- Intervention effect Heat increased boll abscission relative to normal temperature.
- Intervention effect Under heat, 1-MCP increased cotton yield by 101.4–141.7%.
- Intervention effect Yield with heat plus 1-MCP remained significantly below normal temperature.
- Intervention effect Boll weight with heat plus 1-MCP remained significantly below normal temperature.
- Intervention effect Boll number with heat plus 1-MCP remained significantly below normal temperature.
- Intervention effect 1-MCP mitigated heat-induced photoinhibition in the leaf subtending the boll.
- Intervention effect 1-MCP increased Fv/Fm, ΦPSII, and electron transport rate in the subtending leaf.
- Intervention effect 1-MCP reduced non-stomatal limits to photosynthesis.
