This assay (Moorman and Reeves, 1979) measures the percentage mycorrhizal colonization in an assay host after a limited time period so that only primary infections occur. Sometimes, assays must be conducted at different sample dilutions because the higher the infectivity, the sooner secondary colonization ... Gigasporaceae - Morton & Benny. Species in this family form large (usually >200 um) asexual spores with the following morphological properties: The spore wall consists of a permanent outer layer enclosing a laminate layer, each with different properties that distinguish species (e.g. color, thickness, reaction in Melzer’s reagent, etc.) and.
