Seed banks and seed dispersal: important topics in restoration ecology§
Acta Botanica Neerlandica, 1996Restoration ecology deals with the scientific and ecological background of nature management practices aiming at the re-establishment of plant species which have disappeared. As we focus on semi-natural landscapes, these disappearances can be caused by intensification of agricultural practices or cessation of human interference.

We have found that a progressive loss of telomeric sequences occurs from high molecular weight DNA with an increasing appearance at low molecular weight as the periods of storage in the dry state were extended in time to provide seed germination loss from 98 to 0%.

The soil seed bank refers to a reservoir of viable seeds present on the soil surface or buried in the soil. It has the potential to augment or replace adult plants. Such reservoirs have regular inputs and outputs. Outputs are losses of seeds by germination, predation or other causes, while inputs include dispersal of fresh seeds from local sources and ...

Seed features, germination and seed bank
2001Most parasitic weeds produce a large number of seeds per single plant. In context with the requirement for the stimulation of germination this high reproduction forms part of their strategy to survive. Before the last decade, little attention was paid to the reproductive capacity of these weeds, and numerous recent papers refer to non-realistic data on

In part three, on vegetation dynamics, it appeared that many species have become newly established in permanent plots in the study areas. Newly established species in a lot can have been present in the seed bank in the soil before emergence. This is only the case for species with a persistent seed bank sensu Thompson & Grime (1979).

Strategies to conserve Australia’s unique native plant heritage depend on understanding how plant species function. The collection, storage and study of plant germplasm – whether as seed, tissue samples, frozen samples, or whole plants – helps us gain this knowledge. It provides research material to unlock the secrets of seed dormancy in the lab and in

Persistence of Triticale Seed in the Soil Seed Bank
Crop Science, 2012ABSTRACTSpring triticale (×Triticosecale Wittm. ex A. Camus) is being developed as a bio‐product crop for the Canadian prairies and may involve the use of genetic modification. Seed loss before or during harvest from genetically modified (GM) triticale could impact its ability to coexist with conventional crops.

Maximizing the phylogenetic diversity of seed banks
Conservation Biology, 2014Abstract Ex situ conservation efforts such as those of zoos, botanical gardens, and seed banks will form a vital complement to in situ conservation actions over the coming decades. It is therefore necessary to pay the same attention to the biological diversity represented in ex situ conservation facilities as is often paid to ...

Challenges Facing Seed Banks and Agriculture in Relation to Seed Quality
2011Seeds form a convenient vehicle for storage of germplasm, both for agricultural purposes and conservation of wild species. When required, seeds can be taken from storage and germinated, and plants can be propagated for the desired purpose, e.g., crop production or biome restoration.
