Other claims from this paper (7)
- Intervention effect Foliar CK sprays raised total chlorophyll content of rice F67 to 3.25 mg g-1 fresh weight, above SC plants at 2.36.
- Intervention effect Foliar CK sprays raised total chlorophyll content of rice F2000 to 3.65 mg g-1 fresh weight, above SC plants at 2.56.
- Intervention effect Foliar CK application improved stomatal conductance in rice F2000 relative to the heat stress control (499.25 vs 150.60 mmol m-2 s-1).
- Intervention effect Foliar BR or CK sprays reduced MDA content in rice under heat stress.
- Intervention effect Foliar CK had a relative tolerance index of 97.69% under combined heat stress, mainly in rice F2000.
- Intervention effect Foliar BR had a relative tolerance index of 60.73% under combined heat stress, mainly in rice F2000.
- Recommendation Foliar BR or CK applications can be considered an agronomic strategy to ameliorate the negative effect of combined heat stress on rice, according to the authors.
