Abstract We carried out preliminary discussion about the effects of storage method，sun light and temperature on germination characteristics of arrowhead（Sagittaria sagittifolia L．）seed，using 4 kinds of genetic arrowhead varieties，including 2 wild-type varieties‘Chaohuyeci’ and‘ Tanglidianci’，and 2 cultivated varieties‘ Zhejiangnongdaci’ and‘ Nanningjiaci’as experimental materials. The result showed that arrowhead seed need to be kept in water， especially in low temperature water， for storage，and dried storage would lead arrowhead seed losing germination ability. Light could significantly improve arrowhead seed germination. The most appropriate conditions for seed germinate were 25 ℃ and 12 h/12 h（L/D）. There existed differences in germination rate of different types of arrowhead seed，the germination rate of wild types were significantly higher than that of cultivated types.
