Reduction of A. tumefaciens and A. rhizogenes colony forming units after 0, 6, 12 and 24 h of their inoculation into HP cells. To estimate the number of viable bacterial cells, HP culture was diluted until 10⁻⁶ and 100 μl (which contains approximately 250 bacterial cells) was spread on culture plates and incubated in dark at 28°C
