The objective of this study was to determine mineral element concentrations (N, P, K, Ca, Mg, Na, Fe, Zn, Mn, and Cu) in various parts of pedunculate oak acorns to estimate variability in the chemica...
The subject of our research was to verify effects of the mechanical preparation of soil in the natural regeneration of pedunculate oak in a floodplain forest. On the site of a hard-wooded floodplain f...
The analyses of the activity of cambium and the study of the increment of wood during one growing season of pedunculate oak (Quercus robur L.) under conditions of a floodplain forest is provided. The ...
Two adult oak tree groups in northern Serbia, differing in degree of decline, were studied. Measurements of pre-dawn water potential (PWP), nutrient status and radial growth were performed and compare...
In Slovenia, the plant species diversity on 225 research plots dominated by pedunculate oak (Quercus robur L.) and by sessile oak (Quercus petraea (Matt.) Liebl.) has been analysed. Plots of Q. robur ...
Permanent research plotting a crown defoliation survey on pedunculate oak was performed from 1995-2000 every August and included 192 grown trees in every year. On average from 1995 to 2000 conditions ...
In the last decade in Prekmurje, there has been a noticeable decline and physiologically weakening of the pedunculate oak (Quercus robur L.) because of dry climate, unfavourable precipitation patterns...
