Physiological parameters. Chlorophyll a (A) and chlorophyll b (B) in randomly selected leaves of Calicotome villosa in response to inoculation with different rhizobia (Phyllobacterium sp. CTEM17, Rhizobium sp. CZ2.7, Ensifer sp. CM61, R. pakistanense CE36 and Neorhizobium sp. CZ4.17) in absence and presence of strain CT7.15 as co-inoculant for 5 months. Values represent mean ± SE, n = 6. Different letters indicate means that are significantly different from each other (GLM, inoculation × co-inoculation; LSD test, p < 0.05). Inoculation, co-inoculation or inoculation × co-inoculation in the corner of the panels indicate main or interaction significant effects (∗ p < 0.001).
