Abstract/Contents: | "Endophyte infection of many grasses results in enhanced resistance to pre-emergence damping-off pathogens. To determine if antifungal compounds are produced in germinating seed, tall fescue (Festuca arundinacea cv Pixie) seed lots with endophyte (Acremonium coenophialum) infestation levels of 79% (EH) and 29% (EL) were compared. Seeds (5G) were scarified, surface sterilized then allowed to imbibe water (50 ml). Water was decanted and mixed 2:1 with 3% agar (imbibition agar). Seeds were ground in buffer, then mixed with 2% water agar (macerate agar). Culture plates (6-well) were used to pair EH and EL treatments. Cores (5 mm) of Rhizoctonia solani and Pythium aphanidermatum were transferred to media. Diameter of colonies was measured. The experiment was performed three times. Data were analyzed with a paired t-test. Growth of R. solani was significantly greater on EL macerate agar than on EH macerate agar at 72 h but not at 48 h or 96 h. Growth was greater on EL imbibition agar only at 48 h. Growth of P. aphanidermatum was significantly greater on EL imbibition agar only at 48 h. Growth of P. aphanidermatum on macerate agar was not affected by endophyte status. |
