- •
GABA treatments resulted in lower GAD and higher GABA-T activities in flowers during cold storage.
- •
Higher GABA-T activity resulted in lower GABA content coincided with higher ATP content.
- •
GABA treatments enhanced accumulation of endogenous GB in flowers during cold storage.
- •
GABA treatments enhanced GABA shunt pathway activity which can provide sufficient ATP.
