Abstract: (4698 Views)
A completely randomomized design with four replications was used to evaluate the toxicity effects of various nano Fe3O4 concentration (0, 50, 100, 200 and 400 µgml-1) on germination and the growth of radicle, plumule and seedlings of Agropyron desertorum and Agropyron elongatum. Results showed that the germination percentage and seedling growth of both species were reduced using high concentration of nano Fe3O4. The concentration of 400 µgml-1 of Fe3O4 nano particle reduced the germination percentage of A. desertorum and A. elongatum from 95% and 84% to 70% and 45% respectively. 400 µgml-1 of Fe3O4 nano treatment also reduced the seedling growth of A. desertorum and A. elongatum from 8.08 and 11.62 cm to 6.32 and 7.27 Cm respectively. Results indicated that A. elongatum is more sensitive to nano Fe3O4 compared to A. desertorum.
