Abstract

In this study different concentrations of SiO2 nanoparticles (o, 75, 150, 250, 350, 500 milligram per liter) have been used as a pre-treatment before cold stratification on Sorbus luristanica’s seeds in order to assessment of the nanoparticle potential for simulation of seed germination and growth of the species. For this purpose, the seeds were primed with the nanoparticles for 24 hours and then stratified in sand for 3 months. The experiment was performed as a completely randomized design with 4 replications with 25 seeds in each replication. After 3 month, stratified seeds were transported to germinator and after starting of germination symptoms, germination data were recorded daily for 22 days. The results showed that seed germination under 250 and 350 m/L NSiO2 treatments improved around 100% while seed germination in control seeds was 26%.
