Figure 5.

Germination percentages (mean ± SE) of E. songoricum seeds incubated on moist filter paper at five temperature regimes in a 12 h photoperiod following 1–25 months on the soil surface (A) and burial at 3 cm (B) and at 8 cm (C). Different lowercase letters and uppercase letters indicate significant differences in final germination percentages of seeds at different temperature regimes at the same depths and significant differences in final germination percentages of seeds among depths in same temperature regimes (Tukey’s HSD test, P < 0.05).
