| Abstract/Contents: | "Germination, growth, and sporulation of Gloeotinia temulenta on PDA increased from 5 through 20 C, then declined. No germination of growth was observed at 30 C. Radial growth on PDA amended with NaCL, KCL or sucrose declined with decreasing water potentials through -9 to -10 MPa. Spore production on sucrose-amended PDA increased through -4 MPa then declined through -10 MPa. No spores were produced on KCl- or NaCL- amended media. Infection of annual ryegrass occurred at 15, 20 and 25 C but not at 30C. A dew period was not required for infection when a drop of conidial suspension was placed in open flowers of annual ryegrass or when a conidia-laden exudate from infected seed was transferred to ovaries in open flowers. Percentage infection increased with increasing inoculum concentration from 10 [to the second power]2 to 10 [to the fourth power]4 conidia/ml. Numbers of conidia on infected seed at 20 C. increased from six through 14 days after inoculation." |
