Pri navadni bukvi (Fagus sylvatica L.) in hrastu dobu (Quercus robur L.) smo raziskali anatomske, histokemične in mikrookoljske spremembe po mehanskem poškodovanju. Spremembe vlažnosti po poškodbi smo spremljali s 3D MR slikanjem na živih drevesih in vivo in na segmentih poškodovanih vejic, na katerih smo opravili tudi klasično svetlobno mikroskopi...

The aim of the study was to identify the influence of different widths and cardinal directions of felled corridors on the condition and mensuration characteristics of the English oak trees planted there during the conversion of low-value young stands using the corridor method. The study was carried out in oak forests in the forest-steppe zone at a ...

AbstractMotor-vehicle emissions influence some biochemical and morphological parameters that indicate the vital state of trees in urban plantings. Twenty-eight English oak (Quercus robur) trees growing in places that differing in the level of motor emissions (10−30 m from Moscow Ring Road and the Uzkoye Forest Park in Moscow) have been analyzed for...

In the past, pigs were commonly fed with acorns, and this was of remarkable economic importance. Currently this habit is continued in some areas, especially for production of prime-quality Iberian ham. Mature acorns, after shedding and during storage in unsuitable conditions, can be quickly infected with spores of many moulds, which cause mummifica...

Key messageFew studies have linked the origin of dispersed tree seeds with their post-dispersal fate. We show that habitat-dependent mortality in a pedunculate oak (Quercus roburL.) seedling cohort reshapes the effective fecundity of individual mother trees but has little effect on the cohort’s genetic diversity.ContextInitial tree recruitment play...

Key messageDuring the past decades, a multitude of oak stands have spontaneously established across the pine-dominated landscapes of the French Landes de Gascogne. Yet their future performance under modern climate change is unknown. We show that coppiced, dominant trees are most prepared to cope with drought episodes, displaying higher basal area i...

Here we present a new biomaterial based on cellulose, collagen and polyurethane, obtained by dissolving in butyl imidazole chloride. This material served as a matrix for the incorporation of tannin and lipoic acid, as well as bioactive substances with antioxidant properties. The introduction of these bioactive principles into the base matrix led to...

The aim of the study was to analyze the origin of oak stands within the catchments of the Vorskla’s tributaries and to describe their state. Covering 60,900 ha, pedunculate oak (Quercus robur L.) stands prevail and cover 51.1% of the total forest area of 119,200 ha in the catchment areas of the River Vorskla’s tributaries. The way oak stands are di...

Key messageEfflux-based estimates of stem respiration in oak trees during the dormant season were biased by axial diffusion of locally respired CO2. Light-induced axial CO2diffusion along the stem due to woody tissue photosynthesis may lead to equivocal estimates of stem respiratory coefficients during the dormant season, which are generally used t...
Hrast dob (Quercus robur L.) je poleg gradna najbolj razširjena vrsta hrasta tako v Evropi kot v Sloveniji. V Arboretumu Volčji Potok so v preteklosti že večkrat poskusili z njegovim zasajanjem, vendar je bilo preživetje sadik slabo. Jeseni 2015 so iz Italije uvozili in posadili 49 sadik doba, visokih med 4 in 5 m. Z raziskavo smo želeli ugotoviti,...
