Figures & data
Figure 1. Effect of aluminum on the growth (bar) and Al content (line) in the mycelium of Paxillus involutus. The values are the means±standard error of means (n=3).
Figure 2. Shoot height, shoot and root biomass of mycorrhizal and non-mycorrhizal P. deltoides plants grown under different aluminum concentrations. Mean of six replicates±SEM. (Al: significant between Al concentration, EcM: significant between mycorrhizal and non-mycorrhizal plants; Al×EcM: interaction, *p<0.05, **p<0.01, ***p<0.001; n.s, not significant. Empty bars: non-mycorrhizal; filled bars: mycorrhizal plants).
Figure 3. Concentrations of Al, Ca, Mg and P in shoots of mycorrhizal and non-mycorrhizal P. deltoides plants grown under different aluminum concentrations. Mean of six replicates±SEM. (Al: significant between Al concentration, EcM: significant between mycorrhizal and non-mycorrhizal plants; Al×EcM: interaction, *p<0.05, **p<0.01, ***p<0.001; n.s, not significant. Empty bars: non-mycorrhizal; filled bars: mycorrhizal plants).
Figure 4. Oxalic acid exudation in non-mycorrhizal (empty bars) and mycorrhizal (filled bars) plants in response to Al. Mean of six replicates±SEM. (Al: significant between Al concentration, EcM: significant between mycorrhizal and non-mycorrhizal plants; Al×EcM: interaction, *p<0.05, **p<0.01, ***p<0.001; n.s, not significant).
