Improving soil seed bank management

Pest Management Science, 2018
AbstractProblems 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.

Responses of soil seed banks to drought on a global scale

Science of The Total Environment, 2023
The global increase in drought frequency and intensity in large areas has potentially important effects on soil seed banks (SSBs). However, a systematic evaluation of the impact of drought on SSBs at a global scale has not yet been well understood. We evaluated the effects of drought on SSBs and identified the association key drivers in the current ...

Grazing Effects on Soil Seed Banks: A Global Synthesis

XXV International Grassland Congress (IGC 2023), 2023
Livestock 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, 2012
ABSTRACTSpring 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.

A Guided Tour of the Soil Seed Banks

Contemporary Problems of Ecology, 2023
The soil seed bank could be viewed as an optimization of the chances of the plants to meet favourable conditions in time and in space. Owing to the large amount of publications and the field complexity, available reviews do not cover the entire field. My objective was to produce a synthesis. Determination of the soil seed bank needs careful planning of

Seed banks: Memory in soil

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 ...

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.
