In this research, the effect of cold plasma treatment on the germination characteristics of Camelina sativa, Kelussia odoratissima, and Heracleum persicum seeds were investigated. An experiment based on completely randomized design with in three replications was conducted. The treatments were three cold plasma power of 40, 60 and 80 W applied on the seeds for 2 minutes and untreated sample was also evaluated as control treatment. The measured traits were: germination percentage and rate, plumule and radicle length. The results showed that cold plasma treatment had a significant effect on germination percentage, germination rate, and radicle length. The cold plasma at 80 kV and 2 minutes improved the germination percentage with increasing it by 10.6%, increasing germination rate by 2.35%, and 3.6 centimeters in radicle length in compared with the control sample. Based on the results obtained from K. odoratissima and H. persicum seeds, cold plasma couldn’t break the dormancy of these seeds, despite the improved hydrophilicity and disinfection of the seeds.
