Other claims from this paper (10)
- Intervention effect Delayed sowing gave a significantly higher photosynthetic rate than normal sowing during the grain-filling stage under heat stress.
- Intervention effect Delayed sowing significantly increased grain weight and yield at maturity compared with normal sowing.
- Intervention effect Delayed sowing significantly reduced the J-step and I-step of the chlorophyll a fluorescence transient (OJIP).
- Intervention effect OJIP parameters ΦPo, ψo and ΦEo were significantly increased under delayed sowing.
- Intervention effect OJIP parameter DIo/CSm was significantly increased under delayed sowing, as listed in the abstract.
- Intervention effect OJIP parameters DIo/CSm and ΦDo were significantly reduced under delayed sowing.
- Intervention effect Among differentially expressed proteins, proteins involved in photosynthetic electron transport were significantly increased under delayed sowing.
- Observation Upregulated proteins in flag leaves of winter wheat included PsbH, PsbR and PetB.
- Mechanism Delaying the sowing date reduced heat dissipation by enhancing the scavenging capacity of reactive oxygen species in flag leaves.
- Recommendation Delayed sowing may be a new cultivation strategy for promoting heat stress tolerance in winter wheat.
