Abstract:
The effects of girdling performed at various dates were evaluated during two consecutive years in high- and low-bearing commercial orchards of 'Fortune' mandarin and 'Clausellina' Satsuma mandarin. The time-dependent response was evaluated through fruitlet abscission, final fruit-set and yield as related to carbohydrate contents in developing fruitlets. A few days after treatment, girdling increased the soluble sugars content (SSC) in fruitlets, reduced the daily fruit drop, and thereby diminished abscission. Application of girdling to low-bearing 'Fortune' mandarin orchards was most effective 15 d before anthesis (DBA) and 35 d after anthesis (DAA). It increased yield by 125%. In high-bearing orchards, the best results were achieved by girdling 35 DAA, which increased yield by 28%. In both orchards, the effect of girdling declined gradually from 35 DAA to the end of fruit drop. SSC values were found to be positively correlated with fruit-set at 25 DAA, but this tendency was reversed by 50 DAA. This study showed that the effects of girdling are time-dependent, and that yield can be improved in cultivars of different parthenocarpic ability.

Girdling increases carbohydrate availability and fruit-set in citrus cultivars irrespective of parthenocarpic ability
The effects of girdling performed at various dates were evaluated during two consecutive years in high- and low-bearing commercial orchards of 'Fortune' mandarin and 'Clausellina' Satsuma mandarin.
