    Effect of vesicular-arbuscular mycorrhiza on survival, penetration and development of root-knot nematode in tomato (1985)
    Springer
    Plant and soil 87 (1985), S. 305-308 
    Details
    ISSN: 1573-5036
    Keywords: Root knot nematode ; Tomato ; VA mycorrhiza

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Effect of mycorrhizal colonisation byGlomus fasciculatum on survival, penetration and development of the root knot nematodeMeloidogyne incognita in tomato was studied. The number of giant cells formed in mycorrhizal plants was significantly low. Mycorrhizal roots did not prevent the penetration by nematode larvae. Root extract from the mycorrhizal plants brought about 50% mortality of the nematode larvae in four days time.

    Possible influence of Rhizobium on VA mycorrhiza metabolic activity in double symbiosis of alfalfa plants (Medicago sativa L.) grown in a pot experiment (1988)
    Springer
    Biology and fertility of soils 6 (1988), S. 65-67

    ISSN: 1432-0789
    Keywords: Rhizobium mefloti ; Glomus fasciculatus ; Medicago sativa ; Succinate dehydrogenase ; Acetylene reduction assay (ARA) ; VA mycorrhiza ; Alfalfa

    Notes: Summary Alfalfa (Medicago sativa, L. cv Aragón) plants were grown under greenhouse conditions in pots of inert sand and vermiculite. The plants were inoculated with Rhizobium meliloti strain 102F28, with Glomus fasciculatus or with a mixture of both microorganisms. Plants inoculated with both Rhizobium and Glomus had the highest shoot dry weight and the lowest root-to-shoot ratio. Roots from dually inoculated plants also had a higher oxygen uptake and nodule nitrogenase activity than those from plants inoculated with either of the two microsymbionts alone. However, the dry weight of the roots from only VAM-infected plants was higher than those from Rhizobium or from Rhizobium plus Glomus-inoculated ones. These differences did not correlate with succinate dehydrogenase activity, which was similar between treatments. Nutrient element concentrations were increased in dually infected plants in comparison with those of plants inoculated with only Rhizobium or Glomus. These data suggest that Rhizobium may affect fungal metabolism and that the effect is not achieved via the tricarboxylic acid pathway.

    Intensity of mycorrhizal infection and response of onion at different stages of growth (1981)
    Springer
    Plant and soil 63 (1981), S. 295-298 
    Details
    ISSN: 1573-5036
    Keywords: Glomus ; Mycorrhizal intensity ; Onion ; VA mycorrhiza
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary A time course experiment was conducted to study the intensity of root infection and the response of onion. Mycorrhizal infection with internal hyphae and arbuscules was observed in onion roots 15 days after sowing and infection percentage progressively increased up to 35 days. Plants inoculated with the mycorrhizal fungus weighed less than non-mycorrhizal plants during initial stages up to 35 days but grew faster later after 38 days.

    Effect of soil volume and plant density on mycorrhizal infection and growth response (1984)
    Springer
    Plant and soil 77 (1984), S. 373-376 
    Details
    ISSN: 1573-5036
    Keywords: Growth response ; Mycorrhizal infection ; Onion ; Root density ; Soil volume ; VA mycorrhiza
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary The effect of soil volume and plant density on mycorrhizal infection and growth response was studied with onion. There was a significant negative correlation between percentage vesicular-arbuscular mycorrhizal infection and root density. The growth response due to mycorrhiza decreased when less soil was available for the plant. The root: shoot ratio decreased with increasing plant density in both mycorrhizal and non-mycorrhizal plants. Pot size did not affect the root: shoot ratio.

    Dual inoculation with VA mycorrhiza and Rhizobium is beneficial to Leucaena (1984)
    Springer
    Plant and soil 78 (1984), S. 445-448 
    Details
    ISSN: 1573-5036
    Keywords: Leucaena ; Rhizobium ; VA mycorrhiza

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Response ofLeucanea leucocephala to inoculation withGlomus fasciculatum and/or Rhizobium was studied in a phosphorus deficient unsterile soil.G. fasciculatum only inoculation improved nodulation by native rhizobia and Rhizobium only treatment improved colonization of roots by native mycorrhizal fungi. Dual inoculation with both the organisms improved nodulation, mycorrhizal colonization, dry weight, nitrogen and phosphorus content of the plants compared to single inoculation with either organism.

    Effect of fungicides on mycorrhizal colonization and growth of onion (1984)
    Springer
    Plant and soil 80 (1984), S. 147-150 
    Details
    ISSN: 1573-5036
    Keywords: Fungicides ; Onion ; VA mycorrhiza
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Effect of five fungicidesviz Agrosan. Benlate, Captan, Ceresan and Plantavax on VA mycorrhizal symbiosis in onion was studied in a phosphorus deficient, sandy loam soil. Two levels of fungicides (2.5 μg and 25 μg/g soil) were applied to the soil. Agrosan, Benlate and Plantavax applied at 25 μg/g soil reduced the mycorrhizal colonization significantly. All the fungicides, except Captan, applied at lower concentration reduced plant growth and P uptake. Captan applied at the lower concentration had no effect on mycorrhizal colonization, plant growth and P uptake, and when applied at higher concentration had least effect on plant growth compared to other fungicides.
