    Figure 3.

    The effect of irrigation on rooting density (mm root length/cm3 soil volume) of VAM inoculated (M) or noninoculated (N) Argentine mesquite, 60 cm from the trunk at depths of 0 to 140 cm below ground surface, A) 6 and B) 12 months (June and December, 1992, respectively) after transplanting into a simulated landscape (n = 12). Statistical probabilities shown above are for the interaction of irrigation and mycorrhizal treatments. W = drip irrigated regularly; D = dry.

    The effect of irrigation on specific root length density (mm root length/g fresh root weight/cm3 soil volume) of VAM inoculated (M) or noninoculated (N) Argentine mesquite, 60 cm from the trunk at depths of 0 to 140 cm below ground surface, A) 6 and B) 12 months (June and December, 1992, respectively) after transplanting into a simulated landscape (n = 12). Statistical probabilities shown above are for the interaction of irrigation and mycorrhizal treatments. W = drip irrigated regularly; D = dry.
