“…Habitat types that have been infested by ragweed for decades, like abandoned fields in N-America, have a load of 0-200 ragweed seeds per m² even when sampling only the persistent soil seed bank in summer (Rothrock et al 1993). Bigwood and Inouye (1988) found on average 36 ragweed seeds per m 2 in the upper soil (0-8 cm) and 57.6 seeds per m 2 at a depth of 8-16 cm in an old field in Maryland (US).…”

NeoBiota 28: 39-49. doi: 10.3897/neobiota.28.6838 Abstract Ambrosia artemisiifolia is an invasive annual herb infamous for the high allergenicity of its pollen, which is related to increasing medical costs. Additionally, it can cause serious yield losses as agricultural weed. Common ragweed seeds accumulate in the soil and can remain therein viable for decades, which poses a problem for the sustainable management of these populations. A long term management should thus target a reduction of the soil seed bank. We observed the influence of four different mowing regimes on the ragweed soil seed bank at six roadside populations in eastern Austria. The mowing regimes were based on methods from common roadside management practice and specifically adapted to reduce seed production. After three years of application, the soil seed bank was indeed reduced by 45 to 80 percent through three of the four mowing regimes tested. Therefore, we suggest that the best mowing regime for the most effective reduction of the size of the soil seed bank is the one consisting of one cut just after the beginning of female flowering (around the 3 rd week of August in Eastern Central Europe), followed by a second cut 2-3 weeks later.

“…However, in large-scale surveys such as in this study it is not practical to make a complete enumeration of soil-stored seed followed by seed viability tests. The direct germination procedure used here is efficacious, time efficient, and gives ecologically meaningful estimates of the seed bank (Gross 1990;Rothrock et al 1993). This technique is particularly suitable for the detection of persistent seed banks in which component seeds are more than one year old (Thompson & Grime 1979).…”

The relationship between the soil seed bank and above‐ground vegetation of a coastal barrier island

. The germinable soil seed bank is described from a coastal barrier island off the northwest coast of Florida, USA. Soil samples collected from seven vegetation types, recently deposited dredge spoil and unvegetated areas in autumn 1990 and spring 1991 were placed out in greenhouse trays. 110 taxa germinated from the samples with the largest number (41) being C3 perennial dicots. The largest number of taxa germinated from dry (57) and wet (54) swales, the fewest (one species: Heterotheca subaxillaris) from strand. Similarity of seed bank densities to above‐ground species cover was low (Jaccard's Index = 0.36), not different between vegetation types, but higher in the autumn than in the following spring. Compositional gradients in the seed bank and above‐ground vegetation determined using DCA ordination were highly correlated and related to distance from mean high water, and plot elevation. At the landscape scale, the seed bank provided an equally clear delineation of vegetation types to that based upon the above‐ground vegetation. The seed bank of low disturbance, late‐succession vegetation types (wooded dunes, swales, marshes) was well developed (high species richness, emergent density, and percentage annual species) with the exception that the large‐seeded woody species (i.e. Quercus spp.) were absent from the wooded dune seed bank. By contrast, a poorly developed and transient seed bank occurred in more frequently disturbed (extensive sand movement, salt spray), early successional dredge spoil, unvegetated areas and strand. These contrasts support a general pattern of increasing seed bank development and a persistent rather than transient seed bank with decreasing disturbance frequency, increasing time since disturbance and successional maturity.

“…In a corn/soybean rotation in Wisconsin, the seedbank oscillated between 5000 and 10 000 seeds m (2 over a 20-yr period (Bussan and Boerboom 2001). Rothrock et al (1993) found much smaller persistent seed banks in Indiana where size ranged from 152922 to 1994 seeds m (2 . The authors measured a seed bank size of about 164 seeds m (2 10 yr prior to the start of the experiment suggesting that the persistent seed bank of S. faberi is stable.…”

“…In a 30-yr long tillage trial in Ohio, Cardina et al (1998) found that seed banks were larger in no-till soils (1140 seeds m (2 ) when compared with soils that were chisel (210 seeds m (2 ) or moldboard (70 seeds m (2 ) plowed. Tillage reduced seed bank size in the top 5 cm of soil from 139 to 54 seeds m (2 in Indiana (Rothrock et al 1993). After 35 yr of continuous crop rotation and tillage, S. faberi seed banks were found to be highest (6890 seeds m (2 ) in a no-till corn and soybean rotation at one site and in a continuous corn rotation (also 6890 seeds m (2 ) on notill soils at a second site .…”

known as giant foxtail, is an annual graminaceous weed that is native to eastern China, has colonized eastern North America and is expanding its range westward. This species is primarily self-pollinated and the only mechanism of reproduction is by seed. Adult plants may reach 2 m in height and produce over 2000 seeds per panicle. Seeds may possess non-deep physiological dormancy when freshly produced, and can form small persistent seed banks. If not controlled, S. faberi populations can cause severe yield reductions in corn and soybean crops. Several herbicides are available to provide chemical control; however, resistance to some modes of action, (ALS, ACCase, and Photosystem II) have been identified in Canada and the United States. Leaves and seeds of this species provide a food source to several species of mammals, birds, and insects.
