Values of the seven enzymatic activities successively measured on one root tip of the different poplar cuttings (40 clones, eight replicates per clone) either colonized (a) or non-colonized (b) by L. bicolor. No laccase activity was detected on non-mycorrhizal root tips. Genotypes are ranked by mean activity. Enzyme activities are expressed as pmol mm−2 min−1 (Courty et al., 2005). Bars represent the SE (n=8). Grey corresponds to Populus trichocarpa (male) and black to Populus deltoides (female).
