Abstract : Fruitlet abscission is a severe problem in mango (Mangifera indica) production; especially in the mountainous area of north Vietnam where hot and dry winds during long periods of drought cause severe premature fruit loss. Low rates of leaf net photosynthesis of averagely 8 µmol CO2/m2*s are typical for drought stressed mango trees. Presumably due to the declined carbon assimilation, fewer carbohydrates are available for fruit growth and development. Such stress can induce the fruit abscission process that involves an ethylene dependent signal cascade, including the examined ethylene receptors MiETR-1 and Mi
