Conventional dry seed storage is unlikely for about one third of all tree species (and nearly
half of evergreen rain forest trees) as they probably produce desiccation sensitive …

Recalcitrant seeds are characterized by desiccation and freezing sensitivity, and short
storage longevity. These physiological attributes obviate their ex situ conservation in …

Background Quercus seeds that are recalcitrant to desiccation and freezing temperatures
cannot be stored in gene banks under conventional conditions. However, the germplasm of …

Embryogenic tissues of Abies alba Mill. were cryopreserved using the slow-freezing
approach. Four cell lines were incubated for 24 h on a medium with 0.5 M sorbitol and pre …

Premise Of the approximately 430 species of oaks (Quercus spp.) that have been assessed,
31% are threatened with extinction and in need of safeguarding. However, oak seeds …

Because conventional seed banking is not an option for oaks, ex-situ conservation requires
living collections and/or tissue cryopreservation. Demonstrated cryopreservation options for …

To adequately meet the challenges of conserving threatened oak species, a wide array of
strategies and techniques are necessary, including ex-situ methods such as in-vitro tissue …
