Hi Millie, Joe, Alberto, and all, I too have used Drierite, zip-top plastic bags, and Eppendorf microcentrifuge tubes for years. I group the anthers in the microcentrifuge tubes, 2 to 4 anthers per tube. I have an expensive drying box; I put the microcentrifuge tubes with their freshly collected anthers in the dry box at least overnight. The microcentrifuge tubes are sitting open in styrofoam microtube racks. I keep blue Drierite in dishes sitting in the dry box with the samples being dried. I put a few microcentrifuge tubes (with their anthers) into a single zip-top plastic bag, and store this in the freezer. I don't keep materials for more than a few years, and the atmosphere inside a freezer (self-defrosting) is probably pretty dry. Still I would like someday to see someone (other than myself) do a careful study of pollen germination for bulbs versus moisture content, storage temperature, and time. You can germinate pollen in dilute sugar solutions and see the pollen tubes grow under a microscope. Percent germination of pollen is what one would measure. For short-term storage, you can store pollen just about any old way. It is when you want to have viable pollen to use a year from now that the details begin to become important. Oh, yes, and I fear that if I tried to regenerate my Drierite in my wife's oven, I'd need to find a new home for myself. It's a lot cheaper to throw the spent Drierite away and buy fresh!
