Floral differentiation and growth rhythm of rhizome buds of the spring ephemeroid plant Adonis amurensis Regel et Radde Diferenciación floral y ritmo de crecimiento de las yemas de rizomas en la especie primaveral efímera Adonis amurensis Regel et Radde

Spring ephemeroid plants complete their aboveground reproduction and growth during the short growing season, and may go dormant subsequently underground. Little is known about the underground dormancy and biological activities of the plants. In this study, we observed organogenesis and growth rhythm of rhizome buds of Adonis amurensis Regel et Radde, a spring ephemeroid plant from the Changbai Mountains in northeastern China. Our results showed that A. amurensis did not go through summer dormancy, but started producing mixed buds on rhizomes
