摘要：

Anthocyanin synthesis occurred early during the culture cycle of grape cell suspensions. Dihydroflavonol reductase (DFR) activity and anthocyanin synthesis were found well correlated within this period. Phosphate deprivation leads to a large enhancement in DFR activity with a maximum which was observed earlier than in control medium. An increase in anthocyanin accumulation was also observed in association with a higher degree of peonidin 3-glucoside acylation.
