Smoke-cued Emergence in Plant Species of Ponderosa Pine Forests: Contrasting Greenhouse and Field Results
Smoke-cued seed germination and emergence is common in some frequent-fire ecosystems, but this process is little studied in frequent-fire conifer forests of the southwestern United States. To assess whether aqueous smoke promotes plant emergence in frequent-fire ponderosa pine (Pinus ponderosa
) forests in northern Arizona, I conducted three experiments at different scales (seed, seed bank, and plant community) in both greenhouse and field settings. In the first greenhouse experiment, aqueous smoke significantly increased (P < 0.05) emergence of seeds of 13 % of 61 assayed species. [Read More]
