Other claims from this paper (8)
- Intervention effect Combined heat stress and 30 mg/kg soil As reduced shoot and root dry weight of quinoa by 84.1% and 79.1%.
- Intervention effect Combined heat stress and 30 mg/kg soil As reduced stomatal conductance of quinoa by 84.5%.
- Intervention effect Heat stress increased arsenic accumulation in quinoa plants.
- Intervention effect Quinoa treated with 30 mg/kg As failed to reach maturity, with or without heat stress.
- Mechanism Overexpression of antioxidant enzymes partly neutralized oxidative stress in quinoa caused by As and heat stress.
- Observation Arsenic accumulation in quinoa plant parts followed the order root > shoot > grains.
- Intervention effect Human health risks from quinoa grains increased under the combination of As and heat stress.
- Recommendation Cultivation of quinoa genotype Puno is not suitable under high temperatures and contaminated soils with higher As levels.
