Table 1.
The grain weight and contents of starch and protein at maturity under ambient and high-temperature conditions in two years.
| Year | Temperature | Grain dry weight (mg grain−1) | Starch content (mg g−1) | Starch accumulation (mg grain−1) | Protein content (mg g−1) | Protein accumulation (mg grain−1) |
|---|---|---|---|---|---|---|
| 2014 | Control | 222.2 a | 627.0 b | 139.3 a | 82.5 b | 18.3 a |
| Heat stress | 178.3 c | 608.2 c | 108.4 c | 94.7 a | 16.9 b | |
| 2015 | Control | 207.1 b | 633.0 a | 131.1 b | 77.6 c | 16.1 b |
| Heat stress | 167.4 d | 612.4 c | 102.5 c | 97.2 b | 16.3 b |
Values are means of three pots (three replicates). Values followed by different lowercases in the same column indicate significant differences among treatments at P < 0.05 level (LSD test).
