Potential enzymatic activities were expressed as μmol h–1g–1 root. * shows significant effects among enzyme activities (p < 0.01). Different letters show significant differences between C availabilities (p < 0.05). Values Results are the mean of 10 determination per replicate (n = 3) ± SD. β-gluco, β-glucosidase; β-xilo, β-xylosidase; β-glucu, β-glucuronidase; CeloBio, celobiohydrolase; N-acetyl, N-acetylglucosaminidase; Leu, leucine aminopeptidase; and AP, acid phosphatase.
