Title
Effect of zinc oxide nano particles on seed germination and seed vigor in
Festuca ovina under salinity stress
Authors
Abstract
The impacts of different concentrations of ZnO nano particles on seed germination and seedling
growth of Festuca ovina were studied in a randomized completely design with three replications in the
College of Agriculture, University of Tehran, campus of Aburaihan, Iran, in 2018. The experimental
treatments included three concentrations of ZnO nano particles (0, 20and 60 mg/L), three
concentrations of NaCl (0, 50, 100 mM). The results showed that the effects of ZnO nano particles
are significant for DW, FSW and RL. The effect of salinity and ZnO× salinity were significant
for all of the evaluated traits. The maximum FW, DW and FSW were recorded for Zno 20 mg/l+
H2O and Zno 60mg/lc+ H2O. It seems that ZnO nanoparticles can increase the means of these traits
in normal condition but in salinity stress ZnO could not be compensate the harmful effects of NaCl.
Employing ZnO nanoparticles in suitable concentration could promote the seed germination of
Festuca ovina. These findings could further be used for agricultural applications, to enhance the seed
germination and improve the overall yield.
