Other claims from this paper (12)
- Intervention effect Under limited water, photosynthesis and stomatal conductance tended to decrease in the Japanese Egyptian hybrid.
- Intervention effect Transpiration rate did not change significantly under limited water in either parent or F1 hybrids.
- Association PSII maximum quantum yield declined with decreasing soil moisture in the Japanese cultivar, with mean 0.14.
- Association PSII maximum quantum yield declined with decreasing soil moisture in EJ hybrid, with mean 0.16.
- Association PSII maximum quantum yield declined with decreasing soil moisture in JE hybrid, with mean 0.15.
- Intervention effect Severe drought decreased chlorophyll content in both okra parents and hybrids.
- Intervention effect Water stress significantly raised peroxidase and superoxide dismutase activity relative to well-watered plants.
- Observation EJ hybrid had the highest peroxidase activity, 234.9 U/g FW.
- Observation Japanese cultivar had the highest superoxide dismutase activity, 18.69 U/g FW.
- Observation EJ hybrid accumulated 16.7 mg/g DW proline under severe drought.
- Observation JE hybrid accumulated 10.4 mg/g DW proline under severe drought.
- Mechanism EJ hybrid performed more prominently than parents, attributed to stronger antioxidant defense and higher proteins, proline, and chlorophyll.
