Your question is not well written.  I do not understand your question.   For your research  in electromagnetic effect on seeds such as mutations I suggest read on Dr. Robert O. Becker (Cross Current, Body Electric)

Yes. I wrote wrong. At imbibition stage (seed takes water and enzymes and hormones are being active, before seed germination); Under imbibition stage, can electromagnetic area create mutation on embryo?

Thanks sir Adam.

I take into account your propose

This is what I understood.  Just before seed germination stage, seed becomes active by taking in water, enzymes and hormones.  This is called imbibition stage.  Does the seed's exposure (at that stage) to  electromagnetic field mutates its embryonic cells ?  Yes and Becker proved it in his experiments.  Reading his books should give you some clues and references.  Good luck.

Thank you very much. You understood what I want to explain. I have belived it. I take into account your suggestion. Thanks

Not sure if you want to induce mutation or avoid it. If you want to induce, there are better mutagenic agents than electromagnetic field. What crop and what mutations are you seeking? I have added a recent review on the subject. We have ongoing mutation work if you like to visit us.

Thanks Sir Ranjith.

Grape seed, I want trial. I aim that  Rootstock using in viticuture for pyloxera may eliminate.

Thanks for answer and review. I follow you.

Thanks
