Improving soil seed bank management
Pest Management Science, 2018AbstractProblems associated with simplified weed management motivate efforts for diversification. Integrated weed management uses the fundamentals of weed biology and applied ecology to provide a framework for diversified weed management programs; the soil seed bank comprises a necessary part of this framework.

Grazing Effects on Soil Seed Banks: A Global Synthesis
XXV International Grassland Congress (IGC 2023), 2023Livestock grazing is a major disturbance affecting plant diversity and abundance in terrestrial ecosystems. The intermediate disturbance hypothesis (IDH) predicts that moderate-intensity grazing should produce the highest species diversity, while the Milchunas-Sala-Lauenroth (MSL) model posits that the IDH is valid only for mesic areas.

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.

Canadian Journal of Soil Science, 1995
Approaches used to study seed banks and early publications on them are summarized. Current areas of interest are described, including the balance between herbicide-susceptible and herbicide-resistant seed populations, the effects of reduced tillage, the genetic structure of the seed bank, the role of desiccation, the impact of nutrients, oxygen and ...

Recent advances in soil seed bank research
Contemporary Problems of Ecology, 2013Soil seed bank is an important component of ecosystem resilience and represents a stock of regeneration potential in many plant assemblages. Soil seed banks can be used to predict the composition of new plant recruitment. Species overcome periods of unfavorable weather conditions by building up a large seed bank.

After dispersal most seeds undergo a period of dormancy. Depending on the species and the prevailing conditions, dormancy may last from a few days to many decades (or longer). In some species it is normal for a proportion of the seeds to become incorporated into the soil and become part of a store or ‘bank’ of seeds which can be drawn upon ...

Comparisons of soil seed bank classification systems
Seed Science Research, 2003AbstractSince 1969, ten soil seed bank classification systems have been published. Among these systems, the number of recognized seed bank categories varies from three to twelve. Seed longevity is the main factor used for distinguishing categories, but dormancy and germination types are also important.

Spatial Pattern Analysis of Weed Seeds in the Cultivated Soil Seed Bank
The Journal of Applied Ecology, 1991(1) Spatial pattern of weeds was analysed in an arable-soil seed bank after winter barley. Three hundred samples were taken in a 7-5 x 10m area. Three indices of dispersion (variance-to-mean ratio, Lloyd's mean crowding and Lloyd's patchiness) and the Moran's I statistic of spatial autocorrelation were calculated.
