- •
Salt stress promotes metabolism of endogenous PA in chrysanthemum.
- •
1.5 mM Spd would be an effective concentration to alleviate salt stress.
- •
Spd alleviates salinity injury via increasing photosynthesis, ROS scavenging ability.
- •
Spd alleviates salinity injury via regulating ionic balance and osmotic potential.
- •
Protective role of Spd was pronounced in sensitive cultivar than in tolerant one.
