| Abstract/Contents: | "Leaves, crowns, and roots of 'Merion' Kentucky bluegrass from field infection centers of Fusarium blight were examined histologically. Similar specimens were cultured for Fusaria. F. roseum 'Acuminatum' comprised 56% of the Fusaria isolated, F. roseum 'Crookwell' 26%, and F. roseum 'Equiseti' 18%. Specimens from the 'frog-eye', dead ring, and periphery of the dead ring exhibited varying degrees of vascular plugging in roots and crowns. A coarse, septate mycelium atypical of Fusarium was noted in the cortex of the crowns and in the cortex, endodermis, pericycle, and exylem vessels of roots from the 'frog-eye' and dead ring. The fungus was most prevalent in specimens from the dead ring and was never found in crowns from symptomless grass. The Fusarium cultivars isolated were inoculated into hydroponically-grown, seedling 'Merion' Kentucky bluegrass. Histological study showed that these fungi colonized the cortex of the root exclusively, frequently growing in a digitate manner. Following cortical colonization, they often sporulated externally." |
