Fig. 2. — Apical development of seven diploid Brachypodium distachyon accessions exposed to cold (4 °C) for the indicated time. Double-ridge formation was compiled for Brachypodium accessions previously shown to have (A) spring or (B) winter growth habits. Time points where plants never formed the double-ridge structure during the course of the experiment are indicated by an asterisk. Statistically significant differences (P < 0·05) in days to double-ridge values were observed until 28 d for Bd21 and Bd 30-1, until 42 d for Bd2-3 and Bd 3-1 and until 49 d of treatment for Bd1-1, Bd18-1 and Bd29-1.
