Other claims from this paper (8)
- Intervention effect By the third heat-wave day, soybean specific leaf weight decreased.
- Intervention effect By the third heat-wave day, soybean leaf total nonstructural carbohydrate concentration decreased.
- Intervention effect By the third heat-wave day, soybean leaf oxidative stress increased.
- Intervention effect Soybean photosynthesis, specific leaf weight, carbohydrates, and oxidative stress matched controls about 12 hours after heat waves ended.
- Intervention effect Early pod-stage heat waves reduced soybean seed yield by about 10%.
- Intervention effect Soybean did not compensate for yield loss after late reproductive-stage heat waves.
- Mechanism The authors attribute early pod-stage yield loss more to reproductive impacts than to photosynthesis.
- Recommendation The authors suggest improving soybean reproductive and photosynthetic heat tolerance to mitigate yield loss.
