From: Timing of fire during summer determines seed germination in Mediterranean Cistaceae
Germination percentages (mean ± standard error) of Cistus species after being stored under laboratory control conditions (Control) and at summer temperatures (50/20 °C) (Summer). Seeds were exposed to a heat shock before summer temperatures (or lab conditions) (HB), after summer temperatures (HA), and before + after summer temperatures (HBA). A control without heat shock was also included in the experiment (H −). Different letters show significant differences for seed germination (P < 0.05) between heat shock treatments for seeds exposed to summer and control laboratory conditions, based on pairwise comparisons with the Bonferroni correction after GLM analysis
