In vitro regeneration from alginate-encapsulated microcuttings of Quercus sp.

Microcuttings with apical and nodal buds from common oak (Quercus robur L.) and Turkey oak (Quercus cerris L.) in vitro clones were encapsulated into an alginate matrix. Apical segments of common oak showed significantly greater in vitro regeneration potential as compared with the nodal ones. Encapsulated Turkey oak nodal segments demonstrated successful regeneration after different periods (2-6 weeks) of cold storage (4 °C), showing no significant deviation from the regenerative frequency of non-cold-treated segments.
