Other claims from this paper (5)
- Association Rice cultivars with fast leaf color-changing had higher NH3 volatilization loss.
- Mechanism The higher NH3 volatilization loss of fast leaf color-changing rice cultivars is attributed to higher apoplastic NH4+ concentration and NH3 compensation point together with lower glutamine synthetase activity.
- Intervention effect N application delayed leaf color change in rice.
- Intervention effect N application increased NH3 volatilization in rice.
- Recommendation Selecting rice cultivars with slow leaf color-changing and managing fertilization to delay leaf color change could reduce N gas loss and increase N use efficiency.
