Effects of day and night temperatures on grain dimensions
| Treatment |
Day/night temperature (°C) |
Grain length (mm) |
Grain width (mm) |
Grain thickness (mm) |
|---|---|---|---|---|
| HNT | 22/34 | 5·54 ± 0·02a | 3·00 ± 0·03b | 2·07 ± 0·01b |
| HDT | 34/22 | 5·48 ± 0·04a | 3·05 ± 0·03b | 2·21 ± 0·02a |
| CONT | 22/22 | 5·47 ± 0·03a | 3·12 ± 0·02a | 2·12 ± 0·01b |
Values are means ± s.e. Grains were sampled at 24 DAF (n = 12) in high night (HNT) and high day (HDT) temperatures, and 30 DAF (n = 16) in controls (CONT). Values within a column followed by the same letter are not significantly different at P < 0·05 (Tukey–Kramer's multiple range test).
