Abstract

Greenhouse studies showed in the transplant of tomato that two weeks before infection with nematodes with two species of mycorrhizal G. mosseae and G. intraradices had been inoculated, were significantly offseted the reduction of growth that had been done by nematodes. It should be noted that the percentage of root colonization with two species 66.3% and 62.2% respectively and based on this study were set completely randomized design with five treatments and five replicates. Dry weight of shoots and roots of inoculated transplant with G. mosseae 44% and 45%, respectively, was higher compared with Nematodes alone (P ≤ 0.05). Dry weight of shoots and roots of inoculated transplant with G. intraradices was more than 40% and 37%. Number of nodes, the diameter of the root-knot nematode penetration in inoculated roots with G. mosseae wasdecreased 55%, 47%, and 55%respectively, compared with Nematodes alone (P ≤ 0.05). Number of nodes, the diameter of the root-knot nematode penetration in inoculated roots with G. intraradices was decreased 47%, 41% and 51% respectively. In treated plants with G1M and G2M, gall index was decreased the 1 unit compared with infection control (P ≤ 0.05). Nematode population in treated soil with each two species mycorrhizal fungus was decreased less than half compared with infection control with nematodes only (P ≤ 0.05).
