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 stu...

Root-knot nematode penetration and morphopathlogy of the infection sites were studied in roots, stem and hypocotyls of Luffa cylindrica, L. and effect of combined inoculation of Vesicular Arbuscular Mycorrhizae (VAM) fungi included Glomus mossae, Glomus intraradices, G. fasciculatum, Acaulospora sp. and Meloidogyne incognita (Root-knot Nematode) were investigated. The maximum number and size of...

The influence of different initial inoculum densities of the root-knot nematode Meloidogyne javanica on the growth of sage (Salvia officinalis), root-knot development and nematode multiplication was investigated 90 days after inoculation under greenhouse conditions. With the increase in the nematode initial inoculum densities, shoot fresh/dry weight, shoot/root length and root fresh/dry weight ...

The interaction among Glomus intraradices, Meloidogyne incognita, and cantaloupe was studied at three soil phosphorus (P) levels in a greenhouse. All plants grew poorly in soil not amended with P, regardless of mycorrhizal or nematode status. In soil amended with 50 mug P /g soil, M. incognita suppressed the growth of nonmycorrhizal plants by 84%. In contrast, growth of mycorrhizal plants inocu...

abstract in this study the effect of combination of trichoderma harzianum bi and salicylic acid were studied on root knot nematode (meloidogyne javanica) disease on tomato under green house conditions. the roots of tomato seedlings at six-leaf stage were inoculated with suspensions of fungal antagonist (106 conidia/ ml), 5mm salicylic acid and 2000 second-stage juvenile (j2). combined applicati...

the influence of different initial inoculum densities of the root-knot nematode meloidogyne javanica on the growth of sage (salvia officinalis), root-knot development and nematode multiplication was investigated 90 days after inoculation under greenhouse conditions. with the increase in the nematode initial inoculum densities, shoot fresh/dry weight, shoot/root length and root fresh/dry weight ...

two fungal species glomus mosseae and glomus intraradices as well as meloidogyne javanica nematode were used in order to evaluate the effects of arbuscular mycorrhizal fungi on control of different populations of root-knot nematode in tomato. a greenhouse test was established as factorial experiment based on completely randomized design with 8 treatments and 4 replicates followed by mycorrhizal...
