RESUMO
Synchronization of somatic embryogenesis was achieved in a carrot (Daucus carota L. cv. “Kurodagosun”) suspension culture by sieving the initial heterogeneous cell population, by density gradient centrifugation in Ficoll solutions, and by subsequent repeated centrifugations at a low speed (50g) for a short time (5 seconds), followed by transferring the cell clusters obtained, which were composed of 3 to 10 cells, to a medium containing zeatin (0.1 micromolar) but no auxin. The frequency of embryo formation reached more than 90%, and synchrony of the embryogenetic process was observed at least in the early stages of the process. The system established in the present work provides a useful system for biochemical research into the mechanisms of somatic embryogenesis.
