CF Jenner Australian Journal of Plant Physiology 1994. doi:10.1071/pp9940791
Other claims from this paper (11)
- Observation Above 18-22ºC, duration of dry matter deposition in wheat kernels decreased.
- Observation Grain filling rate did not compensate as temperature rose.
- Mechanism Reduced starch content accounted for most loss of grain dry matter at high temperature.
- Association Cell enlargement rate did not increase much as temperature rose.
- Association Grain nitrogen accumulation rate did not increase much as temperature rose.
- Observation Wheat cultivars varied in high temperature tolerance in the low temperature range.
- Intervention effect Above 30ºC, starch deposition was slower than at lower temperatures.
- Observation Reduced starch deposition persisted after transfer to lower temperatures.
- Mechanism Heat reduced soluble starch synthase activity, possibly through denaturation.
- Observation Some endosperm SSS forms may be more heat tolerant than others.
- Observation Enzyme activity was lost rapidly at high temperature and partly restored after cooling.
