Root-Differentiating Properties of Some Glycosides and Polycyclic Phenolic Compounds Found in Apple and Pear Fruitst

摘要: SummaryProcesses of oxidation, mediated by phenolase or aeration, were found to be effective pathways in the production root-differentiating substances from some glycosidic and polycylic phenols. Moderately precursors phloridzin, arbutin, quercitrin, chlorogenic acid; phloretin quercetin highly effective.The growth-regulating action phloridzin its sub-products, phloretin, phloretic, p-hydroxybenzoic acids was reviewed, considered with new information on root-promoting properties oxidized sub-products. It is suggested that principal function Malus provide tree a large varied supply substances.
