摘要: In vitro culture has enabled a variety of recalcitrant and threatened plant taxa to be micropropagated in the absence viable conventional propagation methods. Cryogenic storage research provided alternative protocols for efficient long-term germplasm many species. Recent advances tissue-culture methods such as somatic embryogenesis have production >20 000 embryos native Australian rush few months, far higher than other these types plants. are reported >30 species vascular plants, seed numerous mycorrhizal fungi (mainly orchid spp.), greatly extending range type material that can stored through application cryogenic The role initiatives botanic gardens biodiversity conservation restoration is discussed, using examples successful ex situ cryogenic-storage research.
