Abstract:In this study, antibacterial activities of different concentration (20, 10, 5, 2.5 and 1%) of sığla, Liquidambar orientalis Mill. var. orientalis, storax oil were investigated in vitro against 13 economically important plant pathogenic bacteria. 20% concentration of sığla storax was the most effective antibacterial dose. The oil showed a significant antibacterial effect to Xanthomonas axonopodis pv. vesicatoria (Xav), Pseudomonas syringae pv. tomato (Pst), Rhizobium tumefaciens (Rt), Clavibacter michiganensis subsp. michiganensis (Cmm), Pseudomonas syringae pv. syringae (Pss), Pseudomonas corrugata (Pc), Rhizobium vitis (Rv), Erwinia amylovora (Ea) and Xanthomonas campestris pv. campestris (Xcc), respectively. The antibacterial effect of sığla storax was lowest against Ralstonia solanacearum (Rs), Pseudomonas savastanoi pv. savastanoi (Pssav.), Pseudomonas syringae pv. phaseolicola (Psp) and Pectobacterium carotovorum pv. carotovorum (Pcc) comparing those of Thymbra spicata var. spicata essential oil (100 µg/ml) and Streptomycin (100 µg/ml). Seed treatment of tomato with sığla storax (5-20%) oil completely inhibited the growth of Cmm, Pst, and Xav both in vitro and in vivo assays. Treatment of tomato seeds with sığla storax had no effect on seed germination. These results indicate that sığla storax may be a natural seed protectant for seed-borne bacterial pathogens of tomato. This is the first report on antibacterial effect of sığla storax against plant pathogenic bacteria.
