    BOC Sciences β selinene
    Effects of pure volatile organic compounds (VOCs) on downy mildew in air volume. Leaf disks were treated with water (control) or a pure VOC at concentrations of 20.0 mg/L ( A ), 5.0 ( B ) and 0.5 (black) mg/L in air volume, on a filter paper disk without contact with leaf tissues. Five replicates (dishes with five disks each) were assessed for each treatment and the experiment was carried out twice. As the Kruskal-Wallis test indicated no significant differences between the two experiments ( p > 0.05, n = 5 replicates per experiment), data from the two experiments were pooled. The pooled mean and standard error values of ten replicates from the two experiments are presented for each treatment. For each chart, different letters indicate significant differences among treatments according to the Kruskal-Wallis test ( p ≤ 0.05). Cadinene, β-caryophyllene, <t>β-selinene</t> and ledol (20.0 mg/L in air volume) did not affect downy mildew severity as compared with the control disks (Kruskal-Wallis test p > 0.05) and severity data are therefore not shown here. Asterisks indicate phytotoxic effects on leaf disks.

    Article Snippet: Pure VOCs were selected according to the SPME/GC-MS results, such as Benzenethanol, β-caryophyllene, trans-2-pentenal, 2-ethylfuran and β-cyclocitral (Sigma-Aldrich); cadinene (a mixture of ɣ-cadinene and δ-cadinene; (BOC Sciences); β-selinene and ledol (Xiamen Freede Industry).
