Understanding the complex relationships among climate, tree growth, and water availability is key for predicting the performance of environmentally and economically salient tree species like Pinus ban...
The response of vegetation to climate change is of special interest in regions where rapid warming is coupled with moisture deficit. This raises the question of the limits in plants’ acclimation abili...
The study deals with differences in the growth of 2-year mix of poplar clones MAX 4, MAX 5 in the first rotation period at a site with the average moisture regime and at a neighbouring site affected b...
As the tree age increases, the formation of heartwood takes place in the central part of the tree. Since there is a large difference in the moisture content between sapwood and heartwood in conifers, ...
Changbai Mountain Natural Reserve (1,985 km2 and 2,734 m a.s.l.) of Northeast China is a typical ecosystem representing the temperate biosphere. The vegetation is vertically divided into 4 dominant zo...
Beechnuts from three Fagus sylvatica lots were dried at 20°C to 5–6% or 8–9% (fresh weight basis) moisture content and stored at –7°C or –22°C for 3.5 or 4.5 years in sealed polyethylene bags containi...
The paper describes the regime and dynamics of the soil moisture content of sandy soils in Záhorská lowland during different growing seasons. Research plots are situated near Kamenny mlyn, appr...
Floodplain forest response to changed soil moisture regime and nutrient availability due to river regulation was studied using remote sensing (ETM) data. Images of May and October 2001 were used to pr...
The condensation of transpiration and advective water fallows (further—the phenomenon) under the close grass cenosis can be compared to the quantity of precipitation. The phenomenon depends on physica...
Oil palm seedlings were subjected to water stress by suspension of watering. At 9 days of stress, water potentials had decreased to -2.4 Mpa. Moisture stress under these conditions provoked about 20% ...
Distribution of the moisture content across stem wood at breast height in Acacia mangium, A. auriculiformis,and hybrid Acacia trees grown in 3 Asian countries was evaluated. Moisture contents of the s...
Model parameterization was performed for estimation of the fuel moisture in adjacent plots with different tree species aiming at the mapping of forest fire hazard. One plot was covered with only decid...
The effects of wood species, thickness and cross-section factors on wood moisture content under centrally heated indoor conditions in Trabzon. Factors of thickness, cross-section and wood species were...
The effect of moisture content and wood density on the preservative uptake (on the basis of the percentage of void volume filled (VVF%)) of Caucasian fir (Abies nordmanniana (Link.) Spach.) was studie...
Heat treatment is often used for improve the dimensional stability of wood. In this study, effect of heat treatment on equilibrium moisture content (EMC) of oak (Quercus petraea Lieb.), chestnut (Cast...
