Mean (± SEM) leaf nitrogen (N) and carbon (C) total content and concentration, and C : N ratio of Zea mays leaves from arbuscular mycorrhizal fungi (AMF) and nonAMF treatments in Expt 1  (n = 12)

		AMF	NonAMF
Leaf N	Total content (mg)	13.8 ± 0.8 a	10.2 ± 0.9 b
	Concentration (mg g−1 DW)	11.3 ± 0.6 f	8.8 ± 0.5 g
Leaf C	Total content (mg)	503.2 ± 19.9 j	488.1 ± 27.2 j
	Concentration (mg g−1 DW)	413.4 ± 2.8 m	422.9 ± 3.7 n
	Leaf C : N ratio	37.6 ± 2.0 x	50.0 ± 3.0 y

Different letters within rows represent significant differences at P = 0.05 (in bold) as determined using two‐way ANOVAs.
