• Risk assessment of ozone effects on forests is gradually moving from concentration-based exposure metrics to a more complicated approach that requires modelling of ozone fluxes to trees.
• This study reviews the status of the DO3SE stomatal flux model employed within the Convention on...
• This review considers potential effects of atmospheric change and climate warming within the timberline ecotone of the Central European Alps. After focusing on the impacts of ozone (O3) and rising atmospheric CO2 concentration, effects of climate warming on the carbon and water balance of...
• The quality of monitoring is defined by its ability to provide data that (i) allow estimates of the status of the target resource with defined precision level, (ii) permit change detection with defined power, and (iii) are comparable through space and time. To achieve these requirements a...
• Each annual ring in pines consists of earlywood and latewood with considerable difference in density and width. To get a better determination of the genetic regulation of total wood density in Scots pine (Pinus sylvestris L.), density and width of those ring sections were measured in annual...
• The sensitivity of dormant seeds of mazzard cherry (Prunus avium L.) of Polish provenances to extreme desiccation and/or the ultra-low temperature of liquid nitrogen, LN (−196 °C), was investigated to identify the optimum seed water content (w.c.) at this temperature.
• Germination and...
• Environmental determinants of wood properties variation were examined in Eucalyptus globulus, a globally important hardwood plantation species, in southern Tasmania, Australia.
• Radial variation in wood properties, measured with the SilviScan system, were re-scaled from distance to time...
• Pine seedlings show a marked ontogenetic difference between primary and secondary needles, the latter prevailing with a different timing among species.
• Using the electrolyte leakage method following an artificial freezing test, we aimed at (1) determining the differences in freezing...
• Previously, a large intra-specific diversity and a tight genetic control have been shown for Δ13C (carbon isotope discrimination) in a pedunculate oak (Quercus robur L.) family, which is an estimator for intrinsic water use efficiency (W
i), a complex trait defined as the ratio of net CO2...
• Young coast redwood (Sequoia sempervirens (D. Don.) Endl.) trees were pruned to various heights to examine the effect of pruning severity on epicormic sprouting. Seven separate stands were used with as many as six treatments per stand in coastal Humboldt County, California, USA.
