This paper summarises the information on the occurrence of phenolic compounds in apple Malus domestica leaves and fruits with special reference to their developmental changes and regulation of biosynthesis. Besides the ontogenetic variation in biosynthesis and accumulation, the stress-induced and pathogenesis-related changes are emphasised. Aspects of commercial importance are addressed, ranging from fruit colouration, through disease resistance, to the direct use of apple tissues, as raw material for the extraction of bioactive phenolic compounds.     «
