Under biological conditions plants have to cope with reactive oxygen species (ROS), which often react radically and are therefore responsible for oxidative damage in cells. Normally, the production of ROS is compensated by a defense network consisting of various antioxidants but under unfavorable environmental conditions like drought their production can increase dramatically. As the availability of water is of great importance for plant growth, one focus of this applied work is on the changes of antioxidants in seasoning herbs induced by drought. As there is also an increasing interest of...
