Abstract
Since gamma rays level in atmosphere occasionally increases affecting biosphere,the radiation effect damages seriously certain plant species. This study was focused on a grassy species,Triticum aestivum, in comparison to a forestry species, namely Quercus robur. Young plantlets were exposed to weak gamma rays delivered by a laboratory {sup 60} Co source, for different irradiation times. The enzymatic activity of catalase was evaluated using biochemical methods. Triticum aestivum presented a slight enhancing of catalase, both in caryopsides and leafs. Quercus robur revealed a rapid linear enhancing of catalase in saplings cultivated in laboratory while saplings grown in forestry were characterized by a reduced catalase activity. Concurrent phenomena of enzyme biosynthesis stimulation and enzyme structure damage are presumed to be the cause of such behavior. (authors)
