“…Soil seed banks vary much according to seed proximity, seed persistence and physiological state. Living seeds have been found in or on the soil for different durations (Duvel, 1902;Priestley, 1986;Roberts, 1986;Poschlod et al, 1998), different seasons (Roberts, 1986;Poschlod and Jackel, 1993;Milberg and Andersson, 1997), at different depths (Duvel, 1902;Grundy et al, 2003;Benvenuti, 2007), in different quantities (Thompson and Grime, 1979;Thompson et al, 1997) and in different states of dormancy or procession to germination (Baskin and Baskin, 1998;Walck et al, 2005; Finch-Savage and Leubner-Metzger, 2006). Seeds in the soil seed bank may occur in or on the soil, but in many situations, there is a continuity between seeds at the surface, partly buried and completely buried seeds (Thompson, 2000;Benvenuti, 2007).…”

This chapter covers the types and definitions of soil seed banks; evolution of soil seed reservoirs as affected by seed characteristics (seed density and size), and biotic (including fungi and seed predators) and abiotic (such as soil fertility and water content) factors; the functional role of seed banks in the dynamics of natural communities; and the adaptive traits necessary to build up soil seed banks.

“…Patterns and variation of soil seed banks have long been of much popular interest 8 . Despite the extremely heterogeneous nature of soil seed banks 9 , most studies have been conducted at the local scale, which hampers our general understanding of the assembly processes of this biodiversity reservoir at large scales 10 .…”

Soil seed banks represent a critical but hidden stock for potential future plant diversity on Earth. Here we compiled and analyzed a global dataset consisting of 15,698 records of species diversity and density for soil seed banks in natural plant communities worldwide to quantify their environmental determinants and global patterns. Random forest models showed that absolute latitude was an important predictor for diversity of soil seed banks. Further, climate and soil were the major determinants of seed bank diversity, while net primary productivity and soil characteristics were the main predictors of seed bank density. Moreover, global mapping revealed clear spatial patterns for soil seed banks worldwide; for instance, low densities may render currently species-rich low latitude biomes (such as tropical rain-forests) less resilient to major disturbances. Our assessment provides quantitative evidence of how environmental conditions shape the distribution of soil seed banks, which enables a more accurate prediction of the resilience and vulnerabilities of plant communities and biomes under global changes.

Dormancy and Germination in Seeds of Common Ragweed With Reference to Beal's Buried Seed Experiment

Common ragweed (Ambrosia artemisiifolia L.) was one of 19 herbaceous weedy species used by Beal in his buried viable seed experiment started in 1879. No seeds germinated during the first 35 years of the experiment when germination tests were performed in late spring, summer or early autumn. Germination did occur in seeds buried for 40 years when seeds were exhumed and tested for germination in early spring. Data obtained in more recent research provide the probable explanation for these results. Seeds of common ragweed that do not germinate in spring enter secondary dormancy by mid to late spring and will not germinate until dormancy is broken the following late autumn and winter. Thus, during the first 35 years of the experiment seeds were dormant when tested for germination, whereas seeds buried for 40 years were nondormant. Seeds buried 50 years or longer did not germinate when tested in spring, probably because they had lost viability and/or seeds germinated during burial and seedlings died.
