Abstract

To study the effects of different treatments on breaking seed dormancy on Littleseed Canarygrass a factorial experiment based on RCBD with 4 replications was conducted at the Weeds Science Laboratory Ferdowsi University of Mashhad.19 treatments were selected for this experiment. Treatments include: Hot water treatment (50°c for 2, 4 and 6 minutes), treated with sand paper for 5 minutes, concentrated sulfuric acid (3, 6 and 9 minutes), stratification at (5 and 10 °c) for 5 days, concentrated sulfuric acid for 3, 6 and 9 minutes+5 days of stratification, soaking treatments 24, 48, 72 and 96 hours, treatment with potassium nitrate , potassium nitrate+ stratification treatment and control were used for this experiment. The results showed that the effect of light conditions (light / dark and constant darkness) and the effect of different treatments on seed dormancy and two light regimes on the littleseed Canary grass seed germination, but the study of treatments for the seeds to sleep Canarygrass was observed a significant difference at p
