- •
Salicylic acid treatment ameliorated chilling injury in anthurium cut flowers leading to flowers with lower spathe browning.
- •
Salicylic acid treatment enhanced GABA-T activity which was coincided with lower GABA content.
- •
Salicylic acid treatment enhanced ATP content which was coincided with lower H2O2 content.
- •
Salicylic acid treatment enhanced unSFA/SFA ratio which was coincided with lower PLD and LOX activities.
- •
Salicylic acid treatment enhanced GABA shunt pathway activity leading to consumption of GABA for supplying higher ATP and scavenging H2O2.
