Effects of Ethyl Methane Sulphonate Treatment on Ginseng Seeds

Ethyl Methane Sulfonate처리 인삼종자의 생물학적 효과

In order to clarify the biological effects of chemical mutagen, ethyl methane sulphonate (EMS), in M, seedling(Ponax ginseng C. A. Meyer) . the dehiscent seeds of ginseng were treated with EMS for 12 hours at 20t and Post-washed for 24 to 72 hours. The differences of biological injuries in M, generation due to the concentration of EMS were quite obvious in rate and date of germination, stem length, stem diameter, leaf length, leaf width, root length, root diameter, and root weight . Especially, the seeds treated with the high concentration of EMS , above 0.8%, were not germinated The growth injury was directly proportional to the concentration of EMS but not relative to the post-washing time of afire 25 hours. The useful range of EMS concentration and post-washing time in ginseng seeds were 0.4 % - 0.6% and above 24 hours, respectively.
