Pre-inoculation with arbuscular mycorrhizal fungi suppresses root knot nematode (Meloidogyne incognita) on cucumber (Cucumis sativus)

Abstract

A pot experiment was conducted to evaluate the influence of pre-inoculation of cucumber plants with each of the three arbuscular mycorrhizal (AM) fungi Glomus intraradices, Glomus mosseae, and Glomus versiforme on reproduction of the root knot nematode Meloidogyne incognita. All three AM fungi tested significantly reduced the root galling index, which is the percentage of total roots forming galls. Numbers of galls per root system were significantly reduced only in the G. intraradices +M. incognita treatment. The number of eggs per root system was significantly decreased by AM fungus inoculation, no significant difference among the three AM fungal isolates. AM inoculation substantially decreased the number of females, the number of eggs g −1 root and of the number of eggs per egg mass. The number of egg masses g −1 root was greatly reduced by inoculation with G. mosseae or G.versiforme. By considering plant growth, nutrient uptake, and the suppression of M. incognita together, G. mosseae and G. versiforme were more effective than G. intraradices.

Rhizosphere interactions between earthworms (Eisenia fetida) and arbuscular mycorrhizal fungus (Funneliformis mosseae) promote utilization efficiency of phytate phosphorus in maize

“…At the same time, eight earthworms with similar weights (3.40 AE 0.03 g) were added to the appropriate pots. Each kilogram of the OECD soil was fertilized with a mineral solution containing 50 mg P in C 6 H1 8 O 24 P 6 (organic P), 200 mg N (NH 4 NO 3 ), 200 mg K (K 2 SO 4 ), 100 mg (MgSO 4 Á7H 2 O), 5 mg Zn (ZnSO 4 Á7H 2 O), 5 mg Mn (MnSO 4 Á7H 2 O), and 5 mg Cu (CuSO 4 Á5H 2 O) (Zhang et al, 2008).…”

Growth and Yield Response of Watermelon to in-row Plant Spacings and Mycorrhiza

“…and other AM fungi is often observed (Smith and Read, 2008). Glomus mosseae is often used in cucumber production in the presence of soil born diseases as well as under drought stress or low P availability (Chandanie et al, 2006;Zhang et al, 2008). However, significant positive effects on the watermelon biomass and yield have been observed following inoculation with G. clarum in the presence and absence of drought stress conditions (Kaya et al, 2003).…”

Interactive impacts of earthworms (Eisenia fetida) and arbuscular mycorrhizal fungi (Funneliformis mosseae) on the bioavailability of calcium phosphates

“…To keep growth normal, plants were watered every third day, and each kilogram of OECD soil was fertilized with a modified Hoagland's nutrient solution containing the following: 50 mg P in CaHPO 4 •2H 2 O form (Ca-P), 200 mg N (NH 4 NO 3 ), 200 mg K (K 2 SO 4 ), 100 mg (MgSO 4 •7H 2 O), 5 mg Zn (ZnSO 4 •7H 2 O), 5 mg Mn (MnSO 4 •7H 2 O), and 5 mg Cu (CuSO 4 •5H 2 O) (Zhang et al 2008). There were four treatments: CK is the soil without earthworm and AM fungi additions; E is the soil with earthworm addition; AM is the soil with AM fungi addition; and E+AM is the soil with both earthworm and AM fungi additions.…”
