Angiosperm nodes are cultured to develop plantlets. The plantlets are exposed to photoperiods of light and dark. Leaf tissue removed from the plantlets when cultured produces at least 20% embryos.

Vitro propagation of grape via leaf disk culture

A process for controlling the development of somatic embryos for either a self-replicative or a vine development mode. Somatic embryogenesis is initiated by placing the embryo in a medium conducive for self-replication. When the embryos have grown to a first stage, they are transferred to a medium with cytokinin activity. They continue to grow until they have grown to a second stage at which time they are transferred to a medium without cytokinin activity until they have grown sufficiently and can be transferred to a non-liquid growth medium.
