Title
The effect of magnesium ions on the vesicular—arbuscular mycorrhizal infection of maize roots
M. GRYNDLER; H. VEJSADOVÁ; V. VANČURA New Phytologist 1992. doi:10.1111/j.1469-8137.1992.tb00073.x
Other claims from this paper (7)
- Observation Mycorrhizal infection was highest at nutrient-solution MgSO 4 concentrations of 5 84–11.68 mmol 1 −1.
- Intervention effect Increased magnesium concentration stimulated maize root colonization.
- Intervention effect Increased calcium concentration did not stimulate maize root colonization.
- Intervention effect Increased potassium concentration did not stimulate maize root colonization.
- Intervention effect Replacing magnesium chloride with magnesium sulphate produced no significant difference in infected maize root length.
- Intervention effect Across a broad range of magnesium sulphate concentrations, maize biomass did not differ significantly.
- Mechanism The authors found that changes in nutrient-solution pH or osmotic pressure could not explain magnesium stimulation of maize root colonization.
