Figure 7From: Effect of clone selection, nitrogen supply, leaf damage and mycorrhizal fungi on stilbene and emodin production in knotweedEffect of mycorrhizal inoculation on nitrogen content in knotweed rhizomes. Effect of mycorrhizal inoculation on the N content (± S.E) in the belowground biomass of four clones at the higher (top) and lower (bottom) soil N levels. Only plants without exposure to leaf damage in 2007 are shown. FJ = Fallopia japonica, FBM = Fallopia xbohemica from Mošnov, FBP = Fallopia xbohemica from Průhonice, FS = Fallopia sachalinensis. Asterisks indicate significant differences, n = 6.Back to article page
