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 …

Thermal thresholds for seed germination in Mediterranean species are higher in mountain compared with lowland areas
Each taxon is characterized by a temperature range over which seed germination is possible and this may vary in space and time in relation to climate and ecological conditions. We used thermal modelling to test the hypothesis that thermal thresholds for seed germination can predict germination timing of Mediterranean species...Picciau, R. ; Pritchard, Hugh ; Mattana, E. ; Bacchetta, G.

Species distribution modelling and seed germination of four threatened snow lotus (Saussurea), and their implication for conservation
Plant environmental envelops and seed regenerative traits of high altitude plants may contribute to competitiveness or endangerment under abiotic conditions that enforce a short growing season. Here, we investigate the factors threatening the existence of four, typical snow lotus species (Saussurea laniceps, S. medusa, S. quercifolia, S. gnaphalodes) endemic to...Peng, Deli ; Sun, Lu ; Pritchard, Hugh ; Yang, Juan ; Sun, Hang …

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

Adaptive significance of functional germination traits in crop wild relatives of Brassica
Functional germination traits contribute to both niche competitiveness and crop yield outcomes. However, there is little understanding of the adaptive significance of the germination thermal- and hydro-parameters in crop wild relatives (CWRs), yet these species are anticipated to be the source of adaptive traits for future agriculture. Seeds of 10...Castillo-Lorenzo, E ; Finch-Savage, WE ; Seal, C ; Pritchard, Hugh
