  Engineered Gold Nanoparticles and Plant Adaptation Potential

  2016915 · In general, plant growth (root length, shoot length, biomass) enhancement has often been observed at the exposure of low concentrations of toxic metal ions and or nanoparticles [ 4, 5 ]. Quite often, hormesis is used to describe such mildly toxic stress-induced stimulatory plant growth response [ 21, 22 ].
