The role of allelopathy in the invasion of the Chinese tallow tree (Sapium sebiferum) Conference Paper uri icon


  • The rapid transition from grassland to Chinese tallow tree (Sapium sebiferum) woodland may be partly due to allelopathic effects on native plants. A bioassay was performed using aqueous extracts of Sapium or little bluestem (Schizachyrium scoparium) and Schizachyrium seeds. Schizachyrium germination rates and germination timing were unaffected by watering treatments. Growth of Schizachyrium seedlings was significantly facilitated by watering with Sapium extracts versus watering with water. These results suggest that allelopathic effects are not responsible for the competitive success of Sapium in coastal prairies.
