Enhanced inflorescence development in bougainvillea "san diego red" by removal of young leaves and cytokinin treatments



Enhanced inflorescence development in bougainvillea "san diego red" by removal of young leaves and cytokinin treatments



Plant Physiology 54(3): 404-407



Removal of young leaves and application of the cytokinin, N-benzyla-alpha-(tetrahydro-2H-pyran-2yl)-adenine promote inflorescence development in Bougainvillea "San Diego Red". Defoliation greatly increased the amount of assimilate accumulated at the shoot tip 1 to 2 days after treatment. Cytokinin applications further increased the amount accumulated and this increase was apparent 4 days before morphological changes could be detected at the inflorescence axes. Short days promoted inflorescence development and also increased assimilate accumulation at the reproductive axes; thus, it is suggested that the role of short day induction in bougainvillea may be that of redirecting the flow of assimilates, perhaps by its influence on cytokinin synthesis and distribution.
