Abstract
SummaryThe role of ethylene in mango (Mangifera indica L.) fruitlet abscission was investigated by determining endogenous ethylene concentrations in intact and about-to-abscise fruitlets and their pedicels, and the effects of exogenous applications of ethephon and inhibitors of ethylene biosynthesis. About-to-abscise fruitlets and pedicels at pinhead, pea and marble stages had higher endogenous ethylene production than intact tissues in ‘Kensington Pride’ and ‘Glen’ (191% and 66% more ethylene in ‘Kensington Pride’ in 2001, 53.5% and 101% in ‘Glen’ in 2000, and 135% and 93% in 2001). Exogenous application of ethephon at fruit set, accelerated fruitlet abscission compared with control. Fruitlet abscission was increased with increased rates of ethephon applied during 1999 and 2000. Exogenous spray of ethylene inhibitors at pre-anthesis stage increased fruitlet retention. Spray of STS or CoSO4 (200.mg l–1) resulted in the highest fruitlet retention (7.7 and 7.6 fruit per panicle) compared with control (4.9 fruit per panicle). These results suggested that ethylene is involved in mango fruitlet abscission.
