Open full text 21 citations

Abstract

Changes in the peroxidase (EC 1.11.1.7) and catalase (EC 1.11.1.6) activities, and total chlorophyll, soluble sugars, and ascorbic acid contents of leek leaves treated with the herbicide 1,10-phenanthroline (Phe) in concentrations 0.5, 2.5, 5.0, 7.5, and 10.0 mM have been determined. Plants treated with Phe were characterised by a higher activity of peroxidase and a lower activity of catalase and lower contents of chlorophyll, soluble sugars, and ascorbic acid as compared to non-treated plants.
