Antioxidant activity as indicator of UV radiation and other abiotic stress factors on Agaricus bisporus (Lange/Imbach) and Sedum hybridum (L.)

Abstract

Abstract Investigation of stress level might be facilitated also in plant and horticultural sciences, but currently mainly morphological parameters are in use. Antioxidant activity routinely measured in food-oriented researches and several studies indirectly indicated that stress factors can influence this parameter. Our aim was to assess the potential direct indicator role of antioxidant activity in stress conditions. We measured the effects of UVB and soil-delivered stress on Agaricus bisporus and Sedum hybridum. Our results indicate that UVB slightly decreases, while the inadequate soil conditions increase antioxidant activity; hence these measurements are suitable for determining the level of stress in different living samples.
