Dilute acid (DA) and Sulfite Pretreatment to Overcome Recalcitrance of Lignocelluloses (SPORL) pretreatments were directly applied to wood chips of four poplar wood samples of different genotypes (hereafter referred to as poplars; Populus tremuloides Michx. ‘native aspen collection’; Populus deltoides Bartr. ex Marsh Populus nigra L. ‘NE222’ and ‘DN5’; P. nigra Populus maximowiczii A. Henry ‘NM...

Morphological differences among Korean Allium subgenus Rhizirideum sect. Sacculiferum and some related species are minor, making species delimitation difficult. Inter-simple sequence repeat (ISSR) was employed to assess genetic diversity and relationships. Thirty-four accessions, representing six taxa of A. thunbergii, A. sacculiferum, A. deltoides-fistulosum, A. cyaneum var. cyaneum, A. cyaneu...

The goal of this study was to investigate the effect glass fiber reinforced polymer (GFRP) on joints made laminated veneer lumber (LVL), through experimental data and evaluation by ANSYS finite element (FE) software. In order fabricate LVL, from poplar (Populus deltoides Bartr. ex Marsh) with 2.5 mm thickness PVA adhesive were used. T-shape out LVL two wooden dowels incorporated as well. Then G...

*Correspondence: J. Y. Zhu, Forest Products Laboratory, 1 Gifford Pinchot Dr., Madison, WI, USA e-mail: [email protected] Poplar NE222 (Populus deltoides Bartr. ex Marsh×P. nigra L.) wood chips were pretreated in a 390 L pilot-scale rotating wood-pulping digester using a dilute sulfite solution of approximately pH 1.8 at 160°C for 40 min for bioconversion to ethanol and lignosulfonate (LS). An est...

Despite its economic importance as a bioenergy crop and key role in riparian ecosystems, little is known about genetic diversity and adaptation of the eastern cottonwood (Populus deltoides). Here, we report the first population genomics study for this species, conducted on a sample of 425 unrelated individuals collected in 13 states of the southeastern United States. The trees were genotyped by...
