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 ...
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 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 ...
A geophyte (earth+plant) is a plant with an underground storage organ including true bulbs, corms, tubers, tuberous roots, enlarged hypocotyls, and rhizomes. Most plants with underground stems are geophytes but not all plants that are geophytes have underground stems. Geophytes are often physiologically active even when they lack leaves.
Storage roots: roots modified for storage of food or water, such as carrots and beets. They include some taproots and tuberous roots. Structural roots : large roots that have undergone considerable secondary thickening and provide mechanical support to woody plants and trees.
The presence of mucilage in seeds affects important ecological processes in some plant species, such as tolerance of water stress, competition via allelopathy, or facilitation of germination through attachment to soil particles. [13] [14] [15] Some authors have also suggested a role of seed mucilage in protecting DNA material from irradiation ...
