Notes: Each species was analyzed separately. Germination is cumulative through 56 and 28 d, respectively, for C. inops and C. tumulicola. Dormancy and viability were calculated after 84 d of germination. The treatment that remained in winter conditions was not included in these analyses. Statistically significant effects (P ≤ 0.05) are in bold. Data are in Figures 2–4.
