Improving culture initiation of mature oak shoots through use of silver thiosulfate

open access: yesApplications in Plant Sciences, 2022
AbstractPremiseOf 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 cannot be seed banked, and thus rely on alternative strategies such as in vitro culture for ex situ conservation.
