Jahani, Sedighe Saadatmand, Sara Mahmoodzadeh, Homa Khavari-Nejad, Ramazan Ali Effects of cerium oxide nanoparticles on biochemical and oxidative parameters in marigold leaves <p>The effects of suspensions of cerium oxide nanoparticles sprayed onto marigold seedlings (<i>Calendula officinalis</i> L.) at concentrations between 50 and 3200 mg L<sup>−1</sup> were studied. At concentrations of 50 and 100 mg L<sup>−1</sup>, the nanoparticles had a slight positive effect on some growth parameters, but at higher concentrations they caused severe oxidative damage. Activities of phenylalanine ammonia lyase and lipoxygenase increased from 400 mg L<sup>−1</sup> upward, tyrosine ammonia lyase from 1600 mg L<sup>−1</sup>. Ascorbate and glutathione contents decreased from 400 mg L<sup>−1</sup> upwards.</p> Antioxidant defense system;cerium oxide nanoparticles;ecotoxicological concerns;marigold;oxidative stress 2019-05-13
