FIG. 3.

Effects of P. syringae pv. ciccaronei NCPPB2355 bacteriocin preparations (cs, cb, and fIV) at different concentrations (2,000, 6,000, and 12,000 AU ml⁻¹), Kocide 101 (k) (0.3%), and SDW (w) on V-shaped slits (A) and leaf scars (B) of olive plants 30 days after inoculation with P. syringae subsp. savastanoi strain PVBa229. The effect was expressed as the percentage of inhibition of knot weight obtained for inoculated sites treated with bacteriocin preparations or Kocide 101 with respect to the knot weight of untreated inoculated wounds. Percentages of inhibition are for three independent experiments with two replicates each. Standard errors, calculated at a confidence level of 95% (n = 18), are reported in Results.
