pollinia
 

Is there a method to preserve pollinia for future use? I wish to do some hybridization of Bulbophyllums but the flowering times are not synchronized.any info would be greatly appreciated.

I just folded them up in pieces of waxed paper and kept them in the fridge. The longest I have done that and had them remain viable was about a year.

Glassine envelopes used by stamp collectors are also good.

Do not seal them in ziplock bags or anything; they need air.
