Table 1.

Percentage of arbuscular mycorrhizal colonization in roots of maize and tomato plants from experiments 1 and 2

Treatment	Experiment 1		Experiment 2*
	Maize	Tomato	Maize
Control WW	0^b	0^b	0^b
G. intraradices WW	74^a	68^a	63^a
Control DS	0^b	0^b	0^b
G. intraradices DS	73^a	70^a	60^a

Within each column, means followed by different letters are significantly different (P < 0·05) as determined by Duncan's multiple range test. WW, well watered; DS, drought stressed.

* The treatment with sodium azide was applied for 50 min just before measurement of root hydraulic conductivities. Thus, no effect of sodium azide on the percentage of AM root colonization was observed.
