FIG. 6.

Comparison of the abilities of S. enterica (S.e.) strains to grow on germinating alfalfa seeds. Alfalfa seeds were inoculated with the indicated strain of S. enterica, and populations (Pop) were monitored as described in the legend to Fig. 1. Mean populations at 24 h (open bars, populations after exponential growth) and 48 h (diamond-filled bars, maximum populations) are shown. Error bars represent the standard deviations. The experiment was repeated at least three times, with similar results.
