Germination Ecology of Rorippa Subumbellata (Tahoe Yellow Crest), an endangered, endemic species of Lake Tahoe

Ingolia, M., Young, T. P., and Sutter, E. G. Seed Science and Technology 36:621-632. 2008.

We studied the germination ecology of Rorippa subumbellata Rollins (Tahoe Yellow Cress, Brassicaceae), an endangered perennial plant endemic to the shores of Lake Tahoe (California and Nevada, USA). The effects of light, temperature, cold stratification, dry storage, and dispersal by hydrochory were tested in both greenhouse and growth chamber experiments. Seeds from four collection years (2001, 2002, 2003, and 2004) were either cold stratified for 14, 30, 60, or 90 days or not stratified and incubated in three alternating day/night temperature regimes (13/-1, 18/4, and 24/10°C} for thirty days. Hydrochory and light experiments were carried out in a cool greenhouse (mean temperature 21°C}.
