Abstract: Canebrakes (stands of Arundinaria gigantea) provide exceptional wildlife habitat, promote stream bank stabilization, and improve water quality, making them ideal focal points for riparian restoration projects. However, availability of viable seed for seedling production is limited due to infrequent flowering events, naturally low seed viability, recalcitrant nature of seed, and failure of flowering stands to produce seed. The purpose of this study was to examine seed storage methods to extend stored seed viability and seed germination for future use in rivercane seedling production for restoration programs. To test for effect of container type, seed viability and percentage germination were compared for 2 storage container types (paper and plastic bag) at 2 storage temperatures (5 C and 21 C ) over 5 months. To test for effect of storage temperature, seed viability and percentage germination were compared over 3 storage temperatures (-5, 5, and 21 C). Seed viability decreased over time independently of container type or storage temperature. Plastic bags demonstrated a greater percentage germination than paper bags, but viability showed no difference. The greatest viability and percentage germination among storage temperatures occurred at ‐5 C, and no differences were observed for 5 and 21 C. These results suggest that rivercane seed germination potential can be prolonged by storage in plastic bags at sub-zero temperature.
