Context: There is an increasing concern over predications that the world population will reach 8 billion in the next 25 years. Currently, many regions in Africa and Asia are experiencing a food crisis that is contributing to hunger, malnutrition and starvation. So each way to increasing yielding plant is a key factor to respond this demand. There are several elicitor to reach this target. Polyamines (PAS) are lightweight molecular that are present in all living organisms. PAS are necessary for the growth of prokaryotes and eukaryotes. Putrescine (Put), spermidine (Spd) and spermine (Spm) are the major PAS in plants. In plant cells, Put (diamine) is synthesized from ornithine and arginine by ornithine decarboxylase and arginine decarboxylase, respectively. With regard to the significance of the flower and oilseed of safflower, this research has been done on Put and its effect on the growth and development of safflower. Discussion :This experiment included three separate plans (A, B, C) and each plan has two different culture mediums that were called 'a' and 'b'. Finding and Conclusion: In this work, we found that maximum shoot regeneration belonged to Put A4 and Put A2 (Plan A). Also, the third plan has a significant reduction rather than first and second plan regarding rooting. According to data, the group with the highest shoot regeneration (A plan-Put A4) had maximum peroxidase activity also and the treatments of B plan with the lowest shoot regeneration had lowest enzyme activity.
