| Research Abstract |
Experimental restoration of submerged aquatic plants by using 37 soil seed banks collected from Hachiro-ko basin were performed at fields of Akita prefectural Univ. and Eastern curtain drain of Hachiro-ko, Akita. Submerged aquatic plants of 11 species in fields of Akita prefectural Univ. and 4 species in Eastern curtain drain of Hachiro-ko were germinated from soil seed banks respectively. The curly-leaf pondweed as Potamogeton crispus and sago pondweed as Potamogeton pectinatus were tolerant to hyper concentrated cyanobacterial bloom. We clarify the potential of these two species for restoration of aquatic plants in lake shore of Hachiro-ko area.
