Fig 2. Cultivable rhizobacteria of Lucerne roots (CFUs g^-1 root) developed on all tested culture media.

A, ANOVA analysis (2-way interactions) of CFUs numbers of Lucerne rhizobacteria as affected by culture media and incubation period. NA, nutrient agar; LP1g, teabags of Lucerne powder 1.0 g l^-1; LP4g, teabags of Lucerne powder 4.0 g l^-1. B, Morphology of CFUs developed on agar plates of culture media prepared from teabags-only-containing Lucerne powder (4.0 g l^-1 and 1.0 g l^-1 culture media) as well as nutrient agar, inoculated with aliquots of 200 μl of the same root suspension (10⁻⁴): B1, confined/limited and transparent/translucent colonies on LP1.0 g l^-1; B2, numerous slimy colonies on LP4.0 g l^-1; B3, large tinted colonies on NA.
