a
Within a column, means with same letter are not significantly different based on Fisher's protected LSD (P = 0.05). ND, not determined.
b
Inhibition expressed as a percentage of the reduction of mycelial dry weight of 3-day-old liquid cultures in the presence of CHDA (0.15 mg/ml) relative to the untreated control.
c
Inhibition expressed as a percentage of the reduction of conidial germination following a 24-h incubation period with CHDA (0.15 mg/ml) relative to the untreated control.
d
Within a column, means with same letter are not significantly different based on Fisher's protected LSD (P = 0.01).
e
Δ/mol = [% 18:1 + 2(% 18:2) + 3(% 18:3)]/100.
