über die Beziehungen zwischen flavonolaufbauenden Enzymen, einem flavonolumwandelnden Enzym und der Akkumulation phenylpropanoider Verbindungen während der Antherenentwicklung

摘要

The difference in activity of enzymes which are involved in the biosynthesis of flavonols (phenylalanineammonium-lyase, chalcone-flavanone isomerase) and of an enzyme which converts flavonols is studied during the development of anthers inTulipacv. Apeldoorn. The results are considered in relation to the accumulation of simple phenylpropanes, of an intermediate a chalcone and of different flavonoid compounds.
