Auxin (IAA) and soluble carbohydrate seasonal dynamics monitored during xylogenesis and phloemogenesis in Scots pine
(Italian Society of Silviculture and Forest Ecology, 2018)The metabolic activity of phytohormones and the accumulation of carbohydrates affect the reactivation of the cambial zone and the radial increment of woody plants. We aimed to monitor the dynamics of indole-3-acetic acid ... -
Effect of different stand densities on xylem and phloem formation in Norway spruce plantations
(Brill, 2023)Preliminary results of an investigation of the thinning effect on Norway spruce tree growth in terms of xylogenesis and phloemogenesis are presented. Three plots were selected where the stand densities were reduced by ... -
Is the quality of the non-native Douglas-fir wood produced in the Czech forests comparable to native softwoods?
(North Carolina State University, 2019)Important physical and mechanical properties were evaluated for Douglas-fir wood produced in a non-native environment. The specimens were obtained from 15 healthy co-dominant trees growing in three different sites located ... -
Partial asynchrony of coniferous forest carbon sources and sinks at the intra-annual time scale
(Nature Publishing Group, 2024)As major terrestrial carbon sinks, forests play an important role in mitigating climate change. The relationship between the seasonal uptake of carbon and its allocation to woody biomass remains poorly understood, leaving ... -
Stand factors affecting the wood density of naturally regenerated young silver birch growing at the lower altitude of the Czech Republic region
(Výskumný ústav papiera a celulózy, Sekcia Slovenský drevársky výskumný ústav, 2019)The objective of this study was to investigate the basic wood density (rho(k) ) of the silver birch (Betula pendula Roth.) trees in relation to the stand structure. This research was conducted in three stands of different ... -
Temporal and spatial variability of phloem structure in Picea abies and Fagus sylvatica and its link to climate
(John Wiley & Sons, Inc., 2024)Using a unique 8-year data set (2010-2017) of phloem data, we studied the effect of temperature and precipitation on the phloem anatomy (conduit area, widths of ring, early and late phloem) and xylem-ring width in two ... -
Tree-ring width and variation of wood density in Fraxinus excelsior L. and Quercus robur L. growing in floodplain forests
(North Carolina State University, 2018)Oven-dry wood density variations are reported for European ash (Fraxinus excelsior L.) and English oak (Quercus robur L.) trees growing in floodplain mixed forests in South Moravia, Czech Republic. Two sites with different ... -
Xylogenesis and phloemogenesis of Norway spruce in different ages stands at middle altitudinal zone
(Výskumný ústav papiera a celulózy, Sekcia Slovenský drevársky výskumný ústav, 2020)This study aimed to determine the influence of the stand age and selected weather conditions on the cambial activity, xylem and phloem formation and their development. For the analysis, microcores were taken weekly from ...
