Table 2.
Results of orthogonal contrasts for photosynthetic rate, biomass, and nutrient content of Caragana species among inoculated or un-inoculated and inoculated with home AMF (home) or other inocula (away). ‘+/−’ means a positive/negative effect of AMF inoculation or home advantage of conspecific inocula. Statistically significant effects (P) were shown behind.
