Other claims from this paper (11)

Observation Only 62% of seed lots had greater than 50% germination.
Observation Of the same lots, 98% had greater than 50% labeled viability.
Intervention effect GA3 significantly increased germination percentage across most seed lots.
Intervention effect GA3 reduced time to 50% germination across most seed lots.
Intervention effect Germination was higher at 20/30 °C than 15/25 °C.
Intervention effect Germination was faster at 20/30 °C than 15/25 °C.
Intervention effect Priming with GA3 and H2O2 improved germination of six species relative to non-primed controls after 14 days.
Observation Asclepias species germinated well across −0.75 to 0 MPa.
Observation Echinacea purpurea needed −0.13 to 0 MPa for optimal germination.
Observation Monarda fistulosa germinated best at −0.13 MPa.
Recommendation The authors recommend GA3 priming for dormancy breaking in restoration programs.
