- •
Effect of factors affecting germination were tested on 6 species.
- •
Schoenoplectus germination was best at 32–38 °C in 4 cm water after bleach treatment and cold, wet storage.
- •
94–100% of A. gramineum germinated if pre-treated with bleach after cold wet storage and incubated at 20–30 °C.
- •
Polygonum amphibium (≤13%) and Eleocharis palustris (≤2%) had poor germination.
- •
Polygonum pensylvanicum germination was highest (54%) after 12 months of wet storage, bleach treatment, and incubation at 15–20 °C.
