Abstract: 

The main purpose of this study was to determine the best treatment for Colutea persica seeds to break their dormancy and better regeneration. Applied treatment Includes: soaking seeds in Sulfuric Acid solution (98%) for half an hour, scratching treatment, two and four weeks cooling, using Gibberellic Acid and cooling treatment simultaneously for two weeks and finally using distilled water as reference control. Statistical analysis was conducted randomly by using five replicates (with 10 seed samples in each one) in Lab conditions. Number of germinated seeds was evaluated in different treatments. The data were analyzed using Duncan’s test at level of 5% probability by SPSS software package. Results demonstrated that the highest germination percentage (Gp) and Germination rate (Gr) was found in seeds for which scratching treatment was applied (88% and 8%, respectively). In addition, the results revealed that hindrance in budding process occurs due to the impermeability of the seed coat. Moreover, no dormancy in embryo was observed in this species.
