An Investigation of Seed Longevity and Antioxidant Changes of Conserved Barley Germplasm
Seed longevity is crucial for the sustainable ex situ conservation of germplasm in genebanks, yet its reliable assessment remains a significant challenge. This research was conducted to predict the longevity of a diverse barley (Hordeum vulgare L.) germplasm collection comprising cultivated and …

PHYSIOLOGICAL CHARACTERIZATION ON SEED AGING OF SIX NATIVE SHRUB SPECIES
… requires a consistent and adequate supply of seeds of native shrubs. However, annual seed production is erratic and seeds are usually short lived and insufficient for the reclamation projects. Seeds of six native shrub species including: Prunus virginiana, Prunus pensylvanica, Arctostaphylos …

A comparative study of the seed bank dynamics of two congeneric alien invasive species
… is threatened by alien Acacia encroachment. The seed bank dynamics of the two most widespread invaders in the region, Acacia saligma and A. cyclops, was studied to elucidate those factors contributing most to their invasive success. This information was then used to assist in developing optimal …

A multi-scale exploration of the drivers and implications of germination strategy in Australian alpine plants
… largely be dependent on the ability of their seeds to germinate, establish and reproduce in situ, or after dispersal to new sites. The effects of climate change on regeneration from seeds may be influenced by intrinsic factors such as seed longevity (how long seeds remain viable and able to …

Relationship between seed dormancy and persistence of seeds of annual ruderal species in the soil seedbank
Knowledge related to seed persistence in soil is critical for weed control decisions in the integrated weed management systems. Many annual weed species have dormant soil seed banks (SSBs), and this may be an important mechanism for seed persistence in these species. Although the relationship …

Floristic homogenization and impoverishment : herb layer changes over two decades in deciduous forest patches of the Weser-Elbe region (NW Germany)
… changes (Chapter 4). Winner species had higher seed longevity, flowered later in the season and had more often an oceanic distribution compared to loser species. Loser species tended to have a higher specific leaf area, to be more susceptible to deer browsing and to have a performance optimum at …
