A seed bank (also seed banks, seeds bank or seed vault) stores seeds to preserve genetic diversity; hence it is a type of gene bank. [1] There are many reasons to store seeds. One is to preserve the genes that plant breeders need to increase yield, disease resistance, drought tolerance , nutritional quality, taste, etc. of crops .
The seed bank is one of the key factors for the persistence and density fluctuations of plant populations, especially for annual plants. [4] Perennial plants have vegetative propagules to facilitate forming new plants, migration into new ground, or reestablishment after being top-killed, which are analogous to seed bank in their persistence ability under disturbance.
A seed bank stores seeds from plants and is significant in preserving plant genetic diversity. [1] Seed banks can be categorized according to their location and the ecological functions they serve. The primary types include soil seed banks, which are found in terrestrial environments; wetland seed banks, located in aquatic habitats; and canopy ...
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.
Some plants also form smaller tubers or tubercules that act like seeds, producing small plants that resemble (in morphology and size) seedlings. Some stem tubers are long-lived, such as those of tuberous begonias , but many plants have tubers that survive only until the plants have fully leafed out, at which point the tuber is reduced to a ...
The Svalbard Global Seed Vault (Norwegian: Svalbard globale frøhvelv) is a secure backup facility for the world's crop diversity on the Norwegian island of Spitsbergen in the remote Arctic Svalbard archipelago. [5] The Seed Vault provides long-term storage for duplicates of seeds from around the world, conserved in gene banks. This provides ...
The production of plants from seeds that otherwise have very low chances of germinating and growing, e.g., orchids and Nepenthes. To clean particular plants of viral and other infections and to quickly multiply these plants as 'cleaned stock' for horticulture and agriculture. Reproduce recalcitrant plants required for land restoration; Storage ...
Partially shelled popcorn seed saved for planting. In agriculture and gardening, seed saving (sometimes known as brown bagging) [1] is the practice of saving seeds or other reproductive material (e.g. tubers, scions, cuttings) from vegetables, grain, herbs, and flowers for use from year to year for annuals and nuts, tree fruits, and berries for perennials and trees.
