Background: Traditional methods used to monitor the aboveground biomass (AGB) and belowground biomass (BGB) of slash pine (Pinus elliottii) rely on on-ground measurements, which are time- and cost-con...
The incidence of the summer (late-seasonal) growth of shoots was monitored following the planting of Scots pine from different provenances of the Czech Republic and different planting regimes in an ex...
To obtain the pine trees with high resistance to the pine wilt from susceptible species, the criteria for selective breeding should be made based on the inhibition factors of symptom development. Migr...
We present a weighted, individual-tree relative density approach whose reference conditions have the same distribution of crown areas and species as a subject stand. An initial evaluation of the me...
Certain types of chemicals can affect the gravitropism of roots. In a laboratory study, intact loblolly pine (Pinus taeda L.) radicles (emerged from H2O2-treated seeds) exhibited positive gravitro...
This study compares pine natural regeneration density and height growth in small harvested openings (0.01–0.07 ha) within two biogeoclimatic subzones (Sub-Boreal Pine–Spruce [SBPS] xc and Montane Spru...
Copper-treated Styrofoam containers and containers with side slits have been designed to modify the root systems of seedlings grown in hardwall containers. By chemical- or air-pruning major lateral ro...
This study was carried out to determine the shear and bending strength of different end-to-end grain joints, which were glued with PVAc (polyvinyl acetate). For this reason, specimens, prepared from s...
Bursaphelenchus mucronatus, a species closely related to the pinewood nematode (Bursaphelenchus xylophilus, a quarantine pest), was isolated from several wilted pine trees in different provinces of Tu...
Monochamus galloprovincialis (Olivier) is the vector of the pinewood nematode, Bursaphelenchus xylophilus (Steiner and Buhrer) Nickle, in Europe and Asia. Reproduction is probably the most important e...
