Figure 5From: Effect of clone selection, nitrogen supply, leaf damage and mycorrhizal fungi on stilbene and emodin production in knotweedNitrogen effect on stilbene production in knotweed. Effect of soil N level on the production of stilbenes per plant (± S.E) in the belowground biomass of the control plants of three clones in 2007. FJ = Fallopia japonica, FBM = Fallopia xbohemica from Mošnov, FBP = Fallopia xbohemica from Průhonice. Asterisks indicate significant differences, n = 6.Back to article page
