After low-temperature treatment at 8℃ for 12 weeks from October, the plants were cultivated in a greenhouse maintained at a minimum temperature of 15℃. The process of flower bud initiation and development was similar to the plant of Fabaceae and the florets was differentiated until 4 weeks after low temperature treatment. The number of floral shoots was almost all determined at that time. The growth and flowering response were observed in cultivation at a minimum temperature of 15℃ treated after 0, 8, 12, and 16 weeks at 8℃, and the natural low temperature plot. Flowering was accelerated 50 days and more by low-temperature treatment at 8℃ for 12 weeks compared to the natural low temperature plot., E, 4, P, 論文, Article}, pages = {33--38}, title = {ムラサキセンダイハギ(Baptisia australis (L.)
