Other claims from this paper (13)
- Intervention effect High panicle temperature decreased 1000-kernel weight in three rice varieties.
- Intervention effect Near optimum panicle temperature increased 1000-kernel weight.
- Intervention effect Lower straw temperature improved 1000-kernel weight, less strongly than panicle temperature.
- Intervention effect High panicle temperature reduced grain quality with fewer normal and more opaque, chalky and milky-white kernels.
- Intervention effect High straw temperature increased the soluble nitrogen to protein nitrogen ratio.
- Intervention effect High temperature of both panicle and straw increased the soluble nitrogen to protein nitrogen ratio in straw.
- Intervention effect High temperature of panicle or straw increased total sugar concentrations in both organs.
- Intervention effect High temperature of panicle or straw increased total sugar to crude starch ratios.
- Observation Total available carbohydrate per tiller was greatest at 25/25, followed by 35/25, 25/35 and 35/35.
- Observation Total nitrogen accumulation per tiller was greatest at 35/35, declining through 25/35, 35/25 and 25/25.
- Intervention effect Lower panicle temperature shifted nitrogen accumulation toward panicle and away from straw.
- Intervention effect High temperature induced new tillers with new roots from higher nodes after about two weeks.
- Mechanism The authors attributed reduced kernel weight at high air temperature chiefly to early loss of the panicle receiving function.
