FIG. 6.
Culturable population sizes of P. syringae pv. syringae strain B728a among different leaf segments cut from an individual bean leaf, 0, 2, and 8 days after inoculation. Bacteria were removed from individual 44-mm2 segments at each harvest time. The variance/mean ratios for populations on different segments collected 0, 2, and 8 days after inoculation with P. syringae were 971, 104,434, and 157,812, respectively.
