Abstract
The effects of media type, storage temperature on pollen germination of Hemerocallis spp. were examined. The percentage of pollen germination was higher in all of media type than in the basal medium (sucrose 15% + agar 5%). Especially, GN and GL media including such as CaCl_2, KNO_3 and Ca(NO_3)․H_2O were more effective to improve the pollen germination than the GC medium including only H_3BO_3. Irrespective of species, periodical germination percentage according to storage temperature showed a strong decline from 2days in room temperature storage. In the case of 4C, H. dumortieri and H. thunbergii showed a rapid decline pollen viability from 30days after storage, but the pollen in -20C storage was maintained pollen viability above 40% until 180 days after storage. Since -20C storage for pollen viability is effective, interspecific and intergeneric cross could be possible despite differnet flowering period.
