In first experiment, seed dormancy was broken using scarification. The results showed that stratification had the highest effect on seeds germination, In second experiment, seeds were planted based on a randomized complete block design in the spring. The methods of seed plarting were pitting, furrow ard surface plarting. Some characteristics including percentage of plant emergence and number of simple and compound leaves were measured in the spring. There were significart differences among three methods in view point of understudy characteristics. Maximum percentage of plant emergence was related to pitting planting with 58.2% and minimum one for surface planting with 38.3%. On the basis of these results, pitting method is better than others for establishment of this plant.
