In vitro culture of flowering dogwood, Cornus florida, L.

The objective of this study was to determine whether flowering dogwood, Cornus florida, L., may be cultured by in vitro bud culture and micrografting through methods previously established for other woody plants. A low salt medium (Knop's) was necessary for survivability of the explants. Nondormant buds responded to in vitro culture more readily than dormant buds. The 6-benzlaminopurine was superior to kinetin in promoting shoot proliferation. Rooting could not be induced with NAA, lAA, IBA, or IBA in combination with phloroglucinol.
