Prohexadione-Ca treatments lead to alternations in the phenylpropanoid metabolism of grapevine and strawberry. Both crops accumulated unusual flavonoids after prohexadione-Ca treatment, which were identified as derivates of eriodictyol und luteoliflavan. Pentahydroxyflavnanone derivates were identified only in treated grapevine tissues.
Concentrations of constitutive phenylpropanoids were also affected by the prohexadione-Ca treatment. Therefore, decreases of hydroxycinnamic acids and flavonol... »
