“…For example, selection for hybrid poplar feedstocks with high densities and strengths may contribute to elevated pulp yields, while medium densities are more appropriate for oriented strand board (OSB) and plywood [8,25,26]. Likewise, high density wood is a requirement for thermochemical conversion and direct combustion technologies, whereby specific gravity and process efficiency are positively correlated [19,20]. Similarly, greater specific gravities increase transportation efficiencies because more biomass per truckload is delivered to processing facilities [22].…”

“…Given the broad genetic variability within the genus Populus [16][17][18], certain genotypes exhibit wood property traits that are ideal for many of these uses, despite the fact that selection for one trait may reduce the quality and/or contribution of another. Physical traits that contribute to feedstock quality and, thus, the economic viability of growing SRWCs include but are not limited to: moisture content, bark:wood ratio, heating value, and specific gravity [19,20].…”

Specific gravity is an important consideration for traditional uses of hybrid poplars for pulp and solid wood products, as well as for biofuels and bioenergy production. While specific gravity has been shown to be under strong genetic control and subject to within-tree variability, the role of genotype × environment interactions is poorly understood. Most specific gravity reports are for a limited number of locations, resulting in a lack of information about the interactions between clones and sites over a wide range of climate and soil conditions. The objective of the current study was to characterize the effects of bole position, site, clone, and site × clone interactions for twelve hybrid poplar genotypes grown in Iowa, Minnesota, Wisconsin, and Michigan, USA. Observed specific gravities ranged from 0.267 to 0.495 (mean = 0.352 ± 0.001 for 612 samples taken from 204 trees), with bole position and site × clone interactions having significant effects on specific gravity. Further investigation of the site × clone interactions indicated that environmental conditions related to water stress were key predictors of specific gravity. These data are OPEN ACCESSForests 2013, 4 252 important for informing genotypic selection and silvicultural management decisions associated with growing hybrid poplars.

“…The main species under this cultivation regime in temperate climates are poplar (Populus spp) [12], willow (Salix spp) [13] and eucalyptus (Eucalyptus spp.) [14], and to a lesser extent, black locust (Robinia pseudoacacia L.) [15] and alder (Alnus spp.)…”

“…One avenue to circumvent this problem and accelerate decontamination is the use of fast-growing trees, such as willows and poplars [21][22][23][24][25]. Through their extensive and widespread root systems, which can measure up to several meters long, willows improve the structure and texture of soil [26] and reduce erosion [27]. Furthermore, willows have demonstrated an ability to adapt to varying soil textures (sandy to clay) and humidity, due to their high transpiration rate and their roots ability to tolerate seasonal floods.…”

Root Exudation: The Ecological Driver of Hydrocarbon Rhizoremediation

2016

Rhizoremediation is a bioremediation technique whereby microbial degradation of organic contaminants occurs in the rhizosphere. It is considered to be an effective and affordable "green technology" for remediating soils contaminated with petroleum hydrocarbons. Root exudation of a wide variety of compounds (organic, amino and fatty acids, carbohydrates, vitamins, nucleotides, phenolic compounds, polysaccharides and proteins) provide better nutrient uptake for the rhizosphere microbiome. It is thought to be one of the predominant drivers of microbial communities in the rhizosphere and is therefore a potential key factor behind enhanced hydrocarbon biodegradation. Many of the genes responsible for bacterial adaptation in contaminated soil and the plant rhizosphere are carried by conjugative plasmids and transferred among bacteria. Because root exudates can stimulate gene transfer, conjugation in the rhizosphere is higher than in bulk soil. A better understanding of these phenomena could thus inform the development of techniques to manipulate the rhizosphere microbiome in ways that improve hydrocarbon bioremediation.
