Other claims from this paper (11)
- Intervention effect Seed growth rate rose from 6.1 to 7.9 mg per seed per day as temperature rose from 18/13 to 27/22 C.
- Intervention effect Seed growth rate did not change further at 33/28 C.
- Observation Excised cotyledons showed a similar temperature response in growth rate.
- Intervention effect Exposure at 33/28 C during flowering and pod set reduced subsequent seed growth rate by 36%.
- Intervention effect Seed respiration on a dry-weight basis was unaffected by temperature.
- Intervention effect Seed-growth duration was unchanged across 24/19 to 30/25 C.
- Intervention effect At 33/28 C seed-growth duration fell by three days.
- Association High-temperature shortening of seed growth coincided with accelerated leaf yellowing.
- Intervention effect Final seed size fell from 200 to 151 mg per seed at the temperature extremes.
- Observation The authors infer seed growth rate and duration are relatively insensitive to 24/19 to 30/25 C after flowering and pod development.
- Mechanism Shorter seed growth at high temperature may contribute to reduced yield.
