| Abstract/Contents: | The presence of a reservoir of dormant viable seeds in the soils of arable fields in Britain has been recognized for a long time (Brenchley, 1918; Chippendale and Milton , 1934; Milton, 1943; Champness and Morris, 1948), and it is known that the seeds of flowering plants such as Tanunculus repens, Juncus effusus and Poa annua often accumulate in the soil in very large numbers. High densities of dormant seeds are by no means confined to farmland; very large numbers of seeds of perennial grasses, sedges, rushes and shrubs often accumulate in the soils of pastures, heathlands and marshlands. Not all flowering plants develop persistent seed banks. Familiar species such as Tussilago farfara, and willows (Salix spp.) produce seeds whivch are exceedingly short-lived and germinate rapidly on contact with moist soil. Many of the commoner grasses of the British flora appear to germinate soon after they are dispersed or after a relatively short period of dormancy whilst lying on the soil surface. Recent evidence (Thompson & Grime, 1979) shows that plants growing together in the same habitat can differ widely in the persistence of their seeds. In order to explain why plant species occupying the same habitat may show such great differences in seed persistence, it is necessary to consider the adaptive significance of dormancy in the various types of seeds and seed banks which occur in the British Isles. In the past ten years a great deal of field and laboratory work has been conducted in this country on the dormancy and germination characteristics of the seeds of native plants. This research has now reached the stage where it is possible (1) to develop a simple classification of seed banks, (21) to begin to describe the functioning of each type of seed bank and (3) to use this information to manipulate the regeneration and species composition of vegetation. |
