The reactive oxygen species are usually generated by normal cellular activities of the aerobic metabolism and play the role of a signal molecule and beneficial growth regulator. When plants are exposed to stress conditions the concentration of reactive oxygen species increases. Therefore, to neutralize these free radicals and to protect cells from oxidative damage enzymatic and non-enzymatic antioxidant systems are activated. In this paper it was investigated the effect of drought on the activities of antioxidant ...

Willow culture for biomass promotes rural development and environmental protection, especially if it is established in areas less favorable for agricultural crops. Researches from this work has been carried out in a wide range of genotypes of Salix sp. cultivated on a deposit of ash resulting from coal burning to Isalnita Power Station, near Craiova, Romania, over a period of ...
