Other claims from this paper (11)
- Intervention effect 10 μM melatonin lowered anthocyanin accumulation in strawberry fruit.
- Intervention effect 10 μM melatonin lowered total soluble solid content and fruit colour.
- Intervention effect 10 μM melatonin raised titratable acidity and softening of strawberry fruit.
- Intervention effect Total phenol content was higher in strawberry fruit treated with 10 µM melatonin.
- Intervention effect DPPH scavenging capacity increased in strawberry fruit treated with melatonin.
- Intervention effect Quercetin, gallic and caffeic acid content was higher in strawberry fruit treated with 10 µM melatonin.
- Intervention effect Chlorogenic acid content was higher in strawberry fruit treated with 10 µM melatonin.
- Association Delayed ripening was associated with suppressed H2O2 level and endogenous ABA accumulation in melatonin-treated strawberry fruit.
- Mechanism Lower NCEDs gene expression is the cause of the reduced endogenous ABA accumulation in melatonin-treated strawberry fruit.
- Mechanism Activation of the melatonin ROS scavenging cascade might be responsible for the delayed ripening of strawberry fruit.
- Intervention effect Exogenous application of 10 μM melatonin can slow the ripening of strawberry fruit.
