In vitro Storage
The Gatersleben ex situ collection comprise also species that can be exclusively vegetatively propagated. These include seedless garlic, mint, brassica accessions and highly heterozygous plants as potato that can only be clonally maintained. Traditionally, the maintenance is carried out in the field or in the permanent garden, but includes the risk of pathogen accumulation, pest infestation and extreme climatic conditions.
In the in vitro or 'slow-growth' storage, plants can be, independent of environmental factors, kept for many years. Reduced light, temperature and nutrients decelerate plant growth and enable without sub culturing a storage time up to two years. The Gatersleben in vitro collections comprises currently around 245 accessions that are maintained at 2, 10 and 22°C (Effective 31th October 2018).
