From: Factors influencing the production of stilbenes by the knotweed, Reynoutria × bohemica
Relationship between the ratio of resveratrol contained in its aglycons (resveratrol and piceatannol) to its glucosides (astringines, piceid, resveratrolosid), and differences in nitrogen concentration in belowground biomass of Reynoutria × bohemica grown with Melilotus alba (measured values) and without melilot (average per substrate). ClayC = clay enriched with slow-release biofertilizer Conavit; ClayCS = clay enriched with Conavit and arbuscular-mycorrhizal product Symbivit, both produced by Symbiom Ltd.
