Effects of an arbuscular mycorrhizal fungus (AMF), Funneliformis mosseae, on plant growth performance of trifoliate orange (Poncirus trifoliata) seedlings exposed to well-watered (WW) and drought stress (DS).

Treatments	Root mycorrhizal colonization (%)	Plant height (cm)	Stem diameter (mm)	Leaf number (#/plant)	Biomass (g FW/plant)
					Shoot	Root
WW − AMF	0c	25.1 ± 1.2c	4.28 ± 0.15b	23 ± 2c	1.93 ± 0.06c	1.96 ± 0.13c
WW + AMF	61.4 ± 1.1a	45.9 ± 0.6a	5.23 ± 0.29a	32 ± 1a	4.55 ± 0.14a	3.06 ± 0.21a
DS − AMF	0c	17.9 ± 1.6d	3.45 ± 0.19c	19 ± 1d	1.30 ± 0.03d	1.67 ± 0.09d
DS + AMF	55.6 ± 1.2b	39.5 ± 2.5b	4.40 ± 0.22b	29 ± 2b	3.64 ± 0.12b	2.61 ± 0.09b

Data (means ± SD, n = 4) followed by different letters in the column indicate significant differences (P < 0.05) between treatments.
