Other claims from this paper (10)
- Intervention effect Sugarcane photosynthetic responses to light intensity and intercellular CO2 differed between fertilized and non-fertilized treatments.
- Intervention effect Normally, 180 N sugarcane had significantly higher photosynthetic rates than 90 N, but the difference was not significant under drought.
- Intervention effect Normally, 270 N sugarcane had significantly higher photosynthetic rates than 90 N, but the difference was not significant under drought.
- Intervention effect The 0 N treatment had the lowest sugarcane photosynthetic rates under both water conditions.
- Intervention effect Higher nitrogen application supported higher photosynthetic rate, stomatal conductance and chlorophyll content in sugarcane.
- Mechanism The authors attribute higher photosynthetic rate, stomatal conductance and chlorophyll content to higher nitrogen concentration accumulated in sugarcane leaves.
- Intervention effect Drought significantly reduced sugarcane leaf area and biomass production.
- Mechanism Higher nitrogen applications with larger root systems could support higher photosynthetic activity and greater dry mass accumulation in sugarcane.
- Association Photosynthetic and biomass nitrogen use efficiency had a strong positive coefficient with drought tolerance index in sugarcane.
- Mechanism The authors suggest higher nitrogen use efficiency could help sugarcane tolerate drought stress.
