Hi, I wondered if anyone had microwaved pollen and then had a look with a microscope at the effects - and you could then decide how much power to apply. There is a maybe relevant paper about microwave drying but not for pollination: http://jstor.org/stable/1222270/… Behind a knowledge wall but for free if you register, and quite a bit is visible on the above link.
