This would reduce the
glucose supply from the starch via the amylolytic pathway,
influencing respiration and growth. In our work, ferulic and pcoumaric
acid induced very similar effects in O. crenata radicle
growth. The exogenous applications of ferulic and p-coumaric
acid to pea plants caused growth inhibition, carbohydrate and
quinate accumulation in leaves, and induction of ethanolic
fermentation, effects that are similar to those physiological
effects after herbicides that inhibit branched chain amino acid
biosynthesis. Ferulic and p-coumaric acids could play a role in
the mode of action of these herbicides
