Figure 2. Effect of (E,E)-2,4-heptadienal on M. oryzae. Assay of the antifungal activity of volatile compounds was performed according to Taniguchi et al.²⁵ Rate of spore germination after treatment with (E,E)-2,4-heptadienal and linalool for 6 h is indicated. Values are the means ± SE of 4 independent experiments (n = 100 spores per one experiment). Asterisks represent statistically significant difference from a mock-treated control at P < 0.05 (the Student t-test).
