1. Sprouting of stems of a subspecies of Paspalum distichum L. “Chikugo-suzumenohie” growing in creeks was investigated in both the overwintering and growing stems.
2. Maximum, optimum and minimum temperatures were 40°C, 35-35°C and 10°C, respectively.
3. All the nodes of the stems except a few terminal nodes showed high sprouting ability.
4. Under the upland field conditions, excised overwintering stems showed the highest rate of sprouting. However, under puddled soil conditions sprouting was absent.
5. Judging from the seasonal changes in the sprouting rate of stems, it appears that the optimum period of control of this wede should extend from the end of May to the middle of June.
