Kentucky 31 tall fescue

Extract of Kentucky 31 tall fescue was prepared by soaking 75 g fresh fescue leaves for 24 hours in 500 ml of distilled water. The extract was filtered and fractionated through cation and anion exchange columns according to the procedure described by Williams (6), Boland (7 ) and Boland and Garner (8). The extract was first...

Finally, there also may be an interaction of plant compounds with other endophyte-specific compounds that serve as effective nematode-deterring or toxic substances. For example, foliar chitinase is considered to play a role in nematode resistance (Roberts et al., 1992). Other examples include the work of Breen (1994). When M. marylandi was inoculated in soil, foliar chitinase activity was 10 times higher in the treatment groups than in controls. Further, in Kentucky 31 tall fescue clones, chitinase activity is high in resistant clones and low in susceptible ones. In this same experiment, Johnstone, a cultivar known for its lack of field persistence, showed low levels of chitinase and did not survive the... 

Plants of Kentucky tall fescue were dug from the field in July, and the soil was washed from the roots. Tops and roots were separated...
