Abstract
Goodarzi G.R., Payam Noor V., Ahmadloo F. (2017): Effects of nanoparticle treatments on propagation of
Prunus mahaleb L. by seed. J. For. Sci., 63: 408–۴۱۶٫
We examined the effects of nanoparticles (NPs) of TiO2 and ZnO at 0.5, 1, 2 or 3% concentrations for 10, 20, and
۳۰ min in stratified seeds of Prunus mahaleb Linnaeus. Then, seedlings produced were irrigated to field capacity
with NP solutions at control, 1, 5, and 10% concentration for 7 months in the greenhouse conditions. Treating
seeds at 1% concentrations of TiO2-NPs for 20 min resulted in the highest germination percentage (65%) and at
concentrations of 3% for 30 min it showed the lowest germination percentage (13%). The highest total seedling
height was obtained after exposure of seeds to 0.5% TiO2-NPs for 10 min. Irrigation of seedlings with TiO2-NPs
at the concentration of 1% seems to be a suitable method how to increase their total height, survival, and total
dry weight. A decrease in the relative water content and an increase in proline were observed in response to the
application of high levels of NPs.
Keywords: germination percentage; growth characteristics; proline; relative water content; seed dormancy; survival
