Red oak (Quercus rubra) is a fast growing tree which could be met in a various forests in Central Europe and NorthAmerica. In a normal condition, it can live until 300-years and can be 5-6 m tall. Anyway due to the climate change, theoak forest is affected by stress conditions including long period of high temperature and drought.Regarding to volatile organic compounds (VOC) emission, Quercus rubra is a high isoprene and low monoterpenesemitted. The emission is affected by different stress which can be a sensitive signal of stress responses especially in heatstress which can particularly significantly influence all the metabolic processes of the deciduous trees. Our work hasbeen shown that long term heat stress treatments affect foliage photosynthesis as well as different terpene emissions.Under non-stressed conditions, lipoxygenase pathway products LOX emissions were close to detection limit, while instress condition those compounds emission enhanced.
