I have used refrozen pollen a few times and when pollenation 'took' it 'took' good. But I never tried any beyond the second season because I was always able to replenish with new. A couple had been refrozen twice and it was still OK.
What I'd like to know is if it would be safe to send thawed pollen thru the mail in the winter? So it could be refrozen and used during the next spring? I suspect it would be OK. Anyone have experience with that? Also, what about plastic test tubes or little plastic bottles? Any good? I've always been suspicous of plastic with pollen. Maybe it's just me but when I can smell the odor of new plastic I get suspect.
Oh, I also wanted to add I always put a few grains of rice in my test tubes to keep the pollen from 'caking' (as a dessicant--works good).
