Summary Low temperatures may inhibit dormancy break in seeds of winter annuals, therefore it was hypothesized that seeds of Capsella bursa-pastoris and Descurainia sophia that mature at high latitudes in late summer–early autumn would not germinate until they had been exposed to high summer temperatures. Consequently, germination would be delayed until the second autumn. Most freshly matured seeds of both species collected in August and September in southern Sweden were dormant. After 3 weeks…

Differential Germination Response of Navua Sedge (Cyperus aromaticus) Populations to Environmental Factors

The results suggest that the Ingham population may have a greater potential to spread into new areas or become more invasive than the Tablelands population, and the need to integrate flooding with other management tools.

Co-adaptation of seed dormancy and flowering time in the arable weed Capsella bursa-pastoris (shepherd's purse).

In shepherd's purse, early flowering and reduced seed dormancy coincide and appear to be linked, and the weaker secondary dormancy of early-flowering genotypes confers a selective advantage in arable fields.

Abstract: Capsella bursa-pastoris (L.) Medik, shepherd’s purse, is a cosmopolitan summer or winter annual weed species distributed throughout temperate and subtropical regions of the world and is

Germination ecology of Rhynchosia capitata: an emerging summer weed in Asia

The high germination ability of R. capitata under a wide range of ecological factors suggests that this species is likely to be the one to cause more problems in a near future, if not managed appropriately.

Germination Ecology of Two Troublesome Asteraceae Species of Rainfed Rice: Siam Weed (Chromolaena odorata) and Coat Buttons (Tridax procumbens)

Siam weed and coat buttons are among the most troublesome Asteraceae weed species of rainfed rice and were moderately tolerant of salt and water stress, but Siam weed tolerated more stresses than coat buttons.

Seed germination response to high temperature and water stress in three invasive Asteraceae weeds from Xishuangbanna, SW China

It is suggested that seed high-temperature tolerance contributes to the weed attributes of these three species, and that adaptation to local micro-habitats is a critical determinant for invasiveness of an alien plant.

Ecology of the fire-dependent forest herbs Geranium bohemicum and G. lanuginosum in Sweden

The results suggest that to preserve these threatened Geranium species it is advisable to burn nutrient rich forests, since that is where seed banks are most likely to be present and burn when the humus layer is dry enough to be consumed by the fire, to ensure high enough temperature for seed germination to occur.

Germination Ecology of Four African Mustard (Brassica tournefortii Gouan) Populations in the Eastern Region of Australia

Seeds germinated at a wide range of alternating day/night temperatures, suggesting that seeds can germinate throughout the year if other optimum conditions are available, and that the seedbank of B. tournefortii could be managed by tillage regimes that bury its seeds below 8-cm depths and restrict seedling emergence and growth of new plants.



Germination responses of buried seeds of Capsella bursa‐pastoris exposed to seasonal temperature changes

Buried seeds of Capsella bursa-pastoris exhibit an annual conditional dormancy/non-dormancy cycle, germinating in both autumn and spring if seeds are exposed to light.

Temperature requirements for after‐ripening in seeds of nine winter annuals

After-ripening in seeds of winter annuals is fully promoted by high summer temperatures and wholly or partially inhibited by low winter temperatures.

Seasonal variation in dormancy and light sensitivity in buried seeds of eight annual weed species.

Germination in three different light environments (light, dark, and after a short light exposure) in eight annual weed species is recorded, and the patterns suggest that seeds of Papaver rhoeas germinate strictly in the autumn; Capsella bursa-pastoris, Descurainia sophia, Spergula arvensis, and Urtica urens mainly in the spring.

Seed viability and dormancy of 17 weed species after 19.7 years of burial in Alaska

Depth of burial had a significant effect on viability decline of prostrate knotweed, marsh yellowcress, bluejoint reedgrass, and wild oat, and seed dormancy at 19.7 YAB was very low for all species except for American dragonhead, common lambsquarters, Pennsylvania smartweed, and shepherd's-purse, which had seed dormancies of 100, 27, 25, and 38%, respectively.

Seasonal variation in the emergence of annual weeds — an introductory investigation in Sweden

Summary Seeds of thirteen annual weed species were collected in early autumn. Within a few weeks they were incorporated in soil. They were stored either in the field or in climate chambers where
