(A) Final germination (mean ± s.e.) of Velleia glabrata seeds at 15/25 °C, 12/12 h light/dark after various durations of DAR, stratification and D/W cycling at 20/34 °C in darkness, and burial 1·5 cm below soil surface in situ. Control seeds (in storage at 15 °C/15 % RH) are also shown. Markers on the x-axis indicate the 48-h wet phases of the D/W cycling treatment. (B) Daily maximum and minimum soil temperatures 1·5 cm below soil surface, (C) daily rainfall, and (D) daily maximum and minimum soil moisture content (% mineral) at seed burial site. Julian days are from November 2005 to March 2006, inclusive.
