Název v původním jazyce

Effect of clone selection, nitrogen supply, leaf damage and mycorrhizal fungi on stilbene and emodin production in knotweed

Popis výsledku v původním jazyce

Two-year pot experiment with F. japonica, F. sachalinensis and two F. xbohemica clones.The fast-spreading hybrid clones store less nitrogen in their rhizomes than the parental species. The highest concentrations of stilbenes were found in the rhizomes ofF. japonica. However, because of the high belowground biomass of one clone of F. xbohemica, this hybrid produced more stilbenes per plant than F. japonica. Leaf damage increased the resveratrol and emodin contents in the rhizomes of the non-inoculated knotweed plants. Although knotweed is supposed to be a nonmycorrhizal species, inoculation with mycorrhizal fungi resulted in up to 2% root colonisation. Both leaf damage and inoculation with mycorrhizal fungi (only in the absence of leaf damage) elicitedan increase of the piceid content in the rhizomes of F. japonica. Because the leaf damage suppressed the effect of the root fungi, the effect of leaf damage prevailed over the effect of the mycorrhizal fungi on the piceid content.
