Pretreatment of hybrid poplar by aqueous ammonia

Biotechnology Progress, 2009
AbstractEnzymatic hydrolysis of hybrid poplar treated by ammonia recycle percolation (ARP) was studied applying cellulase enzyme supplemented with additional xylanase or pectinase. The effect of xylanase addition was much more significant than pectinase addition.

Phytoremediation of MTBE with Hybrid Poplar Trees

International Journal of Phytoremediation, 2004
This research investigates the fate and transport of methyl tert-butyl ether (MTBE) in phytoremediation, particularly the uptake and volatilization of MTBE in lab-scale hydroponic systems. The research reveals that MTBE was taken up by hybrid poplar cuttings and volatilized to the atmosphere.

Proteomic analysis of hybrid poplar xylem sap

Phytochemistry, 2009
Xylem sap collected from Populus trichocarpaxPopulus deltoides using root pressure was estimated to contain more than 100 proteins. Ninety-seven of these proteins were identified using liquid chromatography-tandem mass spectrometry (LC-MS/MS). These proteins were classified into 10 functional categories including metabolism, signaling, stress response ...

Phosphorus-induced micronutrient disorders in hybrid poplar

Plant and Soil, 1990
The prevention and correction of P-induced nutrient disorders in hybrid poplar ( P 'Ř x euramericana ) were examined in field trials at an Ontario forest tree nursery. The disorders were prevented and alleviated by Zn and Cu fertilization, confirming preliminary diagnoses that the growth inhibition was attributed more to induced Zn and Cu deficiencies ...

MicroRNA257 promotes secondary growth in hybrid poplar

Plant Physiology and Biochemistry
Populus, a significant fast-growing tree species with global afforestation and energy potential, holds considerable economic value. The abundant production of secondary xylem by trees, which serves as a vital resource for industrial purposes and human sustenance, necessitates the orchestration of various regulatory mechanisms, encompassing ...

Natural root grafting in hybrid poplar clones

Trees, 2020
Root grafting occurs in 15-year-old hybrid poplar clones; and tree proximity, tree and root sizes are key factors enhancing its frequency. Root grafting in trees is a well-recognized phenomenon allowing nutrient and photosynthate redistribution between connected trees.

Fractionating Pentosans and Hexosans in Hybrid Poplar

Industrial & Engineering Chemistry Research, 2011
In this paper, a study on the fractionation of pentosans and hexosans from poplar chips was performed using a circulation reactor. The study’s methodology created kinetic models of both pentosan and hexosan hydrolysis/degradation to predict the fractionation yield of both substances. The conditions were varied to include a temperature range of 140–170 °

Fractional Catalytic Pyrolysis of Hybrid Poplar Wood

Industrial & Engineering Chemistry Research, 2010
Fractional catalytic pyrolysis is a selective in situ conversion of biopolymers into desired products. Fractional catalytic pyrolysis was used to convert the lignin fraction of hybrid poplar wood into high yields of cresols and phenols while the carbohydrate fraction was selectively converted into gaseous products.
