| Research Abstract |
Euryale ferox, the only species in the genus, is a very large water lily covered with numerous spines on all surfaces. Euryale ferox used to be a harmful plant for farmers who cultivating rice field in Japan. This plant is considered to be relic species and in a fix of the extinction in some areas of Asia as well as Japan. They considered it is difficult to cultivate this species. But I try to cultivate this species for teaching materials. I collected wild Euryale ferox at Saga city, south part of Japan in August-September 2003. After 2 months of cultivation, I succeed to get 549 pieces of seeds. By using those seeds, I tried to study the conditions of sprout of Euryale ferox. Seeds need to store in water to prevent sprout. After cold processing (12C 30 days) and removing the operculum, 13.3% seeds of Euryale ferox sprout at room temperature and higher (20-26C). On the other hand, without cold processing no seeds could not sprout. With cold processing, without removing the operculum 10% seeds sprouted. My experiment revealed it is not impossible for school teachers and students to use this plant for teaching materials.
