Seed life span and food security.
Summary Much is known about the inter-specific distribution of life span in a wide diversity of vertebrates and in adult plants, but not for seeds, yet the functional trait seed life span underpins global agriculture, plant species conservation and seed persistence in the soil. We sourced data for five storage...Colville, Louise ; Pritchard, Hugh

The influence of organic and inorganic chelators on the toxicity of bulk and nanoparticles of zinc oxide during germination and seedling growth of Nicotiana tabacum L
Nano and bulk-forms of zinc oxide (ZnO) are used extensively in industry and consequently may accumulate in the environment. However, there is little information available on the comparative effects of these forms during the critical early stages of plant life. Furthermore, the role of chelating agents, which affect the bioavailability...Tirani, Maryam ; Haghjou, Maryam ; Sulieman, Saad ; Colville, Louise ; Ismaili, Ahmad

Wheat seed ageing viewed through the cellular redox environment and changes in pH
To elucidate biochemical mechanisms leading to seed deterioration, we studied 23 wheat genotypes after exposure to seed bank storage for 6?16 years compared to controlled deterioration (CD) at 45?°C and 14 (CD14) and 18% (CD18) moisture content (MC) for up to 32 days. Under two seed bank storage conditions, seed viability was...Nagel, Manuela ; Seal, Charlotte ; Colville, Louise ; Rodenstein, Axel ; Un, Sun …

Seed Longevity—The Evolution of Knowledge and a Conceptual Framework.
The lifespan or longevity of a seed is the time period over which it can remain viable. Seed longevity is a complex trait and varies greatly between species and even seed lots of the same species. Our scientific understanding of seed longevity has advanced from anecdotal ‘Thumb Rules,’ to empirically...Nadarajan, Jayanthi ; Walters, Christina ; Pritchard, Hugh W. ; Ballesteros, Daniel ; Colville, Louise
