چکیده
  This study investigated the molecular and physiological responses of lemon balm seedlings to the manipulation of nutrient solution with zinc oxide nanoparticle (nZnO) at 0, 100, and 300 mgl-1. The augmentation in biomass accumulation and photosynthetic pigments resulted from the nZnO utilization. The exposure of seedlings to nZnO modifed both primary and secondary metabolism in leaves. The nanosupplements upreguated activities of phenylalanine ammonia lyase and catalase enzymes. Moreover, the incease in concentrations of proline, flavonids, and glutathione resulted from the application of nZnO. ...  بیشتر

چکیده
  To gain insight into metal-based nanomaterials, this study figured out the physiological and molecular behaviors of Melissa officinalis to supplementation of nutrient solution with red nano elemental selenium (nSe; 0, 10, and 50 mgl-1) or bulk Se (BSe). The nSe10 application led to drastic increases in root and shoot fresh weights, and chlorophyll content. While, the nSe at 50 mgl-1 exhibited severe phyotoxicity. Also, nSe10 enhanced uptake and accumulation of Ca and Mg in both leaf and root, contrasted to the nSe50-treated plants. The applied supplements modified phenylalanine ammonia lyase activity, ...  بیشتر
