New paper published – Volatile organic compound emissions and photosynthetic parameters of Quercus rubra under temperature stresses

Cooperation between our lab and the former member of our lab, Lucian Copolovici, continues. Another little paper with Astrid and Ülo as co-authors has been published in a rather obscure Romanian journal.

Abstract

Red oak (Quercus rubra) is a fast growing tree which could be met in a various forests in Central Europe and North America. In a normal condition, it can live until 300-years and can be 5-6 m tall. Anyway due to the climate change, the oak 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  monoterpenes emitted. The emission is affected by different stress which can be a sensitive signal of stress responses especially in heat stress which can particularly significantly influence all the metabolic processes of the deciduous trees. Our work has
been 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 in stress condition those compounds emission enhanced.
