Is Oxidative Stress The Cause Of Death When Recalcitrant Spartina Alterniflora Seeds Are Dried?, James Hammond Chappell
LSU Doctoral Dissertations
Recalcitrant seeds, which die when desiccated, can be difficult to study because of their generally large size, high metabolism, and poor storage properties. However, recalcitrant seeds from the salt-marsh grass Spartina alterniflora are unique when compared to most other recalcitrant species because the seeds are dormant and small; Spartina pectinata and S. spartinae, which produce orthodox seeds, can be used as controls. Because of these somewhat rare characteristics, S. alterniflora is a good model system to study recalcitrance. In the present study, the following physiological parameters were examined: Cardinal temperatures for germination, a viability test to determine if seeds are …
