Abstract
The purpose of this study is clarification of the growth and development of Oxalis articulata Savigny as a promising ground covers. We examined the effect of day-length and temperature on the growth and flowering of O. articulata. As a result, it was a long-day plant at 20 degree C. It seemed that there was the critical day-length during 12 hours from 13 hours at 20 degree C. In addition, the long-day treatment was able to replace it in night break treatment. On the other hand, the dormancy of O. articulata observed after rainy season in the outdoor culture was considered to be imposed dormancy induced by higher temperature of the season.
