Fig. 1

Average mature dried grain weight and grain number from primary tillers exposed to high p.a. temperature treatment (35 °C) for different lengths (number of days) from 6daa. Error bars represent the standard error of the means of 8 biological replicates. The ‘C’ label on the x-axis represents the control/no-treatment group. Labelling with different letters indicates significant differences in grain weight between groups according to the LSDs between the means at p < 0.05. Treatments with the same letter had no significant difference between them
