From: Factors influencing the production of stilbenes by the knotweed, Reynoutria × bohemica
Mycorrhizal colonization F% of Reynoutria × bohemica roots grown with melilot (a - left) and aboveground biomass of Melilotus alba (b - right), in pots with various substrates based on miocene clay from coalmine spoil banks in 2006 and 2007. ClayC = clay enriched with slow-release biofertilizer Conavit; ClayCS = clay enriched with Conavit and arbuscular-mycorrhizal product Symbivit, both produced by Symbiom Ltd. Equal letters within the same year indicate non-significant differences between the substrates.
