Southern Great Plains of USA

et al. 2017

Abstract:As highly productive perennial grasses are evaluated as bioenergy feedstocks, a major consideration is biomass yield stability. Two experiments were conducted to examine some aspects of yield stability for two biofuel species: switchgrass (Panicum vigratum L.) and Miscanthus x giganteus (Mxg). Biomass yields of these species were evaluated under various environmental conditions across the Southern Great Plains (SGP), including some sites with low soil fertility. In the first experiment, measured yields of four switchgrass ecotypes and Mxg varied among locations. Overall, plants showed optimal growth performance in study sites close to their geographical origins. Lowland switchgrass ecotypes and Mxg yields simulated by the ALMANAC model showed reasonable agreement with the measured yields across all study locations, while the simulated yields of upland switchgrass ecotypes were overestimated in northern locations. In the second experiment, examination of different N fertilizer rates revealed switchgrass yield increases over the range of 0, 80, or 160 kg N ha −1 year −1 , while Mxg only showed yield increases between the low and medium N rates. This provides useful insights to crop management of two biofuel species and to enhance the predictive accuracy of process-based models, which are critical for developing bioenergy market systems in the SGP.
