Effect of light during cold-moist stratification on Echinacea (combined E. angustifolia, E. pallida, and E. purpurea) seed germination. The cold-moist stratification treatment consisted of 4 wk at 4 °C under either Inline graphic 24 h of light,Inline graphic 24 h of dark, or Inline graphic 16/8 h of light/dark. Control treatment Inline graphic was not cold-moist stratified. Seed germination was conducted under 16/8 h of light/dark at 25 °C and determined (A) at 3 d and (B) 10 days after removal from the stratification treatment. Control represents seeds germinated under 16/8 h of light/dark at 25 °C but with no stratification. Bars represent the standard error of the mean. Bars with different letters are significantly different at P = 0.05 according to Fisher's test.
