Abstract/Contents:"Seed samples of five forage varieties and three turfgrass varieties were collected and analyzed for seed associated fungi by common blotter test and PDA test. The impact of the isolated fungi on seedling emergence and growth was assessed. This study disclosed that the percentage frequency of fungi (PFF) isolated from the experimental sample ranged from 0 to 70.5%. Thirty-five fungal species were isolated, most of them belonged to Fusarium spp., Alternaria spp., Selminthosporium spp., Sclerotium sp. [spp.], Stemphylium spp., and Aspergillus spp. The PFF of Common (Eremochloa ophiuroides) and Potomac (Dactylis glomerata) seed samples was higher than others. As determined by the PDA test, the PFF of these two varieties was 28.4% and 70.5% respectively for the non-disinfected seed, 40.8% and 28.8% for the disinfected seed. The fungi isolated from their seeds showed insignificant damage to their seedling emergence and growth. The PFF of Santiago (Medicago polymorpha) and Puna (Cichorium intybus) was relatively low. But the fungi isolated from their seeds inoculated by Fusarium spp. and Stemphylium spp. were 44.0% and 21.7% lower respectively than un-inoculated and non-disinfected controls, the corresponding rates of diseased seedling were 22.7% and 29.7%. The rates of seedling emergence of Puna seeds inoculated by Alternaria spp. and Aspergillus spp. were 22.0% and 27.5% lower respectively than those of controls. The corresponding rate of diseased seedling were 2.3% and 29.3%."
