Cryopreservation of pollen from two ginseng species - Panax ginseng L. and P. quinquefolium L. - was studied. Freezing anthers that served as pollen carriers to -40 C before liquid N storage affected pollen viability little after liquid N storage. Anther moisture content affected pollen viability significantly when stored in liquid N. The ideal anther moisture content to carry pollen for liquid N storage was 32% to 26% for P. ginseng and 27% to 17% for P. quinquefolium. Viability of pollen from P. quinquefolium anthers with 25.3% moisture content changed little after 11 months of liquid N storage.
