Studies of Phenological Forms of Pedunculate Oak

Contemporary Problems of Ecology, 2017
We review the specificity of early and late phenological types of pedunculate oak differing in the spring flushing of leaves, namely, its occurrence in topographical elements, soil conditions and hydrology, responses to weather, and vulnerability to unfavorable factors.

Root analysis in stands of beech, hornbeam–pedunculate oak and Turkey oak

Agrokémia és Talajtan, 2011
Három klímajelző fafajú – egy bükkös, egy gyertyános–kocsányos tölgyes és egy cseres – faállományban végzett összehasonlító gyökérvizsgálatok eredményeit mutatja be a dolgozat. Az állományok talajtani és hidrológiai tulajdonságai többé-kevésbé megegyeznek. Klímájuk azonban különbözik, a bükkös a legnedvesebb, a cseres pedig a legszárazabb adottságú.

The importance of variance and microsite conditions for growth and hydraulic responses following long-term rewetting in pedunculate oak wood [PDF]

Trees - Structure and Function
Key message Early rewetting influenced growth variability and hydraulic uniformity in Pedunculate oak wood on disturbed peatland. Long-term study highlighted vessel widening's importance in adapting to water availability changes.

Quercus robur L. (Pedunculate Oak)

1996
The genus Quercus consists of about 450 species distributed throughout North temperate regions, the Mediterranean basin, and some montane tropics and subtropics. Although recent phylogenetic studies have provided the basis for an infrageneric classification of the genus, the species distribution in the Quercus complex is still a matter of debate (Nixon

Physiological Response of Pedunculate Oak Trees to Gall-Inducing Cynipidae

Environmental Entomology, 2018
Gall-inducing Cynipidae (Hymenoptera) manipulate the leaves of their host plants and induce local resistance, resulting in a diversity of physiological changes. In this study, three gall morphotypes caused by the asexual generation of Cynips quercusfolii L., Neuroterus numismalis (Fourc.) and Neuroterus quercusbaccarum L.

On the Prostrate Growth Form of the Pedunculate Oak

Лесоведение / Forest Science
Studying the plasticity of tree life forms helps to understand the mechanisms ensuring the stability of their populations in forest communities. The object of the study is the prostrate life form (trailing shrub, ‘stlanec’) of the pedunculate oak (Quercus robur L.).

The genetics of exapted resistance to two exotic pathogens in pedunculate oak

New Phytologist, 2019
Summary Exotic pathogens cause severe damage in natural populations in the absence of coevolutionary dynamics with their hosts. However, some resistance to such pathogens may occur in naive populations. The objective of this study was to investigate the genetics of this so‐called ‘exapted’ resistance to two pathogens of Asian origin (Erysiphe ...

Protection forests of pedunculate oak

2003
Hrast lužnjak čini najvrjednije šume u Hrvatskoj. Ta je vrsta podložna utjecaju štetnih biotskih i abiotskih čimbenika zbog čega dolazi do masovnih sušenja. S obzirom na to hrastove se šume zaštićuju punih 100 godina. Današnja se praktična zaštita šuma hrasta lužnjaka svodi na zaštitu od štetnih kukaca, gljiva, sitnih glodavaca, divljači i korova. Među

Natural regeneration of pedunculate oak

2007
Forest management in Croatian lowland forests is generally based on the natural regeneration of forest stands on the dynamics of natural forest. The paper brings an assessment of silvicultural procedures implemented in the natural regeneration of pedunculate oak.

Temporal mortality pattern of pedunculate oaks in southern Sweden

Dendrochronologia, 2007
Abstract Decline of the oak forests decline in southern Sweden has been reported for more than two decades. Little empirical data exists, however, to study the temporal pattern of the phenomenon in detail. In this study we quantified the temporal pattern of non-windfall oak mortality by analyzing the dataset of 44 dendrochronologically dated dead ...
