Repeated summer drought and re-watering during the first growing year of oak (Quercus petraea) delay autumn senescence and bud burst in the following spring [PDF]

open access: yes, 2016
Climate change predicts harsher summer droughts for mid-latitudes in Europe. To enhance our understanding of the putative impacts on forest regeneration, we studied the response of oak seedlings (Quercus petraea) to water deficit.

Cryphonectria parasitica in Sessile Oak in Hungary

open access: yesActa Silvatica et Lignaria Hungarica, 2007
Since 1999 occurrence of chestnut blight fungus (Cryphonectria parasitica) has been observed in sessile oak in Western and South-Western regions of Hungary in young and middle aged Quercus petraea stands mixed with Castanea sativa. Incidence and impact of the disease, vegetative compatibility type diversity of the pathogen, occurrence of the natural ...

Natural regeneration of sessile oak under different light conditions [PDF]

open access: yesJournal of Forest Science, 2011
Different variants of regeneration felling or different light conditions (total site factor 15-95%) and weed control were evaluated in relation to the 4-year development of individuals of regenerated sessile oak. The regeneration density is not dependent on light conditions. The highest mortality occurs on the open area of clear felling.
