“…Although actual phytoremediation effectiveness was not evaluated in these cycles, a longer (15-mo) in situ study (cycle 4) was conducted that involved evaluating approximately 20 traits. The tissue concentration of contaminants in the roots, stems, and leaves, along with soil and leachate concentrations, were tested (Zalesny et al, 2007a;2007b;2007c). Ultimately, superior clones will be selected for the resource manager as early as 21 mo from the planting of selection cycle 1.…”

Information about the response of poplar (Populus spp.) genotypes to landfill leachate irrigation is needed, along with efficient methods for choosing genotypes based on leachate composition. Poplar clones were irrigated during three cycles of phyto-recurrent selection to test whether genotypes responded differently to leachate and water, and to test whether the methodology had merit as a tool for plant selection during remediation. Fifteen below-and above-ground traits were evaluated. Twenty-five clones were tested in cycle 1, while the best 12 genotypes were evaluated in cycles 2 and 3. Eight clones were selected and subsequently tested in an in situ landfill study (cycle 4). Results from cycles 1, 2, and 3 are presented here. Overall, clones responded differently to irrigation treatments, with certain genotypes exhibiting better below-and above-ground growth with water than leachate. However, growth was greater with leachate irrigation for some clones. In addition, differences between treatments within clones decreased with days after planting (DAP). There were no treatment differences for number of leaves, height, and root length at the end of cycle 2 (45 DAP) or cycle 3 (30 DAP). These results detail the extensive variation in clonal responses to leachate irrigation, along with the need and efficacy of using phyto-recurrent selection to choose superior genotypes.

“…For example, certain Populus hybrids are used as components of agronomic intercropping systems to stabilize soils and provide critical wildlife habitat [3,4]. Hybrid poplars are also used extensively in phytotechnologies to clean sites contaminated with inorganic and organic constituents [5,6]. Moreover, given their greater productivity levels relative to most other temperate-grown, deciduous trees [7], hybrid poplars are ideal for providing biomass for multiple end uses (i.e., the provisioning services).…”

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 variation in performance points out (Zalesny et al 2009) found significant genotype 9 environment interactions. Likewise, there were clonal differences in response to irrigation with landfill leachate containing high levels of N, P, and K (Zalesny et al , 2008. These findings indicate that the ranking of clonal performance would likely have been different at different locations or under different nutrient availabilities.…”

“…Among the tree components, foliage has the highest and stem wood tends to have the lowest N and P concentrations (Van Lear et al 1984;Singh 1998;Ponette et al 2001;Rockwood et al 2004;Swamy et al 2006;Cobb et al 2008;Zalesny et al 2008). This was true in our study, except for stem P which was higher than P concentration in the bark and branch.…”

Evaluating performance of short-rotation woody crops for bioremediation purposes

Decommissioned animal waste lagoons contain large quantities of nutrients including nitrogen (N) and phosphorus (P) and can cause pollution of nearby water resources. Using short-rotation woody crops (SRWCs) for nutrient uptake and biomass production might be an inexpensive and eco-friendly method for the stabilization of decommissioned lagoons. We evaluated the annual growth performance and nutrient uptake by sycamore (Platanus occidentalis) for five growing seasons and 25 different clones of eastern cottonwood (Populus deltoides) for four growing seasons in a soil backfilled, dewatered swine lagoon in north-central Oklahoma. Growth performance and nutrient uptake of cottonwood was higher than the sycamore in our study. At the end of the study, 5-year old sycamore reached an average height of 5.84 m [standard error (SE) = 0.39] and had an average diameter at breast height (dbh) of 5.91 cm (SE = 0.20), compared to 4-year old cottonwood height of 7.58 m (SE = 0.15) and dbh of 8.22 cm (SE = 0.34), respectively. Sycamore produced almost 30 Mg ha -1 of total biomass, whereas cottonwood produced 53 Mg ha -1 by the end of the study. Total N and P uptake by sycamore was 327 (SE = 24) and 51 (SE = 4) kg ha -1 respectively, whereas cottonwood N and P uptake was 699 (SE = 41) and 99 (SE = 6) kg ha -1 , respectively, by the end of the study. We conclude that SRWCs can use substantial amounts of nutrients from the decommissioned lagoons while producing wood and fiber products.
