Ammonium ions affect metal toxicity in chamomile plants
Original language description
The impact of ammonium presence or absence on cadmium (Cd) and nickel (Ni) toxicity in chamomile (Matricaria chamomilla) was studied. Elimination of ammonium elevated tissue water content, amount of soluble proteins and Fv/Fmratio though responses differed between Cd and Ni. Antioxidative enzyme activities (ascorbate- and guaiacol-peroxidase) were also more enhanced in Cd than in Ni treatments without ammonium (in comparison with respective ammonium counterparts). Thiols rather decreased in shoots and increased in roots in the absence of ammonium. At the level of coumarin-related metabolites, ammonium absence typically elevated amount of herniarin glycoside precursor while "stress" coumarin derivative umbelliferone decreased, indicating an additional negative impact of ammonium presence. Subsequently, total soluble phenols and PAL activity were not enhanced by ammonium absence. Mineral nutrients were not considerably affected with the exception of Fe and K that increased preferentially
