Abstract: The regulation of Salicylic acid (SA) on ripening and senescence of‘Starkrimson’apple fruits was investigated by spraying SA. Endogenous SA content peak appeared at the early stage of fruit development but decreased
later. Whereas polygalacturonase (PG) and pectinmethylesterase (PME) ctivities were lower in the fruits sprayed with SA in August seasons before harvest while the effects of 0. 002 mmol·L-1 SA was significant ; Furthermore , SA inhibited the fruit respiratory rate during store stage. The data suggested SA could delay fruit ripening.

Key words: Salicylic acid, Apple fruit, Ripening
