The main objective of this study was to compare the effects two densities (278 stems·ha ?1 with spacings 6 m × or 4.5 8 m, 400 5 3 m) and three poplar clones (NL95, NL895, NL797) on productivity carbon (C) sequestration ecosystems. results showed that planting density significantly affected biomass a single tree. mean tree clone NL95 higher in all than other clones, significant difference for s...

A cell wall determines the mechanical properties of a cell, serves as barrier against plant stresses, and allows division growth processes. The COBRA- Like (COBL) gene family encodes putative glycosylphosphatidylinositol (GPI)-anchored protein that controls cellulose deposition progression in plants by contributing to microfibril orientation wall. Despite being studied different species, there ...

Hybrid poplar (Populus spp.) is an important biomass crop being evaluated for cellulosic ethanol production. Predictions of poplar growth, rotation period, and soil carbon sequestration under various growing conditions, soils, and climates are critical for farmers and managers planning to establish short-rotation forestry (SRF) plantations. In this study, we used an ecoinformatics workflow, the...

The recent completion of a draft sequence of the poplar (Populus trichocarpa Torr. & Gray ex Brayshaw) genome has advanced forest tree genetics to an unprecedented level. A "parts list" for a forest tree has been produced, opening up new opportunities for dissecting the interworkings of tree growth and development. In the relatively near future we can anticipate additional reference genome sequ...

Comparative phylogenetic analyses of the R2R3-MYB transcription factor family revealed that five subgroups were preferentially found in woody species and were totally absent from Brassicaceae and monocots (Soler et al., 2015). Here, we analyzed one of these subgroups (WPS-I) for which no gene had been yet characterized. Most Eucalyptus members of WPS-I are preferentially expressed in the vascul...

The redbay ambrosia beetle, Xyleborus glabratus Eichhoff, is a non-native invasive pest and vector of the fungus that causes laurel wilt disease in certain trees of the family Lauraceae. This study assessed the relative attractiveness and suitability of cut bolts of several tree species to X. glabratus. In 2009, female X. glabratus were equally attracted to traps baited with swampbay (Persea pa...

Fourier transform infrared (FTIR) imaging offers the opportunity to analyse the chemical composition of wood spatially resolved. To illustrate the potential of FTIR imaging for wood analysis, the lignin distribution in cross sections of beech and poplar wood was analysed and the spatial resolution compared. Additionally, the ratio of guaiacyl/syringyl lignin in a poplar wood section was compute...

Aspen and poplar trees are important horticultural plants grown in Canada for aesthetic, commercial woodlot windbreak applications. Bronze leaf is a destructive disease Populus spp. caused by the fungal pathogen Apioplagiostoma populi Barr. This often difficult to isolate confirm from infected plant tissues has been mainly identified symptoms morphological characteristics of A. when fruiting bo...

Afforestation of former croplands has been proposed as a promising way to mitigate rising atmospheric CO2 concentration in view of the commitment to the Kyoto Protocol. Central to this C sequestration is the dynamics of soil organic C (SOC) storage and stability with the development of afforested plantations. Our previous study showed that SOC storage was not changed after afforestation except ...
