Abstract/Contents: | "Samples of 39 perennial ryegrass (Lolium perenne L.) and 24 Italian ryegrass (Lolium multiflorum Lam.) commercial seed-lots used at the Grassland Research Institute between 1974 and 1978 were examined for the presence of seed-born Drechslera species. The five species of Dreshclera isolated from the seeds were D. andersenii, D. sicans, D. nobleae, D. sorokiniana and an unidentified Drechslera sp. A high proportion of the seed-lots were infected but levels of infection were low excet in the perennial ryegrass cv. S24. Infection was located more commonly inside the caryopses than externally on the lemmas and paleae, and about 12% of the seedlings growing from infected seeds were infected. The species recovered in the seedlings were the same as those observed on the seeds. There was no relationship between levl of seed infection and level of damage observed in the field in the autumn of the first harvest year." |
