Other claims from this paper (6)
- Observation No seedlings were found within established G. maxima infestations.
- Intervention effect Cold stratification (4 °C) did not enhance seed germination of G. maxima (0.5%).
- Intervention effect Dry storage of seeds at ambient room temperature for eight weeks did not enhance seed germination of G. maxima (2.5%).
- Observation A high proportion of G. maxima seeds that did not germinate were still viable (tetrazolium test).
- Intervention effect After-ripening of G. maxima seeds for 19 months resulted in very high germination (92% mean across three sites).
- Mechanism High seed viability, physiological dormancy, after-ripening germination and vegetative reproduction likely contribute to invasion success of G. maxima in aquatic ecosystems.
