| Abstract/Contents: | "Turfgrass anthracnose, caused by Colletotrichum cereale, is a devastating disease on annual bluegrass (AB) and creeping bentgrass (CRB). Intensified putting green management has increased both incidence and severity of the disease worldwide, yet the biology of the pathosystem remains unclear. An experiment was designed to investigate the effects of temperature on C. cereale appressorial formation on two different hosts. Either intact plant or detatched three-week-old leaves of AB or CRB were inoculated with a conidial suspension (2.5*106 conidia/ml) of C. cereale. Inoculated leaves were incubated in dark growth chambers set at one of the following temperatures: 12 C, 18 C, 22 C, 26 C, 30 C and 34 C with high relative humidity (>95%). Twenty-five arbitrarily selected conidia were examined microscopically for appressorial production at different time points after inoculation. Appressoria were observed in each temperature treatment, but developed most rapidly between 22 C and 26 C. Appressorial occurrence was significantly hindered at 30 C and 34 C when compared to the other temperature treatments. The development on intact plant and detached leaves showed a similar pattern while a twelve-hour delay was seen on live plant. These results suggested that C. cereale may infect AB and CRB well prior to the onset of symptoms and defense activities are generated by intact host against fungal invasion." |
