---|---|---|---|---|---|---|
1 M | 2 M | 3 M | 4 M | Hydrophobic | Hydrophilic | |

Different concentrations of glycerol (1 to 4 M) to analysis incipient cytorrhysis. At least 100 appressoria were counted for each concentration.
Appressorium formation on hydrophilic or hydrophobic surfaces at 24 hours post incubation; ±SD was calculated from three repeated experiments and asterisk indicates statistically significant differences (Duncan's new multiple range test,
means p<0.01).
