GRSP content and hyphae length in rhizosphere of <i>R</i>. <i>pseudoacacia</i> colonized by <i>R</i>. <i>irregularis</i> (RI), <i>G</i>. <i>versiforme</i> (GV) or not (CV).

<p>Significant differences are indicated by different letters (one-way ANOVA with Fisher’s LSD; <i>P</i> = 0.05; n = 6). EE-GRSP, easily extractable glomalin-related soil protein; T-GRSP, total glomalin-related soil protein; HL, hyphae length.
