Abstract Common groundsel is an alien annual weed that has become increasingly troublesome in many crops in Ohio. Understanding the periodicity of seedling emergence and longevity of seeds buried in the soil may help growers devise more efficient strategies to control common groundsel. Studies were conducted to determine the dormancy status of common groundsel seeds over 24 mo, and to describe the effect of tillage and fertilizer on the pattern of seedling emergence and the rate of depletion of… Expand
Maternal Environment Effects on Common Groundsel (Senecio vulgaris) Seed Dormancy
TLDR
Germination response to temperature in seeds from populations occurring at six sites along a 700-km north–south transect was characterized and signaling of maternal environment varied with inflorescence development stages, meaning the earlier the inflorescences are exposed to cold conditions, the lower the percent germination in F1 seeds.

Seed production and subsequent seed germination of Senecio vulgaris (groundsel) grown alone or in autumn‐sown crops
TLDR
Assessments suggest that the retention of S. vulgaris in arable fields will not pose a major threat to the long-term viability of crop production and may be beneficial to retain it within agricultural ecosystems to enhance overall biodiversity. Expand
Germination, emergence and pyrrolizidine-contents of common groundsel (Senecio vulgaris).
TLDR
For avoidance of seed production before winter (with risk of seed persistence due to cold temperatures), herbs and medical plants or lettuce contaminated with S. vulgaris should not be harvested in late summer or autumn, to avoid contamination with S vulgaris with increased PA contents in the harvested product at the end of the season.

Seed bank modelling of volunteer oil seed rape: from seeds fate in the soil to seedling emergence
Studies were conducted to estimate parameters and relationships associated with sub-processes in soil seed banks of oilseed rape in Gorgan, Iran. After one month of burial, seed viability decreasedExpand
Changes in the Germinability of Seeds of Dicotyledonous Herbs from Anthropogenic and Wild Habitats During Two Initial Years in a Seedbank
TLDR
Changes in seed germinability that occurred during the 2-yr period following burial in the soil are investigated in 116 abundant dicotyledonous herb species to establish differences between seeds collected in “anthropogenic” and “wild” habitats. Expand
How do weeds differ in their response to the timing of tillage? A study of 61 species across the northeastern United States
TLDR
It is suggested that fine-scale variation in the timing of tillage can lead to predictable changes in the species composition and trait distribution of weed communities in annually tilled agroecosystems. Expand
Genetic basis, evolutionary origin and spread of resistance to herbicides inhibiting acetolactate synthase in common groundsel (Senecio vulgaris).
BACKGROUND Following control failure by herbicides inhibiting acetolactate synthase (ALS) in French wheat fields and vineyards, we aimed to confirm resistance evolution and investigate theExpand
A review of the recruitment biology of winter annual weeds in Canada
TLDR
All of the significant winter annual weeds in Canadian agriculture are facultative, with the majority of species emerging at two peak periods, April-May and September-October. Expand
Predicting the potential distributions of Senecio vulgaris L. in China
Predicting potential distribution for alien plants by species distribution model (SDM, or Ecological Niche Model) using occurrence data and habitat environmental variables plays an important role inExpand
Diversity analysis of the rhizospheric and endophytic bacterial communities of Senecio vulgaris L. (Asteraceae) in an invasive range
TLDR
The structure of bacterial communities and their putative function in invasive Senecio vulgaris plants are revealed, which is the first step in investigating the role of plant–bacteria interactions in the invasion of this species in China. Expand

EMERGENCE AND LONGEVITY IN CULTIVATED SOIL OF SEEDS OF SOME ANNUAL WEEDS
TLDR
Initial emergence was greatest with Stellaria media, Senecio vulgaris and Poa annua, and least with Chenopodium album and Thlaspi arvense, and the numbers of seedlings which emerged each year declined at a rate which was constant for each species. Expand
Ecology of Capsella bursa-pastoris (L.) Medik. and Senecio vulgaris L. in relation to germination behaviour.
TLDR
In some cases it has been shown that a population of seeds, even from a single plant, contains distinct groups with different physiological responses which may (or may not) be correlated with morphological differences. Expand
Sources of viable seed loss in buried dormant and non-dormant populations of wild oat (Avena fatua) seed in Colorado.
TLDR
Buried populations of dormant and non-dormant wild oat (Avena fatua) seed persisted less than 2 years, depth of burial having very little influence on their survival, according to their depth in the soil. Expand
PERIODICITY OF SEEDLING EMERGENCE AND SEED SURVIVAL IN SOME UMBELLIFERAE
TLDR
There were differences both in the times of year at which seedlings emerged and in the extent to which seeds survived in cultivated soil among ten species of Umbelliferae, including Sison amomum, Conium maculatum and Torilis japonica. Expand
Seed dormancy in Mediterranean Senecio vulgaris L.
TLDR
The innate dormancy exhibited by seed of non-radiate Mediterranean S. vulgaris, enables the species to adopt a winter annual life cycle which is typical of Mediterranean ephemerals. Expand
ANALYSIS OF THE GERMINATION SYNDROME OF DUNE ANNUALS
TLDR
It is concluded that the general drought avoidance syndrome results from species-specific physiological mechanisms and the optimum germination temperatures and the percentage of dormant seeds at the end of the experiment. Expand
The biology of Canadian weeds. 123. Senecio vulgaris L.
TLDR
A rust pathogen, Puccinia lagenophorae Cooke, is currently being evaluated for control of S. vulgaris, which produces pyrrolizidine alkaloids that have been implicated as a cause of liver toxicity in livestock. Expand
Environmental control of dormancy in weed seed banks in soil
TLDR
The different factors that affect dormancy in weed seed banks in soil are discussed, aiming to set a conceptual basis that will facilitate the construction of predictive models and stress the importance of clarifying the interaction between soil thermal and hydric conditions in the modification of the degree of dormancy of seed populations. Expand
Common groundsel, Senecio vulgaris L.
TLDR
Groundsel, native to Europe, is now common throughout the temperate regions of the world, but most common west of the Cascade Mountains, and is especially a problem in forage crops because it is toxic to livestock. Expand
Factors involved in the dormancy and germination of Capsella bursa-pastoris (L.) Medik. And Senecio Vulgaris L
TLDR
A laboratory investigation into the dormancy and germination behaviour of the two species in relation to some of the major factors which are likely to affect seed germination in the soil. Expand
