HASIL DAN PEMBAHASAN Mikoriza pada Sampel Tanah ,Numerous vesicles (or spores) often form near entry points along with the arbuscule-hyphal network. Spores often form as dense clusters within roots, but also are patchily distributed singly or in clusters of only a few spores. There is a higher proportion of irregularly-shaped spores than observed with R. intraradices. Some isolates in INVAM are consistently white, but the spores are at the small end of the size distribution, others are highly variable in color (changing with pot culture generation), and still others are mostly yellow to yellow-brown. This continuum eliminates any morphological distinction between R. clarus and Rhizophagus manihotis. Apr 9, 2020 · The spores were then washed into a filter paper for vacuum filtration.
