Effects of arbuscular mycorrhizal fungi (AMF) inoculation on the root and NADP-dehydrogenase activity of tomato seedlings. a The root activity of NM and AM seedlings at 40 d. b The activity of NADP-ME in roots of NM and AM seedlings. c The activity of NADP-ICDH in roots of NM and AM seedlings. d The activity of G6PDH in roots of NM and AM seedlings. e The activity of 6PGDH in roots of NM and AM seedlings. The results represent the means ± SE. Three independent experiments were performed, with similar results. * represent significant difference. NM, tomato seedlings cultivated in continuous cropping substrate. AM, tomato seedlings cultivated in continuous cropping substrate inoculation with AMF
