Plant cryopreservation consist of the storage of seeds, pollen, tissue, or embryos in liquid nitrogen. This method can be used for virtually indefinite storage of material without deterioration over a much greater time-period relative to all other methods of ex situ conservation.
in situ, which consists in managing populations on-site, dynamically evolving in their natural environment. [6] [7] In situ methodologies include: conservation in natural populations (in nature) on farm conservation; ex situ, which consists in conserving individuals or populations out of their natural environments. Ex situ gene bank ...
In-situ conservation involves the creation of National Parks, National Forests, and National Wildlife Refuges as a way of preserving the natural habitat of the targeted seed-producing organisms. In-situ conservation of agricultural resources is performed on-farm. This also allows the plants to continue to evolve with their environment through ...
In-situ conservation is the on-site conservation or the conservation of genetic resources in natural populations of plant or animal species, such as forest genetic resources in natural populations of tree species. [1] This process protects the inhabitants and ensures the sustainability of the environment and ecosystem.
Plant conservation strategies generally combine elements of conservation on farm (as part of the crop production cycle, where it continues to evolve and support farmer needs), ex situ (for example in gene banks or field collections as seed or tissue samples) or in situ (where they grow in the wild or protected areas).
This method can be used for virtually indefinite storage of material without deterioration over a much greater time-period relative to all other methods of ex situ conservation. However, cryo-conservation can be an expensive strategy and requires long term hygienic and economic commitment for germplasms to remain viable.
The Centre for Pacific Crops and Trees (CePaCT) plant gene bank in Suva, Fiji, focuses on propagating (and re-propagating) seedlings of plants (using clippings and tissue culture, rather than as seeds), to preserve the genetic diversity of the most important varieties of food crops of the Pacific region, such as banana, taro, breadfruit and yam.
Target 8: At least 75% of threatened plant species in ex situ collections, preferably in the country of origin, and at least 20 per cent available for recovery and restoration programmes. Target 9: 70% of the genetic diversity of crops including their wild relatives and other socio-economically valuable plant species conserved, while respecting ...
