Flavanoid biosynthesis down after growth induction?

To all the physiologist types out there (or anyone else with a clue): I
have recently completed a microarray analysis of release from
para-dormancy (apical dominance) in underground adventitious buds of
leafy spurge. Although there were only about 1200 genes on the chip, I
was able to detect a significant down regulation for a number of genes
involved in flavanoid biosynthesis upon growth induction. Does anyone
have a clue as to why flavanoids would be detrimental (or negatively
responsive) to growth ?  Any thoughts would be welcome.
