Arbuscular Mycorrhizas: Producing and Applying Arbuscular Mycorrhizal Inoculum

Arbuscular Mycorrhizas Reduce Nitrogen Loss via Leaching

The capacity of mycorrhizal and non-mycorrhizal root systems to reduce nitrate (NO₃⁻) and ammonium (NH₄⁺) loss from soils via leaching was investigated in a microcosm-based study. A mycorrhiza defective tomato mutant and its mycorrhizal wildtype progenitor were used in this experiment in order to avoid the indirect effects of establishing non-mycorrhizal control treatments on soil nitrogen cycl...

THE SYMBIOSIS EFFECT OF VESICULAR-ARBUSCULAR MYCORRHIZA ON GROWTH OF POA BULBOSA (BULBOS BLUE GRASS)

Inoculation experiments were carried out in pot culture to determine the effects of VA fungi on the growth of Poa bulbosa. In this experiment, four treatments  were  used: 1. Strile soil without  inoculation,  2. Strile soil plus inoculum, 3. Natural soil plus inoculum, and 4. Natural soil without inoculation. Inoculum was prepared from a suspension of mycorrhizal  roots of  Poa  plants (Root c...

Effects of phosphorus availability and vesicular–arbuscular mycorrhizas on the carbon budget of common bean (Phaseolus vulgaris)

Low phosphorus availability is often a primary constraint to plant productivity in native soils. Here we test the hypothesis that root carbon costs are a primary limitation to plant growth in low P soils by assessing the effect of P availability and mycorrhizal infection on whole plant C budgets in common bean (Phaseolus vulgaris L.). Plants were grown in solid-phase-buffered silica sand provid...

Update on Symbiosis Carbon Metabolism and Transport in Arbuscular Mycorrhizas

Colonization of the land by plants some 400 million years ago was associated with the colonization of their primitive roots by soil-borne filamentous fungi (Nicolson, 1975; Simon et al., 1993; Taylor et al., 1995). Today, 90% to 95% of land plants still maintain some type of mycorrhizal association so that “mycorrhizas, not roots, are the chief organs of nutrient uptake by land plants” (Smith a...
