摘要

Objective:To develop a protocol lor breaking of seed dormancy and increasing the seed germination rate of Bunium persicum.Methods:The seeds were treated with 3.1.6.3.12.5.25.50 and 100 μmol/L of benzyl aminopurine.gibberellic acid（GA,）,thidiazuron（TDZ） and forchlorlenuron.Then,seeds were transferred to two different temperature conditions including room temperature（25 ℃） and chilling temperature（2-5℃）.Results:The treatment of moist seeds with chilling temperature（2—5℃） broke seed dormancy and showed maximum germination,which was 54.7%after 60 d treatment.Also,the treatment of dn seeds with chilling temperature broke seed dormancy with 9.3%germination rate after 120 d.Treatment of seeds with different level of plant growth regulators showed that under moistroom condition,there was evidence ol higher and lower seed germination rate:GA,（100 μmol/L）with 46.7%and TDZ（50 μmol/L） with 6.67%respectively.In addition,the results showed that under moist-chilling condition.TDZ（6.3 μmol/L） with 53.3%seed germination rate had higher influence on breaking seed dormancy.Treatment of seeds with combination of TDZ and GA₃ under moistchilling condition revealed higher rale of breaking of seed dormancy when 6.3 μmol/L TDZ was combined with 100 μmol/L GA,.showing 93.7%genninatiou rate.Conclusions:The effect of plant growth regulators coupled with chilling temperature on breaking of seed dormancy could provide a large number of seedlings while the long juvenile time which is the next restricting factor of plantation still remained.Thus,the subsequent growth of seedlings to provide a large number of corms is necessary for successful plantation.
