t0“Abscission of mango fruitlets”
e1“Intact fruitlets and their pedicels exhibited 276% and 341% higher total free polyamines than about-to-abscind ones in ‘Kensington Pride’, whilst in ‘Glen’; the increase was 137% and 63%, respectively”

- Association Intact fruitlets of Kensington Pride had 276% higher total free polyamines than about-to-abscind fruitlets.
- Association Intact pedicels of Kensington Pride had 341% higher total free polyamines than about-to-abscind pedicels.
- Association Intact fruitlets of Glen had 137% higher total free polyamines than about-to-abscind fruitlets.
- Association Spermine concentrations in Kensington Pride fruitlets were higher in intact tissue (220 nmol g-1 FW).
- Association Spermine concentrations in Kensington Pride pedicels were higher in intact tissue (172 nmol g-1 FW).
- Association Spermidine concentrations in Glen fruitlets were greater (244.5 nmol g-1 FW).
- Association Spermidine concentrations in Glen pedicels were greater (256 nmol g-1 FW).
- Association About-to-abscind Kensington Pride fruitlets had very low spermine levels (10.4% of intact fruitlets).
- Association About-to-abscind Glen fruitlets had very low spermine levels (19% of intact fruitlets).
- Mechanism Spermine seems to be critical in mango fruitlet abscission.
- Intervention effect Exogenous polyamine applications reduced fruitlet abscission during the initial heavy abscission period.
- Intervention effect Spermidine (0.1 mM) applied at fruit set reduced fruitlet abscission by 6.8% compared with the control.
- Intervention effect Spermine (0.1 mM) sprayed at panicle 5-8 cm showed the least fruitlet abscission (91.5%) compared with controls (95.5%) six weeks after fruit set.
- Intervention effect Inhibitors of polyamine biosynthesis accelerated fruitlet abscission.
- Mechanism Polyamine biosynthesis plays a key role in mango fruitlet abscission.
