Abstract:

Content of anthocyanin and the activities of enzymes in anthocyanin biosyntheses including plenylalanine ammonialyase (PAL)， chalcone ismoerase (CHI)， dihydroflavonol reductase (DFR) and UDP glucose-flavonoid-3-O-glycosyltranfe-rase(UFGT) were investigated in Acer × freemanii ‘Autumn Blaze’ and Acer rubrum `Brandywine' during the leaf color-changing period. The results indicated that the changes of anthocyanin content exhibited a single peak curve in the two American maple leaves， and the peak appeared at the twentith and twenty-fifth， respectively. The activity of PAL， DFR and UFGT was quadratically correlated with the content of anthocyanin， while CHI activity was significantly and positively correlated with the content of anthocyanin. PAL， CHI and UFGT were the key enzymes in anthocyanin synthesis in ‘Autumn Blaze’ leaves. CHI and UFGT were the key enzyme in anthocyanin synthesisin ‘Brandywine’ leaves.

Key words: Acer, anthocyanin, PAL, CHI, DFR, UFGT
