dose-dependently

Yes, it really depends on dose. Thyme

Thyme is correct.
But, I'm not certain your title is.
If embryogenesis is affected by the dose of microwaves administered, then I would suggest:
Embryogenesis is microwave dose-dependent.
Does this convey the results of your findings?

Thanks a lot JohnParis,
But for me the first version underlines the type of radiation used,
yours is more about embryogenesis itself. Is it correct?
I need to emphasize on radiation. Thanks once more.

You're absolutely right if you're speaking of the radiation used.
I mistakenly thought you were addressing embryogenesis, and not microwave radiation.
Again, what have your results shown? What is the conclusion of your research?

We have stimulating effect on early embriogenesis of very low dose of MW and depressing effect of higher dose. Both are under non-thermal intensity of MW. So, in conclusion we have kind of evidence of dose-dependent non-thermal biological effects of MW.

This is slightly longer, but more to the point (in my opinion).
Dose-dependent non-thermal microwaves and biological effects on (early) embriogenesis.

Thanks once more JohnParis, but for running head I was limited only 50 characters. It's OK. Thanks.

Dose-dependent microwaves: effects on embriogenesis.

Use of the colon is important. It separates the methodology from the results.

Great! Thanks a lot JohnParis

Hi. Just thought I'd mention that the spelling is "embryogenesis," as you used in your original post.
