(1) The tubers of Sagittaria pygmaea Miq. likely had not the dormancy for germination, however, the dormancy was noticed in rooting and vernalization was effective for the dormancy breaking. (2) The tubers which had awaked from dormancy, got emergence under submerged condition possibly at mean atmospheric temperature 14〜15℃. (3) The limit depth for emergence out of the tubers would be about 15cm below the surface of the soil. Emergence from the layers deeper than 10cm was seldom observed. The depth of the tuber-formation was relatively shallow, and almost of them was located at 0-5cm layer. (4) Several herbicides useful for Sagittaria pygmaea Miq. control were found through the screening tests.
